GM and Dow step up testing of hydrogen fuel cells

November 30, 2004

General Motors Corp. expanded a hydrogen fuel-cell test with Dow Chemical Co. as the companies seek to develop low-pollution power systems for vehicles and manufacturing.

The project's single test cell is converting to a plant with multiple fuel cells at Dow's factory in Freeport, Texas, the companies said Monday. The plant will supply energy for Dow's Texas operations. GM and Dow are seeking to demonstrate the reliability of fuel cells, the companies said.

GM and Dow said, if the Texas expansion succeeds, the project would begin to build fuel cells for commercial sale by 2007. The companies would install as many as 400 fuel cells at Dow plants. The dishwasher-size fuel-cell units create electricity by combining hydrogen with oxygen in a chemical reaction that under ideal conditions emits water vapor.

U.S. automakers are under regulatory pressure to manufacture cars that generate less pollution. GM is trying to reduce the cost of fuel cells. A unit large enough to run a car is about 100 times more expensive than a gasoline engine producing the same power. Fuel cells have been used for decades in spacecraft.

The pilot plant will have four fuel cells at the start with additional cells added during 18 to 24 months, Gina Gibbs Foster, a Dow Chemical spokeswoman, said in an interview.

The Detroit automaker owns and operates the fuel cells, and Midland-based Dow will pay an undisclosed amount for the electricity. Hydrogen gas emitted by the Dow factory as a by-product will be used for the fuel cells.

GM shares fell 40 cents to $38.83 and Dow rose 38 cents to $50.80 on the New York Stock Exchange.
