Sustainable Hydrogen-Derived Heat System Could Transform Coal Power Plants

Australian startup Star Scientific has patented a new technology that transforms hydrogen and oxygen into a superheated steam used to generate sustainable energy. Unlike other hydrogen-derived heat sources that rely on burning hydrogen, this small lab uses an undisclosed catalyst that, when combined with hydrogen and oxygen, heats the mixture to 700 degrees celsius. At a large scale, this system—which apparently resembles a French press—could …
