DANBURY, CT - The U.S. Department of Energy has approved
plans to shift the site of the world's first fuel cell to be linked to
a clean coal technology power plant – a move that will give the
power industry an earlier-than-expected preview of a super-clean, high-efficiency,
coal-fueled generating system.
The department said today that it has given the go-ahead to FuelCell
Energy Inc., Danbury, Conn., to install a two-megawatt fuel cell power
plant at the Wabash River Energy, Ltd., coal gasification-combined cycle
power plant in West Terre Haute, Ind. Original plans called for the fuel
cell to be installed at the Kentucky Pioneer Energy, Ltd., gasification
power plant near Trapp, Kentucky.
Both sites are owned by Global Energy, Inc., Cincinnati, Ohio, and both
projects are part of the Energy Department's Clean Coal Technology Demonstration
Program. The Kentucky project, however, is still in the design and permitting
phase, while the Wabash River Energy plant has been operating since 1995.
"Relocating the fuel cell to an operating clean coal plant will
give us a two-year jump start on demonstrating a high-tech power system
that virtually eliminates air pollutants and significantly reduces greenhouse
gas emissions," Secretary of Energy Spencer Abraham said. "President
Bush has highlighted both clean coal technologies and fuel cells in his
Clear Skies and Climate Change Initiatives, and this gives us a way to
bring both together in an early preview of a possible power plant of the
future."
FuelCell Energy's Direct FuelCell® generates electricity with no
combustion. Instead it uses an electrochemical reaction between fuel and
oxygen from the air to produce electric power. Since no fuel is burned,
there are none of the pollutants commonly associated with the combustion
of fossil fuels. In fact, many States have classified fuel cells as the
environmental equivalent of wind and solar energy.
Most fuel cells entering commercial markets today are designed to use
natural gas or methane gas produced from municipal waste treatment plants.
The fuel cell planned for the Wabash River plant will be the largest ever
to be fueled by gas made from coal.
FuelCell Energy has been working with the Energy Department's National
Energy Technology Laboratory since the 1970s to develop fuel cell systems
for electric power generation.
The National Energy Technology Laboratory also oversees the Clean Coal
Technology Program and, in 1991 added the Wabash River Project to the
joint government-industry clean coal program.
Instead of burning coal like a conventional power plant, the Wabash River
plant breaks coal apart into a gaseous mixture. More than 97 percent of
the pollutant-forming sulfur impurities are cleaned from the gas before
it is sent to a gas turbine to generate electric power. To boost power
generating efficiencies, the turbine's hot exhaust is captured and used
to make steam for a conventional steam turbine. With this type of gasification
system, there are virtually no sulfur, nitrogen, or ash particle emissions.
The 260-megawatt Wabash River plant has been operating since November
1995 and is currently one of only two commercial-scale coal gasification
power plants running in the United States. In 1999, the Energy Department
added the Kentucky Pioneer Energy project to the Clean Coal Technology
Program to demonstrate another configuration for gasification power plants.
Currently construction of the Kentucky project is slated to begin in early
2004 with operations beginning in mid-2005 at the earliest.
FuelCell Energy expects to be ready to ship the fuel cell from its Torrington,
Conn., fabrication plant to the Wabash River site in the second half of
2003. By the time it arrives at the site, the fuel cell will have been
assembled and tested on natural gas at the Torrington facility. A one-year
test program would begin soon after the fuel cell arrives and is connected
to the coal gas system. After the test period, Global plans to leave the
fuel cell in place and use its electrical output to operate the Wabash
River plant. The will allow the plant to send more power to the grid.
Engineers plan to begin preparing the Wabash River plant to receive the
fuel cell as soon as environmental approvals are received. Plant modifications
primarily involve installing ducts and other equipment to divert a portion
of the clean coal gas from the main power system to the fuel cell.
The project cost will be $32.3 million, half of which will be provided
by the Energy Department. |
