Sustainable Hydrogen-Derived Heat System Could Transform Coal Power Plants

Link — Tech

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 …

A Battery Powered by Bacteria and Sweat

Link — Tech

Researchers from the University of Massachusetts Amherst have engineered a bacteria-based battery that can produce power from human sweat. The key to their innovation is bacterium Geobacter sulfurreducens, a bacteria that can produce electricity and has been used to explore microbial batteries. However, its need to be fed a constant diet has limited its functionality. To get around this, the researchers grew the bacteria sustainably …

The World’s First Sand Battery Debuts in Finland

Link — Tech

As fossil-fuel-derived energy systems facilitate the degradation of the planet, researchers have been innovating alternative and sustainable solutions—including the world’s first sand battery from Finnish startup Polar Night Energy. Currently operating in Finland’s Kankaanpää district, the battery relies on a large steel tank full of regular, dry sand with a heat exchanger buried in the middle. When the sand is heated, the tank can store …
