ABSTRACT
This report summarizes the results of a follow-on demonstration test, after a four-phase program
with the U.S. Environmental Protection Agency under Contract 68-D1-0008, "Demonstration of
Fuel Cells to Recover Energy from Landfill Gas." The environmental impact of widespread use of
this concept would be a significant reduction of global warming gas emissions (methane and carbon
dioxide). The follow-on work was conducted over the period from July 1995 through July 1997.
International Fuel Cells Corporation (IFC) conducted the original four-phase program to demon-
strate that fuel cell energy recovery using a commercial phosphoric acid fuel cell is both environ-
mentally sound and commercially feasible. Phase I, a conceptual design and evaluation study, ad-
dressed the technical and economic issues associated with operation of the fuel cell energy recovery
system of landfill gas. Phase II included design, construction and testing of a landfill gas
pretreatment unit (GPU) to remove critical fuel poisons such as sulfur and halides from the landfill
gas, and to design fuel cell modifications to permit operation on low heating value landfill gas. Phase
III was the demonstration test of the complete fuel cell energy recovery system at the Penrose landfill
in Sun Valley, CA. Phase IV described how the commercial fuel cell power plant could be further
modified to achieve full rated power on low heating value landfill gas.
The demonstration test at the Penrose landfill successfully demonstrated operation of the energy re-
covery system, including the GPU and commercial phosphoric acid fuel cell modified for operation
on landfill gas. Demonstration results included operation of the fuel cell up to 137 kW; 37.1 percent
efficiency at 120 kW; exceptionally low secondary emissions (dry gas, 15% QT) of 0.77 ppmV car-
bon monoxide, 0.12 ppmV nitrogen oxides, and undetectable sulfur dioxide; no fuel cell related
forced outages with adjusted availability of 98.5 percent; and a total of 709 hours operation on land-
fill gas. The pretreatment (GPU) operated for a total of 2,297 hours, including the 709 hours with
the fuel cell, and documented total sulfur and halide removal to much lower than specified <3 ppmV
for the fuel cell. The GPU flare safely disposed of the removed landfill gas contaminants by achiev-
ing destruction efficiencies greater man 99 percent.
The follow-on testing was conducted by Northeast Utilities at the Groton, CT landfill. Northeast
Utilities provided the engineering design and construction for the installation and provided the op-
eration and maintenance of the entire follow-on demonstration. IFC and a subsidiary, On-site Power
(ONSI), provided technical support for the follow-on testing.
The follow-on test at the Groton, CT landfill demonstrated the suitability of the landfill gas-to-ener-
gy conversion equipment to operate on a wide range of landfill gas composition. Significant test
results include successful demonstration of transportability of the landfill gas-to-energy equipment,
and operation of the GPU for an additional 4,168 hours (total 6,413 hours) while continuing to re-
move halides and sulfur compounds to much less than the specified <3 ppmV. The fuel cell operated
for an additional 3,313 hours (total 4,020 hours), and demonstrated 38.1% efficiency at 140 kW with
a maximum output of 165 kW. Fuel cell adjusted availability was 96.5%, with one forced outage
in the entire 4,020 hours of operation on landfill gas.

