Bloom Energy: solid-oxide fuel cells

Bloom Energy aims to give the world independence someday from power grids and gas stations. It builds what are called solid-oxide fuel cells, in which water, oxygen, and a hydrogen source such as natural gas are pulled through the cell to cleanly generate electricity. One of the byproducts of the process is hydrogen, which in turn can be used in a different type of fuel cell: the hydrogen-powered version imagined for propelling cars of the future. If Bloom’s technology fulfills its potential, homes and businesses could one day generate their own electricity and fuel their own vehicles. (Business Week) (U of Tenn. Trial)
