Fuel Cell Project Linking With FutureGen?

FuelCell Energy Inc., citing a possible link-up with the Energy
Department's FutureGen coal gasification and power plant project,
announced this week it has finalized terms on a $6.2 million DOE grant
backing the development a "multi-megawatt" solid oxide fuel cell power
plant that could run on coal synthesis gas. The grant provides funding
for the first stage of the 10-year, three- phase Fuel Cell Coal-Based
Systems project, which is part of the DOE Office of Fossil Energy's
Solid State Energy Conversion Alliance (SECA). Total project funding
for this and the other two planned phases is expected to be about $80
million.

The project is aimed at developing solid oxide fuel cell (SOFC)
technology that can run on coal gas and be used in highly-efficient
central generation power plant facilities.

The goal is to demonstrate an advanced fuel cell-hybrid system with an
overall efficiency of at least 50 percent in converting energy
contained in coal to grid electrical power. In contrast, current U.S.
coal-fired power plants have an electrical efficiency of approximately
35 percent.

In addition, the envisioned SOFC-hybrid system is expected to capture
90 percent or more of the system's emissions of carbon dioxide (CO2),
the main greenhouse gas, while being cost-competitive with other
baseload power generating technologies.

FuelCell Energy, a fuel cell manufacturer based in Danbury, Conn., said
it may consider submitting the SOFC project for possible inclusion in
the FutureGen initiative, which calls for development of an integrated
coal gasification and power plant facility. In addition to gasifying
coal and generating electricity through gas turbines, FutureGen is to
produce hydrogen and strip out and capture CO2 and various pollutants
before they are discharged out smokestacks.

The consortium of coal and power companies developing FutureGen is
looking at sites in Ohio and Texas to build the facility.

The first phase of FuelCell Energy's coal-fueled SOFC project calls for
scale-up and performance enhancement of an existing 3-kilowatt SOFC
cell previously operated by the company for more than 2,000 hours, with
all performance goals for power output, durability and efficiency being
exceeded. The testing utilized the cell and stack design of Versa Power
Systems Inc., which is FuelCell Energy's technology partner on the SOFC
project.

The goal of the Phase I project is to test a stack building block unit
operating on simulated coal syngas, and to construct an 80- to
100-kilowatt capacity stack tower, comprised of these building block
units, to validate design components associated with a multi-stack
tower.

General Electric, which is leading a rival research team on the coal-
fueled SOFC project, recently announced it has developed and delivered
to DOE a 6-kilowatt SOFC prototype for use in the program. GE said the
prototype achieved an efficiency of 49 percent.