1.0 EXECUTIVE SUMMARY
The U. S. Environmental Protection Agency (EPA) has promulgated standards and guidelines for
the control of air emissions from municipal solid waste (MSW) landfills. This Clean Air Act regula-
tion will result in the control of up to 7 Tg/year of Ctij. The collection and disposal of waste meth-
ane, a significant contributor to the greenhouse effect, would result from the emission regulations.
This EPA action provides an opportunity for energy recovery from the waste methane that could
further benefit the environment. Energy produced from landfill gas could offset the use of foreign
oil, and reduce airemissions affecting global wanning, acid rain, and other health and environmental
issues.
International Fuel Cells Corporation (IFC) was awarded a contract by the US EPA to demonstrate
energy recovery from landfill gas using a commercial phosphoric acid fuel cell. IFC conducted a
four-phase program to show that fuel cell energy recovery is environmentally feasible in commercial
operation. Work was initiated in January 1991. Phase I, a conceptual design and evaluation study,
addressed the problems associated with landfill gas as the feedstock for fuel cell operation.
Phase II of the program included construction and testing of the landfill gas pretreatment module
to be used in the demonstration. Its objective was to determine the effectiveness of the pretreatment
system design in removing critical fuel cell catalyst poisons such as sulfur and halides.
Phase III of this program was a demonstration of the complete fuel cell energy recovery concept.
Phase IV prepared guidelines and recommendations describing how the PC25™ C power plant
could be modified to achieve full-rated power of 200 kW on landfill gas, based upon the experience
gained testing the PC25 A model in this program.
A follow-on phase was added to continue the energy recovery demonstration for an additional year
of operation at a landfill in Groton, CT. The results of the first four phases are summarized in Refer-
ence 1. The results of the follow-on activities are described in this report. This work was conducted
from July 1995 through July 1997, with the 1 year demonstration period from July 15,1996 through
July 15,1997.
The follow-on testing was conducted by Northeast Utilities. Northeast Utilities provided the engi-
neering design and construction for the installation and provided the operation and maintenance for
the entire follow-on demonstration. IFC and ONSI (a subsidiary of IFC) provided technical support
for the follow-on testing.
The objective of the follow-on demonstration is to further demonstrate the suitability of the landfill
gas energy conversion equipment, including a modified commercially available fuel cell power
plant, for future commercial operation on a wide variety of landfills. Specific goals include: 1) dem-
onstrate the transportability of the equipment; 2) demonstrate the adaptability of the demonstration
especially the gas pretreatment unit (GPU), to operation on different landfill gas compositions; 3)
obtain longer term operating data for cost and reliability, including operation of the equipment as
a remote unmanned site; and 4) obtain additional data which could be used to reduce the cost of the
gas cleanup unit.
Figure S-l shows the energy recovery demonstration system installed at the Groton Landfill site.
The demonstration equipment is contained within a 13.1 meter (43 foot) wide by 41 meter (135 foot)
long enclosure surrounded by a chain link fence. The demonstration equipment includes, from left
to right: 1) a small trailer which serves as a temporary office (the site is unmanned) and houses the
GPU controls; 2) the pre-engineered building which houses the Gas Pretreatment Unit (GPU) and
-1-
-------
landfill gas compressor; 4) the commercial fuel cell power plant which has been modified for opera-
tion on landfill gas; and 5) the step-up transformer which boosts the 480 VAC output from the fuel
cell to 13,800 VAC output for use on the utility grid. Not shown on the figure are the GPU flare,
and the existing landfill gas flare and condensate storage tank which are maintained by the Town
of Groton. The site layout showing the location of all the equipment is shown in Figure S-2.
The landfill gas at the Groton landfill was characterized and compared with the Penrose site to deter-
mine if modifications would be required for the demonstration equipment. The results, shown in
Table S-l, show that the Groton landfill gas, with 56.95% methane, is at the high end of landfill gas
compositions, compared with the Penrose site at 44% methane. The higher methane content is re-
sponsible for a 31 % increase in the heating value of the gas at Groton, to 5.22 Kcal/SL. The contami-
nant mix at Groton is also different. Halogenated hydrocarbons as chloride are lower at Groton, 7
to 45 ppmV vs. 45 to 65 ppmV at Penrose. Hydrogen sulfide levels are higher at Groton, at 181
ppmV vs. 100 ppmV at Penrose. Organic sulfur compounds (expressed as equivalent H2S) is lower
at Groton, at 1 ppmV vs. 11 ppmV at Penrose. Due to the higher hydrogen sulfide at Groton, North-
east Utilities installed two additional 992 liter (35 cubic foot) capacity tanks filled with Westates
UOCH-KP carbon, for a longer changeout interval.
A simplified diagram for the demonstration equipment used to process contaminated landfill gas
into clean electric power at the Groton landfill is shown on Figure S-3. The process proceeds from
contaminated landfill gas coming in at the left, with electric power exiting to the right. The shaded
components on the left were added to the demonstration at Groton. The additions include two new
H2S removal beds and the landfill gas compressor rated at 2260 SL/M at 2.76 x 105 Pa (80 scfm at
40 psig). The remaining equipment was transported from the Penrose landfill in Sun Valley, CA.
The impregnated UOCH-KP carbon beds remove virtually all of the hydrogen sulfide. These beds
are not regenerated on site, but the carbon can be removed and regenerated off site if desired. The
gas is regulated down from 2.8 x 105 to 1.5 x 105 Pa, before being cooled to approximately 2° C in
the first stage refrigeration condenser. The condenser stage removes most of the water and some
hydrocarbons, which are removed from the system as a condensate and returned to the Groton site
condensate tank. The next step is a regenerable adsorption bed which removes the water vapor to
a dew point of minus 50° C and also removes additional sulfur and halides. The dry gas is then passed
over a second stage cooler where the gas temperature is reduced to -28° C before going through a
regenerable activated carbon bed at -18° C for final removal of trace hydrocarbons, sulfur, and ha-
lides. The final step is fine pore filtration to remove any particulates or dusting which may come
from the regenerable adsorbent beds. The clean dry gas is regulated down to about 3.5 x 103 Pa pres-
sure. The resulting gas to the fuel cell is approximately 1560 standard liters per minute at 3.5 x 103
Pa pressure with major contaminants reduced to less than 0.025 ppmV total halides and total sulfur.
The dryer and carbon beds are regenerated using clean dry landfill gas from the exit of the
pretreatment system. The regeneration gas is heated to 288° C in an electric heater, and passed
counter-current through the regenerable dryer and activated carbon beds to remove the water and
contaminants. The contaminants are destroyed in a low NOx flare.
The fuel cell section of the demonstration consists of three major subsections: the fuel processor,
the cell stack; and the inverter. The fuel processor removes oxygen and any residual sulfur in the
landfill gas and converts the landfill gas to a hydrogen rich fuel. The next stage in the fuel cell power
plant is the cell stack. The stack converts air and the hydrogen rich fuel from the the fuel processor
to make dc power and thermal energy. DC power is sent to the inverter which converts the dc power
-2-
-------
to 60 cycle ac at 480 volts and provides safe, electrical interconnect to the grid. All heat from the
power plant during the demonstration is rejected to the air by the cooling module.
The fuel cell power plant emits a clean exhaust stream consisting primarily of carbon dioxide, water
vapor, nitrogen, and oxygen. During operation on landfill gas in Phase III the fuel cell exhaust emis-
sions, at 15% oxygen on a dry gas basis, were measured as follows: NOx = 0.12 ppmV; carbon
monoxide = 0.77 ppmV; and SCh = undetectable. These results are discussed in more detail in Sec-
tion 6.3.3 of Reference 1.
The follow-on demonstration results are summarized in Table S-2. The GPU operated for an addi-
tional 4168 hours at Groton for a total of 6465 hours on landfill gas. Gas cleanup performance at
the GPU exit remained significantly better than the design requirements of less than 3 ppmV total
halides (as chloride) and less than 3 ppmV total sulfur (as FbS). Total measured halides varied from
nondetectable to 0.014 ppmV as chloride. Total sulfur varied from nondetectable to a maximum of
0.022 ppmV as FbS. These data indicate the 8,000 hours design life for the GPU beds should be
met and probably exceeded.
Fuel cell powerplant performance at Groton is also improved from 137 kW at Penrose, to 165 kW
at Groton, due to the 31% increase in higher heating value of the Groton landfill gas. Efficiency
also improved, from 37.1% at 120 kW at Penrose, to 38.1% at 140 kW at Groton. The fuel cell oper-
ated for 3313 hours at Groton, for a total of 4022 hours on landfill gas. During this 4022 hours, there
was only one forced outage due to the fuel cell. Fuel cell adjusted availability was 98.5% at Penrose,
and 96.5% at Groton. Based on these results, the fuel cell powerplant operating on landfill gas is
expected to have operation and maintenance cost similar to the PC25 powerplants operating on natu-
ral gas.

