The Quest for ‘Hydricity’ - via @nytimes #hydro #hydropower

In the 1980s and ’90s, hydrogen fuel cell technology seemed like a strong candidate for use in cars and stationary applications, converting hydrogen to electricity with no emissions beyond a puff of antiseptic water vapor. Geoffrey Ballard , founder of Ballard Power Systems, coined a term to describe the new system, “hydricity,” a fusion of hydrogen and electricity. Surplus electricity could be used to split water molecules into hydrogen and oxygen, with the hydrogen stored for reconversion into electricity. Such a reversible system would be especially useful in cars, or in an electric system that was saturated with renewable power sources that ran only intermittently, like wind machines or solar cells. In 2008, the possibilities for fuel cells looked better than ever, when the nation elected a president who called for an 80 percent reduction in carbon dioxide emissions by...
