On February 16, 2011, the Environmental and Energy Study Institute (EESI), House Fuel Cell and Hydrogen Caucus, California Fuel Cell Partnership, and Fuel Cell and Hydrogen Energy Association held a briefing about the status of commercial deployment of fuel cells and hydrogen. Fuel cells, which can be used as stationary power sources or to power vehicles, convert fuel and oxygen into electricity, with water and heat as the only byproducts. At this briefing, experts discussed the state of stationary fuel cell system, fuel cell vehicle, and hydrogen infrastructure development; challenges to wide spread deployment; economic and environmental benefits; and opportunities for industry and government to develop partnerships to accelerate commercial deployment across the nation.