2.0 INTRODUCTION
This report summarizes the results of a landfill gas-to-energy demonstration sponsored by the U.
S. Environmental Protection Agency under Contract 68-D1-0008, "Demonstration of Fuel Cells to
Recover Energy from Landfill Gas". The environmental impact of this concept would be a signifi-
cant reduction in global warming gas emissions (methane and carbon monoxide). The work sum-
marized in this report was conducted over the period from July 1995 through July 1997, as a follow-
on to the demonstration conducted at the Penrose Landfill in Sun Valley, CA. from January, 1991
through June, 1995. The California testing is summarized in Reference 1.
The objective of the follow-on demonstration is to further demonstrate the suitability of the landfill
gas energy conversion equipment, including a modified commercially available fuel cell power
plant, for future commercial operation on a wide variety of landfills. Specific goals include: 1) dem-
onstrate the transportability of the equipment; 2) demonstrate the adaptability of the demonstration,
especially the gas cleanup unit (GPU), to operation on different landfill gas compositions; 3) obtain
longer term operating data for cost and reliability, including operation of the equipment as a remote
unmanned site; and 4) obtain additional data which could be used to reduce the cost of the gas clean-
up unit.
The follow-on demonstration was conducted by Northeast Utilities, at the Groton CT landfill.
Northeast designed and constructed the site, and conducted a one year field test from July 15,1996
through July 15,1997. International Fuel Cells and their ONSI subsidiary provided technical sup-
port for the follow-on testing.
Section 3 of this report summarizes the results of the one year demonstration at Groton, CT. The
Groton site design, permitting, and installation activities are described in Section 3.1. This section
compares the Groton landfill gas quality including heating value and contaminant levels to those
found at the Penrose site in Sun Valley CA. This section also describes the modifications made to
the demonstration equipment to permit year round operation at a site where winter temperatures can
fall to below-18°C.
Section 3.2 describes the demonstration test results. Section 3.2.1 summarizes the Test Plan and
Quality Assurance Plan for the 1 year test. Section 3.2.2 summarizes the GPU results, including
operation and reliability, improvements for extended operation, long term contaminant removal per-
formance, and testing conducted to gather data for reducing the cost of the GPU. Section 3.2.3
summarizes the fuel cell performance test results, including operation and reliability, efficiency, and
operating costs.
Section 4 gives the conclusions and recommendations for the one year test at the Groton landfill.

3.0 DEMONSTRATION TEST
3.1 GROTON SITE DESIGN AND INSTALLATION
3.1.1 Site Selection
The site selection criteria for the follow on demonstration were based on EPA's desire to demonstrate
the fuel cell energy conversion system at a wide variety of site conditions using different landfill gas
compositions. The site selection was narrowed down to Connecticut and Massachusetts when
Northeast Utilities became the host utility for the test. The Groton landfill was an ideal site, recently
closed with a cap and collection system installed and a temporary flare in operation. Preliminary
testing indicated adequate gas available at the site, and the Town of Groton was supportive of instal-
ling the demonstration at the site, which presently consists of a transfer station and a recycling facil-
ity for bottles and cans. Special considerations at Groton included lack of sanitary sewers and natural
gas supply at the site.
3.1.2 Comparison Of Groton Landfill Versus Penrose
The first step in the demonstration project is to characterize the landfill gas supply to determine the
suitability for energy recovery. Critical issues include gas availability (flow rate, pressure, and reli-
ability of supply), heating value, and levels of contaminants which could require modification to the
GPU.
Information provided by the Town of Groton indicated the landfill was producing approximately
11,300 SL/M (400 SCFM) of landfill gas, sufficient to support four 200 kW landfill gas fuel cells.
A significant difference between the Groton facility and the Penrose site is pressure of the gas. At
the Penrose site the landfill gas was compressed to 6.9 x 105 Pa (100 PSIG) to support the 8.9 MW
of internal combustion engines at that site. Groton utilizes only a multistage Lamson electric drive
blower to draw the gas out of the landfill at a slight vacuum and push the gas to a temporary flare,
so a compressor would be required for the GPU at the Groton site.
A comparison of the Groton landfill gas composition and heating value vs. the Penrose site is shown
in Table 3.1.2-1. The data include analyses taken in 1995 prior to the demonstration, to June 1997,
near the end of the demonstration test. The fixed gas composition (oxygen, nitrogen, methane, and
carbon dioxide) indicate a high quality gas with higher methane content and less diluents than Pen-
rose. The average methane content at Groton is 56.95% versus 44% at Penrose. The higher methane
content facilitates a higher maximum output from the fuel cell power plant. The average nitrogen
content at Groton is only 1.29% versus 17.6% at Penrose, and the average carbon dioxide content
is 41.34% at Groton versus 38% at Penrose. Oxygen content at Groton averages 0.41% versus 0.4%
at Penrose. In summary, the Groton landfill gas represents a "high end" landfill gas composition
closer to the gas from an anaerobic digester at a waste water treatment plant, while the Penrose site
is a good representative of a lower quality landfill gas from an area where landfill management must
also take into account the competing requirements to minimize methane and NMOC emissions into
the atmosphere.
Table 3.1.2-2 summarizes the results of testing the raw landfill gas at Groton for halogenated hydro-
carbons. The gas samples were taken from September 19,1995 through June 19,1997. A total of
22 compounds was identified. Total halogenated species varied from 5.463 ppmV to 7.345 ppmV
on September 19,1995, to a maximum of 13.136 ppmV on November 1,1995, declining to 3.085
ppmV on the last sample taken on June 19,1997. The most significant change is in the dichlorodi-
fluoromethane, which peaked at 10.2 ppmV on November 11,1995 and declined to 0.84 ppmV on
-8-
-------
June 19,1997. The total halogen as chlorides (equal to the sum of the individual species times the
number of halogen atoms per each species) varied from about 16 ppmV to 45 ppmV. This is less
than the 45 ppmV to 65 ppmV found at the Penrose site, and indicated that no modifications were
required to the low temperature carbon beds in the GPU for the Groton site. Total halogens declined
to 7 ppmV on June 19,1997 near the end of the test.
The concentration of hydrogen sulfide (H^S) varied considerably before and during the demonstra-
tion test period. Data from 28 individual wells taken on December 29,1994 (Table 3.1.2-3) shows
concentrations varying from 17 to 2000 ppmV, with an arithmetic average concentration of 430
ppmV. A sample taken at the town flare on January 11,1995 tested at 1380 ppmV H2S. The HaS
levels at Groton were significantly higher than the 100 ppmV HaS measured at Penrose and would
require higher capacity sulfur removal beds to reduce the operating and maintenance cost associated
with the bed changeouts.
Northeast Utilities procured on site measuring equipment (Draeger pump and glass measuring
tubes) to measure H2S in the raw landfill gas. The results, summarized in Figure 3.1.2-1 confirmed
that the H2S is much higher than measured at Penrose, but has declined significantly with time.
Northeast measured H2S levels from 500 ppmV to 300 ppmV during March 1996, and selected 500
ppmV as the basis for sizing the hydrogen sulfide removal beds for the GPU. The F^S levels as
measured by the Draeger tube have continued to decline, reaching a low of just 18 ppmV on May
5, 1997. The average raw landfill gas concentration for the period from March 12, 1997 through
May 5,1997 is 181 ppmV.
An analysis for organic sulfur compounds prior to the demonstration on January 11,1996, showed
0.9 ppmV dimethyl sulfide. The remaining organic sulfur compounds (dimethyl disulfide, methyl
mercaptan, carbonyl sulfide, and carbon disulfide) were not detected at a 0.1 ppmV detection limit.
These low levels of organic sulfur would not require any modification to the GPU.

