Scientists from Victoria’s Monash University claim to have made a breakthrough that will bring the inexpensive industrial production of green hydrogen from Australia’s abundant renewable energy generation resources much closer to reality. The research, which has been described as “critically important” to Australia’s shift to renewables, identifies a variation on water splitting technology, or water electrolysis, that would give it “unparalleled stability,” without blowing out costs. Simonov told RE in an interview, the state of the art material used to split water into oxygen and hydrogen has been iridium oxide. But this is one of the rarest elements to source, he says, and still isn’t entirely stable. “Our research team has introduced an intrinsically stable, ‘self-healing’ catalytic system based on earth abundant elements to promote the water electrolysis process in a strongly acidic environment and elevated temperatures.
