US start-up Electro-Active Technologies has licensed its refinery technology, which converts food waste into renewable hydrogen gas. Electro-Active's method uses microbial electrolysis to break down the waste and efficiently extract electrons, before a second process combines them with protons to produce hydrogen. The firm is developing a prototype, modular system which can be deployed to customers on site.