3.1.3 Permitting
Northeast Utilities is exempt from local permitting requirements due to its status as a regulated util-
ity. However, all new facilities must be reviewed and approved by the Connecticut Siting Council.
Application was made to the Connecticut Siting Council on October 1995. After the required public
hearings, a permit was granted on January 23,1996.
The State of Connecticut has approved a blanket exemption for fuel cells for air emissions permit-
ting, so no air permitting was required for the demonstration project at Groton. The State also regu-
lates water discharges, and required Northeast to provide water analyses from the fuel cell, which
can produce a small overflow of clean condensate water from the water treatment system. This con-
densate flow is normally directed into a sanitary sewer, which was not available at the Groton site.
3.1.4 Modifications for Groton Site
A photograph of the completed site is shown in Figure 3.1.4-1. The entire site is enclosed within
a 13 meter wide by 41 meter long (43 foot x 135 foot) security fence and the surface is covered with
crushed rock for dust and weed suppression. The existing LFG blower, flare, and a condensate tank
owned by the town of Groton are included at the south end of the site.

-------
The Groton fuel cell site layout and a listing of the major modifications is shown in Figure 3.1.4-2.
The most significant modification for the Groton site is the addition of a pre-engineered all-weather
building to house the GPU and all associated gas processing equipment. The building is 6.1 meters
x 9.1 meters (20 feet by 30 feet), and includes heating, ventilation, and a combustible gas sensor.
The building was added to protect against potential freezing of wet landfill gas and the associated
condensate, since the GPU was originally designed and specified for the non-freezing climate at the
Penrose site in southern California.
The second major modification for the Groton site was the addition of a landfill gas compressor to
replace the 6.90 x 105 Pa (100 PSIG) landfill gas supply which was available at the Penrose site.
Northeast Utilities installed a Norwalk dual piston positive displacement, lubrication free continu-
ous duty compressor Model NQ-DV1-O (SVDA) rated for 2260 SL/M at 2.76 x 105 Pa (80 SCFM
at 40 PSIG). This gas supply was regulated down to approximately 1.52 x 105 Pa (22 PSIG) at the
inlet to the GPU.

-------
Based on the estimated 500 ppmV hydrogen sulfide in the landfill gas (see Section 3.1.2), the FbS
removal beds were modified to increase capacity compared to the Penrose site, where the FbS con-
centration averaged only 100 ppmV. Two 992 liter (35 cubic foot) capacity tanks were installed and
filled with Westates UOCH-KP carbon. A photograph of the carbon bed installation is shown in
Figure 3.1.4-3. The beds are plumbed so either bed can be isolated from the gas flow, to facilitate
bed changeout "on the fly". A compressor bypass line returns excess flow back to the inlet of H2S
removal tank #1 during periods when the GPU is operating without the fuel cell, or when the fuel
cell is operating at low power. For normal operation the two beds are operated in series to provide
maximum protection against breakthrough. The projected life for the two beds operating in series
was conservatively estimated at over 3 months, based on continuous 140 kW operation with 500
ppmV FhS in the landfill gas.
CA-0223
Figure 3.1.4-3. High Capacity Hydrogen Sulfide Removal Tank
Installation at Groton Landfill
An air compressor was also added to provide muscle air for the pneumatic valves used on the GPU,
since no compressed air is available at the Groton site. Northeast Utilities initially installed a small
compressor, with bottle nitrogen for a backup. This was replaced with an industrial grade compres-
sor, and the bottled nitrogen was eliminated from the system.
The final modification was the addition of compressed natural gas to the site, to provide start up fuel
for the GPU flare, and for the reformer start burner in the fuel cell. This change was required because
the site does not have a pipeline natural gas supply.
The P&ID (Process and Instrumentations Diagram) for the Groton fuel cell facility is shown in Fig-
ure 3.1.4-4. The existing equipment and the new equipment for the fuel cell demonstration are in-
cluded. The 3 sampling locations for obtaining landfill gas are shown.

3.2 DEMONSTRATION TEST RESULTS
3.2.1 Test Plan and Quality Assurance
The objective of the follow-on demonstration is to further demonstrate the suitability of the landfill
gas energy conversion equipment, including a modified commercially available fuel cell power
plant, for future commercial operation on a wide variety of landfills. Specific goals include: 1) dem-
onstrate the transportability of the equipment; 2) demonstrate the adaptability of the demonstration,
especially the gas cleanup unit (GPU), to operation on different landfill gas compositions; 3) obtain
longer term operating data for cost and reliability, including operation of the equipment as a remote
unmanned site; and 4) obtain additional data which could be used to reduce the cost of the gas clean-
up unit.
The test plan was to continue the demonstration test begun at the Penrose site for an additional year.
Operating output was to be increased to 140 kW if possible. Gas analyses would be conducted in
the same way as at Penrose to maintain a consistent data set.
The data measurement summary for the Groton demonstration is given in Table 3.2.1-1. Landfill
gas analyses include sulfur compounds measured by EPA method 16 and 18, volatile organic com-
pounds (including halides) measured by EPA method TO-14, and GPU output gas heat content mea-
sured by ASTM D3588-91. The majority of these critical gas analyses were provided by Perfor-
mance Analytical, Inc. in Canoga Park, CA. Performance Analytical was selected because they were
the contractor for the Penrose testing, and performed admirably during the testing and for the quality
assurance tests required by EPA. In addition to the sulfur and VOC analyses, Performance Analyti-
cal also analyzed for heat content, so all critical analyses were obtained from a common sample.
GPU exit samples were taken in an evacuated stainless steel summa canister. Additional gas sam-
ples, especially raw landfill gas containing H2S (which can be adsorbed onto the summa canister
walls) were taken in Tedlar bags. The sampling technique was observed by the EPA Quality Assur-
ance Officer during an on-site visit to the Groton site on May 19,1997. Performance Analytical in-
cluded method blanks and duplicate test analyses with all reports.

