Once upon a time, hydrogen was supposed to be the future of energy. In 1845, English scientist Sir William Grove (aka “the father of the fuel cellâ€) demonstrated that, given the right conditions and the addition of oxygen, hydrogen gas — also called H2 — can undergo a chemical reaction and produce a potent, and non-polluting, electrical punch. The possibilities for hydrogen power seemed endless: it could fuel our cars, heat our homes, and even power our airplanes. But today, 175 years after the creation of that first “gas battery,†the technology has yet to reach its full potential.
