Taft joined governors from Maryland, Connecticut and Pennsylvania in a joint statement on Tuesday. Congress is considering tax credits for fuel cell projects in the National Energy Policy Act of 2005, a pending bill.

Although still experimental, fuel cells are intended to produce cleaner energy than traditional power plants. Fuel cells extract electricity from fuel through a chemical process, whereas traditional power plants burn fuel to extract energy.

Fuel cell technology makes up a major portion of the state's Third Frontier project, a 10-year, $1.1 billion program to spur high-tech business in the state. The Third Frontier established a $100 million Fuel Cell Initiative to give grants and loans to businesses and institutions researching fuel cells. The city of Westerville and AMP-Ohio, an organization of municipal power companies, established a fuel cell demonstration project in November that is intended to power as many as 180 homes.