The Performance Analytical H^S measurements were supplemented by more frequent readings tak-
en by Northeast Utilities using Draeger Tubes. These readings were taken to provide a more detailed
history of the raw landfill gas sulfur content, which appeared to be changing with time, and to moni-
tor the performance of the H2S removal bed, for changeout.
The remaining data are site readings taken by Northeast Utilities personnel from the nearby Mont-
ville generating station. Data from these site readings include GPU output gas cumulative flow rate
and fuel cell electrical output (for determining fuel cell efficiency). Copies of these site logs are
attached in Appendix A.
A summary of all gas analyses used in this report is shown in Table 3.2.1-2. This table includes data
which were obtained from local suppliers prior to the demonstration test. Table 3.2.1-1 includes the
sample date and time, location, GPU hours and process counter, type of sample container, name of
analysis lab, analyses performed including duplicates and blanks, and fuel cell power level. The gas
sampling locations are shown in Figure 3.1.4-4. A complete collection of all gas analyses is provided
in Appendix B.

3.2.2 GPU Performance
3.2.2.1 Operation and Reliability
The GPU operated for 4168 hours during the demonstration period in 32 runs, with the longest run
being 827 hours. During this time, Northeast Utilities identified and corrected all recurring causes
of GPU shutdowns, so that by the end of the demonstration period the sole remaining cause of shut-
downs was the landfill gas compressor, which was the major new piece of equipment (with the least
development time on landfill gas) which was added to the demonstration at Groton. The compressor
shutdowns were caused by excessive wear on the exhaust valves, which required replacement every
6 to 8 weeks. (The manufacturer has identified a fix to the problem, but it was not available until
after the end of the demonstration test period).
The Groton GPU run summary, including start and stop dates and times, period run hours/ Groton
run hours/ total run hours, reason for shutdown, and corrective actions taken, is shown in Table
3.2.2.1-1. There were 32 GPU runs beginning with run G-0 on June 17,1996 and ending with run
G-31 which shut down on July 14,1997 after a continuous run of 827 hours. The 32 shutdowns can
be summarized as follows: 21 forced outages due to the GPU; 5 voluntary shutdowns; 4 grid outage
related shutdowns; and 2 fuel cell related shutdowns. An uninterruptible power supply was installed
on the instrument and control circuit for the GPU and compressor in early 1997, to prevent additional
shutdowns due to momentary grid outages. Of the 21 GPU related shutdowns, about half were one-
of -a-kind mechanical failures which were corrected and did not reoccur. The remainder were due
to 3 system issues which were diagnosed during the demonstration test: (1) recurring high GPU pres-
sure drop was corrected by adding two new coalescing filters and water traps in September 1996 to
prevent any landfill gas condensate from entering the small rbS removal bed downstream of the
compressor, which caused carbon to escape from the bed and cause blockage of downstream regula-
tors and the coalescing filter; (2) periodic freeze-ups of the refrigeration system were eliminated by
adding an in-line dryer to the d-Iimonene refrigerant in May of 1997 (this is in addition to the d-limo-
nene air vent dryer which was installed based on the Penrose operating experience); and (3), an im-
proved landfill gas compressor exhaust valve was identified to prevent periodic failures which oc-
curred about every 6 to 8 weeks. This last fix was not available for installation until after the
completion of the demonstration test on July 15,1997. As a result of these improvements, run times
steadily increased, to an average of 370 hours (over 15 days) for the last 7 runs, and the last two runs
were 359 and 827 hours. The last two shutdowns were caused by the compressor valves.
The gross availability of the GPU for the demonstration test period from July 15,1996 to July 15,
1997 is 45%. Most of the GPU down time occurred during the first 6 months of the period, when
the one-time mechanical failures were resolved, and the recurring issues which required system fixes
became evident. Several of these failures required considerable non-recurring troubleshooting time
to determine the root cause, and to design a suitable solution to the problem, then procure and install
the appropriate fix. Manpower availability was also occasionally an issue, since the manpower as-
signed to the demonstration project were based at a 440 MW generating plant whose operation took
priority over the demonstration. The GPU availability for the second half of the demonstration peri-
od improved to 70% from February 11, 1996 through July 14,1997.

3.2.2.2 Contaminant Removal Performance
The GPU has continued to remove sulfur and halide compounds to well below the design limits of
3 ppmV total sulfur and less than 3 ppmV total halides during the extended demonstration test at
Groton. Data from the standard surnma canisters at normal GPU operating conditions showed no
detectable sulfur or halides through June 16,1997 (5805 total GPU hours), and only trace increases
out to July 9,1997 (6286 total GPU operating hours, or 8.7 months). The July 9,1997 data was
taken during a test of simplified GPU operating conditions which are believed to be the cause of the
slight increase in exit halogens (see discussion in Section 3.2.2.4). The continuing low exit levels
of sulfur and halide compounds indicate that the original GPU bed design life of 8,000 hours is likely
to be achieved.
The contaminant removal performance data at the GPU exit from the Groton Connecticut landfill
is summarized in Table 3.2.2.2-1. A single exit sample was taken at Groton before the beginning
of the one year test, on June 19,1996 to verify that the GPU was still removing total sulfur and total
halides to less than 3 ppmV. Total sulfur measured 0.022 ppmV (all as carbonyl sulfide), and total
halides measured 0.014 ppm V (all as methylene chloride) met the requirements and the one year test
was initiated.
During the demonstration test, exit gas samples were then taken from both parallel sets of beds in
the GPU (dryer bed DAB105 plus carbon bed CAB107, and dryer bed DAB104 plus carbon bed
CAB106) on March 20,1997, May 19,1997, June 19,1997, and July 9,1997. Total sulfur remained
below detection limits through June 19,1997, when measured from the summa canister, but dupli-
cate analyses from Tedlar bags on June 19, 1997 indicated 0.017 ppmV carbon disulfide (0.033
ppm V total sulfur as foS) at 5803 hours, and 0.014 ppm V carbon disulfide (0.027) ppmV total sulfur
as H2S) at 5805 hours. This finding raises the possibility that low levels of carbon disulfide may
adsorb onto the summa canister walls. These low levels of organic sulfur are not a concern to the
fuel cell, which contains a fuel preprocessor designed to remove up to 30 ppmV of organic sulfur
from natural gas.
The GPU exit total halide results also show no detectable halides through June 19,1997. A slight
increase to 0.012 ppmV and 0.019 ppmV on July 9,1997 is due to a change in GPU operating condi-
tions as part of a test to obtain data for reducing the cost of the GPU (see Section 3.2.2.4).

