SOLAR-POWERED HYDROGEN FUEL
We're One Step Closer to Creating Hydrogen Gas from Solar Energy; Solar panels of the future could produce clean-burning hydrogen gas in a one-step process.

“…[O]ne the biggest questions facing the solar power industry…[is how to] get a solar panel to supply a reliable, steady supply of electricity…[Scientists] and engineers are increasingly…using solar power to create clean-burning hydrogen gas…[which] can be stored indefinitely, and has the highest energy density of any gas or liquid fuel…[A team of researchers at the University of California, Berkeley] has taken a large leap toward developing efficient solar fuel cells that transform normal water into hydrogen gas…[using a new, metal-based material to make] solar fuel cells. These fuel cells—in a one-step process—would split apart an incoming flow of liquid water into steady streams of oxygen and hydrogen gas, with nothing more than a gentle influx of sunlight…[In solar fuel cells, the] anode side rips oxygen from water in a process called solar electrolysis, and the cathode side produces the flow of hydrogen gas…Even with the new material, hydrogen-producing solar fuel cells are still too wasteful and far from commercially viable…[but provide a] conceptual framework for developing even better anode materials…” click here for more
