An Inexpensive Fuel-Cell Generator

A startup says its technical advances could make fuel cells as cheap as grid power.

People could soon get cleaner energy from a compact fuel-cell generator in their backyards, at costs cheaper than power from the grid. At least, that’s the hope of Redox Power Systems, a startup based in Fulton, Maryland, which plans to offer a substantially cheaper fuel cell next year.

Redox is developing fuel cells that feed on natural gas, propane, or diesel. The cells, which generate electricity through electrochemical reactions rather than combustion, could allow businesses to continue operating through power outages like those caused by massive storms such as Hurricane Sandy, but they promise to be far cleaner and quieter than diesel generators. They can also provide continuous power, not just emergency backup power, so utilities could use them as distributed power sources that ease congestion on the grid, preventing blackouts and lowering the overall cost of electricity.