3.2.2.3 GPU Exit Gas Heat Content
The summary of ASTM method heat content measurements at the Groton landfill is compared to
the average values taken at Penrose in Table 3.2.2.3-1. The heating values are reported on a dry gas
basis at 15.6°C and 1.01 x 105 Pa (60 degrees F, 14.696 psia), from gas samples taken at the GPU
exit. The average higher heating value at Groton is 5.18 Kcal/SL (580.6 Btu/cubic foot) versus 3.98
Kcal/SL (445.8 Btu/cubic foot) at Penrose. The most significant difference is the lower nitrogen
content and higher methane content in the Groton gas. Both sites contained very little higher hydro-
carbons, with Groton measuring none heavier than methane, and Penrose measuring just 0.02%
ethane. A sample of raw landfill gas at Groton measured 0.01% heavier than hetfanes, indicating
the low concentration of heavier compounds in the GPU exit gas is due to the incoming gas, rather
than removal of heavier compounds by the GPU.

3.2.2.4 Testing for Reduced Cost GPU
An objective of the Groton testing is to demonstrate means to reduce the cost of the GPU. The proj-
ected cost of the commercial scale, 800 kW, GPU included in the original economic study reported
in Section 3 of Reference 1 is $190 per kW. This cost projection was based on scale-up and simplifi-
cation of the 200 kW demonstrator equipment, plus higher production volume. Testing was under-
taken at Groton to demonstrate a significant simplification to the present demonstrator GPU.
-26-
-------
The proposed simplification approach is to combine the dryer bed and carbon bed media into a single
vessel. This approach eliminates 2 vessels and the low temperature cooler, along with the associated
valves, plumbing, instrumentation, and simplifies the refrigeration system.
On July 9, 1997 GPU exit gas samples were taken as part of a test to determine the feasibility of
reducing the cost of the GPU by combining the two dryer beds plus the two final carbon beds into
just two vessels instead of the 4 vessels currently used. The objective of the test was to determine
if the carbon beds would maintain acceptable performance if the temperature were increased from
the normal -18°C (0 degrees F) to about 2°C (35 degrees F) which is the inlet temperature to the
dryer beds. The temperature setpoint of the GPU refrigeration system was increased to raise the
temperature of the d-limonene refrigerant used to cool the carbon beds. The inlet gas temperature
to the carbon bed was limited to about -11 °C (12 degrees F) by the refrigeration unit controller but
the GPU strip chart showed that it takes several hours for the carbon bed to achieve this low tempera-
ture, so that a sample taken early in the make cycle would have a higher average temperature. GPU
exit gas samples were taken near the end of the make cycle, at 48,600 counts, and near the beginning
of the make cycle, at 600 counts when the average bed temperature was 20°C (68 degrees F). The
results are shown in the last two columns of Table 3.2.2.2-1 and in Table 3.2.2.4-1. The data taken
near the end of the make cycle at 48,600 counts show a slight increase in carbonyl sulfide and total
halides. Carbonyl sulfide was detected at 0.010 ppmV, which is less than the maximum detected
previously at Groton and at Penrose. The regular halogens were non-detected, but low levels of chlo-
romethane (0.012 ppmV) and bromomethane (0.00044 ppmV) were detected. The data taken early
in the make cycle at 600 counts with an average carbon bed temperature of 20°C show additional
increases in carbonyl sulfide, which increases to 0.080 ppmV, and total halides which increase to
0.019 ppmV (consisting of 0.00026 ppmV methylene chloride, 0.002 ppmV vinyl chloride, 0.013
ppmV chloromethane, 0.00044 ppmV bromomethane, and 0.00033 trichlorofluoromethane). The
data summary in Table 3.2.2.4-1 indicates that operation of the carbon bed in the dryer bed vessel
at 2°C may be feasible. The effect of the low halide levels on long term fuel processor life would
need to be reviewed.

The initial GPU, while technically successful, requires high production volume and large scale (800
kW) units to meet overall cost objectives. As a result of this demonstration IFC recommends a lower
cost approach which has the potential to meet the $190/kW cost goal at lower production volume
and smaller scale. This approach dramatically simplifies the GPU by upgrading the existing fuel
cell power plant gas cleanup system to remove halides, so most of the GPU active components can
be eliminated.
The second approach to GPU cost reduction is based on experience with gas cleanup for waste water
treatment plants, where the HhS is removed in the same type of impregnated carbon bed used in the
landfill GPU, and the halides are removed inside the PC25 C power plant. This approach utilizes
the existing hydrotreater bed in the power plant to react the halogenated hydrocarbons to HC1, HF,
-27-
-------
and HBr, which in turn are removed over a bed of commercially available halogen guard material.
Testing demonstrating bydrotreating and disposable absorbents as a means to remove halides from
landfill gas have been reported in the literature (Reference 2). Tests to confirm the feasibility of this
approach are also planned under an EPA sponsored program using a 200 kW fuel cell at an existing
waste water treatment plant in Yonkers, New York.
Landfill gas analyses were taken at the inlet and exit of the P^S beds, to determine the effect of the
impregnated carbon on the levels of organic sulfur compounds, and volatile organic compounds in-
cluding halogenated species. The effect of the H2$ removal beds on hbS and organic sulfur com-
pounds is shown in Table 3.2.2.4-2. In addition to the 117 ppmV of hydrogen sulfide removed, the
impregnated carbon also caused a net reduction in total organic sulfur species of 0.388 ppmV (equiv-
alent to 0.457 ppmV as HoS). Species reduced include methyl mercaptan (-0.095 ppmV), ethyl mer-
captan (- 0.127 ppmV), carbon disulfide (- 0.068 ppmV), isopropyl mercaptan (- 0.068 ppmV), and
thiophene (- 0.074 ppmV). Increases in dimethyl sulfide (0.072 ppmV) and dimethyl disulfide
(0.002 ppmV) were recorded.
The effect of the H2S removal beds on volatile organic compounds is shown in Table 3.2.2A-3.
Most halogenated compounds showed slight increases in concentration at the exit, with an overall
increase in total halogen content of 1.489 ppmV as chloride. A possible explanation for this result
is that the impregnated carbon initially absorbs halogenated species, which are then gradually driven
off as the bed removes hydrogen sulfide and converts it to elemental sulfur.
The small changes observed in total sulfur as H2S and total halides as chloride exiting the H2S carbon
bed are not expected to have any significant impact on the feasibility of using the fuel cell hydrotreat-
er bed and a halide guard bed.

3.2.3 Fuel Cell Performance
3.2.3.1 Operation and Reliability
The fuel cell operation on landfill gas at Groton is summarized in Table 3.2.3.1-1. The fuel cell ran
for a total of 3313 hours on landfill gas in 16 runs at the Groton landfill. Total operating time on
landfill gas is 4020 hours (5.5 months), including the 707 hours at Penrose. Total fuel cell operating
time is 4,135 hours, which includes 115 hours operation on natural gas at Penrose during initial
checkouts. The longest Groton run was Run 16, at 825 hours. There was one forced outage caused
by the fuel cell. The adjusted reliability for the fuel cell was 96.5%.
The causes for the 16 shutdowns can be categorized as follows: 11 due to GPU shutdowns (see sec-
tion 3.2.2.1); 4 site related (3 due to loss of grid power and 1 due to loss of site landfill gas supply);
and 1 due to mechanical failure within the fuel cell power plant. The fuel cell shut down on February
4,1997 was due to failure of several electrical space heating elements inside the fuel cell, which in
turn resulted in damage to a pump, valve and flow switch due to freezing. The mechanical compo-
nents and heaters were replaced, and normal operation was resumed.
The raw availability of the fuel cell is: 3313/8760 = 38%. As discussed in section 3.2.2.1, the avail-
ability of the demonstration improved during the second half of the demonstration test at Groton.
The raw availability for the last 5 runs from February 11,1997 through July 14,1997 improved to
67%.
The fuel cell adjusted availability was computed as follows:
• Fuel cell availability is adjusted to compensate for factors which are not caused by the pow-
er plant, as follows:
Raw availability (OPERATING TIME divided by elapsed clock time since first start) is
adjusted to account for
unforced outages not due to power plant
shutdowns due to operator error
waiting time for replacement parts where parts were recommended the customer
have on hand
periods of time when power plant could be worked but manpower not available
(weekends, vacations)
... f . .. .... OPERATING HOURS
Adjusted availability = — ——;—: :
[(elapsed clock time) - adjustment]
The adjusted availability for the fuel cell for the 1 year test is:
33137(8760-5328) = 96.5%

3.2.3.2 Efficiency
Fuel cell efficiency was calculated over a 9 day period from June 10,1997 through June 19,1997,
while the fuel cell was operating at a constant 140 kW. Efficiency during this 9 day period of contin-
uous operation was 38.1% on a lower heating value basis. This calculated efficiency is slightly high-
er than the 37.1% efficiency calculated over a continuous 6 day period at 120 kW at the Penrose
landfill in California, where the heating value of the landfill gas is lower.
The details of the efficiency calculation are summarized in Table 3.2.3.2-1. The fuel cell net energy
output was measured using the fuel cell output voltage and amperage sensors, with an adjustment
factor based on a comparison of the fuel cell calculations with the utility calibrated site meter used
at Penrose. The gas consumption by the fuel cell was measured at the GPU exit using the same Yoko-
gawa YFCT Flow Computing Totalizer (Style B) used at Penrose, with an adjustment to correct for
a compensating temperature which was reading erroneously low during this time. The heating value
used were the average of the samples taken on June 19,1997, near the end of the 9 day period.

3.2.3.3 Maintenance and Operator Requirements
The operation and maintenance cost factors for the landfill gas fuel cell power plant are compared
with the PC25A commerctatfuel cell experience in Table 3.2.3.3-1. After 3313 hours operation on
landfill gas at Groton, and ?020 total hours including Penrose, the O&M cost factors for the landfill
gas fuel cell power plant continue to be comparable to the natural gas power plant.

Operation factors for the landfill gas fuel cell power plant demonstration including start-up, normal
operation, and availability continue to be comparable to natural gas. Availability, at 96.5% for Gro-
ton, continues to be slightly better than the 95% for the natural gas, and would be expected to be
similar to the commercial natural gas power plants in the future. The electrical efficiency on landfill
gas is 38% at Groton, slightly lower than the 40% for natural gas, but this is partially offset by the
lower cost for the landfill gas fuel. Rated output for the Groton site is 140 kW (maximum 165 kW),
which is improved from the 120 kW (maximum 137 kW) rating at Penrose, due to the higher heating
value for the landfill gas at Groton. The means to achieve 200 kW using a PC25 C power plant are
discussed in REF 1.
-34-
-------
The maintenance cost factors for unscheduled maintenance continue to project to be comparable to
the natural gas power plant based on the comparable forced outage rating (1 forced outage in 4020
total landfill gas operating hours, versus 2600 hours MTBFO for commercial PC25 A natural gas
power plants).

4.0 CONCLUSIONS AND RECOMMENDATIONS
1. The landfill gas-to-energy demonstration equipment, including the fuel cell and Gas Pretreat-
ment Unit (GPU) were removed from the Perirose, CA. site, transported to the Groton, CT. site,
re-installed, and successfully operated for a year. This test demonstrated the transportability, of
the equipment and the applicability of the equipment to varying landfill gas compositions, and
climatic conditions.
2. The GPU for cleaning the landfill gas was successfully adapted to a new landfill site and demon-
strated the following:
• Operated for an additional 4,168 hours at Groton (total of 6,413 hours)
• Longest run of 827 hours
• Documented total sulfur removal significantly better than the design requirement (less
than 3 ppmV)
• Documented total halide removal significantly better than the design requirement re-
quired (less than 3 ppmV total halides)
• Demonstrated use of reduced cost commercial sulfur removal tanks with extended
changeout interval
3. The commercial PC25 A fuel cell, modified for operation on landfill gas, was restarted and suc-
cessfully demonstrated the following:
• Operation up to 165 kW on landfill gas
• Efficiency of 38.1% at 140 kW
• Additional 3,313 hours operation on landfill gas (total 4,020 hours)
• Adjusted availability of 96.5%, with only one forced outage in the 3,313 hours
4. Tests were completed to determine means to reduce the cost of the GPU. Based on these tests,
the recommended approach for a low cost GPU consists of external F^S removal, followed by
organic sulfur and organic halide removal within the fuel cell power plant.

Subject: Groton Landfill Gas Analysis - January 11, 1996
As requested, we analyzed two gas samples from the Town of Groton landfill
delivered to the lab on January 11, 1996 for halogenated compounds, oxygen,
nitrogen, methane, carbon monoxide, carbon dioxide and heat content. We tested
for halogenated compounds found on the EPA SW846 Method 8010 list using a
modified purge & trap procedure. Since bag ftl was leaking it was jiot ^tested_
for halogenated compounds. Heat content was calculated basecTon"test"results
below. Our results follow:

Volatile Organic Compound Analysis
The sample was also analyzed by combined gas chromatography/mass spectrometry (GC/MS) for volatile
organic compounds. The analyses were performed according to the methodology outlined in EPA
Method TO-14 from the Compendium of Methods for the Determination of Toxic Organic Compounds
in Ambient Air, EPA 600/4-84-041, U.S. Environmental Protection Agency, Research Triangle Park,
NC, April, 1984 and May, 1988. The analyses were performed by gas chromatography/mass
spectrometry, utilizing a direct cryogenic trapping technique. The analytical system used was comprised
of a Hewlett Packard Model 5989 GC/MS/DS interfaced to an Entech 7000 automated whole air inlet
system/cryogenic concentrator. A 100% Dimethylpolysiloxane capillary column (RTX-1, Restek
Corporation, Bellefonte, PA) was used to achieve chromatographic separation.
The results of analyses are given on the attached data summary sheets.

Fixed Gases Analysis
The sample three samples were also analyzed for fixed gases (Hydrogen, Oxygen, Nitrogen, Carbon
monoxide, Methane and Carbon dioxide) using a Hewlett Packard Model 5890 gas chromatograph
equipped with a thermal conductivity detector (TCD).
Sulfur Analysis
All of the samples were analyzed for twenty Sulfur compounds by gas chromatography/flame photometric
detection (FPD). The analytical system used was comprised of a Hewlett Packard Model 5890 equipped
with a flame photometric detector (FPD).
Volatile OtganicCompounds Analysis
Four of the samples were analyzed by combined gas chromatography/mass spectrometry (GC/MS) for
volatile organic compounds. The analyses were performed according to the methodology outlined in
EPA Method TO-14 from the Compendium of Methods for the Determination of Toxic Organic
Compounds in Ambient Air. EPA 600/4-84-041, U.S. Environmental Protection Agency, Research
Triangle Park, NC, April, 1984 and May, 1988. The method was modified for using Tedlar bags. The
analyses were performed by gas chromatography/mass spectrometry, utilizing a direct cryogenic trapping
technique. The analytical systems used were comprised of a Finnigan Model 4500 GC/MS/DS interfaced
to a Tekmar 5010 Automatic Desorber and a Hewlett Packard Model 5972 GC/MS/DS interfaced to an
Entech 7000 automated whole air inlet system/cryogenic concentrator. A 100% Dimethylpolysiloxane
capillary column (RTX-1, Restek Corporation, Bellefonte, PA) was used to achieve chromatographic
separation.
The results of analyses are given on the attached data sheets.

Fixed Gases Analysis
The seme sample was also analyzed for fixed gases (Hydrogen, Oxygen, Nitrogen, Carbon monoxide,
Methane and Carbon dioxide) using a Hewlett Packard Model 5890 gas chromatograph equipped with a
thermal conductivity detector (TCD).
Sulfur Analysis
Both of the samples were analyzed for twenty Sulfur compounds by gas chromatography/flame
photometric detection (FPD). The analytical system used was comprised of a Hewlett Packard Model
5890 equipped with a flame photometric detector (FPD).
Volatile Organic Compounds Analysis
Both samples were also analyzed by combined gas chromatography/mass spectrometry (GC/MS) for
volatile organic compounds. The analyses were performed according to the methodology outlined in
EPA Method TO-14 from the Compendium of Methods for the .Determination of Toxic Organic
Compounds in Ambient Air. EPA 600/4-84-041, U.S. Environmental Protection Agency, Research
Triangle Park, NC, April, 1984 and May, 1988. The method was modified for using Tedlar bags. The
analyses were performed by gas chromatography/mass spectrometry, utilizing a direct cryogenic trapping
technique. The analytical system used was comprised of a Hewlett Packard Model 5973 GC/MS/DS
interfaced to a Tekmar AUTOCan Elite automated whole air inlet system/cryogenic concentrator. A
100% Dimethylpolysiloxane capillary column (RTi-1, Restek Corporation, Bellefonte, PA) was used to
achieve chromatographic separation.
The results of analyses are given on the attached data sheets.

16. ABSTRACT
The report summarizes the results c: follow-on tests, following a four-
phase EPA program. The environmental impact of widespread use of this concept
would be a significant reduction of global warming gas emissions (methane and car-
bon dioxide). The follow-on testing, conducted by Northeast Utilities at the Groton,
CT, landfill, indicated the suitability of the landfill-gas-to-energy conversion
equipment to operate on a wide range of landfill gas compositions. Significant test
results include successful transportability of the landfill-gas-to-energy equipment,
and operation of the gas pretreatment unit (GPU) for an additional 4168 hours (total
of 6413 hours) while continuing to remove halides and sulfur compounds to much
less than the specified <3 ppmV. The fuel cell operated for an additional 3313 hours
(total of 4020 hours), and reflected 38.1% efficiency at 140 kW with a maximum out-
put of 155 kW. Fuel cell adjusted availability was 96. 5%, with one forced outage in
the entire 4020 hours of operation on landfill gas. International Fuel Cells Corpora-
tion conducted the original four-phase program to show that fuel cell energy reco-
very using a commercial phosphoric acid fuel cell is both environmentally sound
and commercially feasible. The original program was conducted at the Penrose land
fill in Sun Valley, CA.
