Fracking Hydrogen From Rocks: Clever Tech, Tough Economics

11 min read

Engineered mineral hydrogen is an elegant idea. Water reacts with iron rich magnesium and iron rich, silica poor igneous rock — ultramafic — from Earth’s mantle rocks to release hydrogen, and with the right chemistry and temperature you can raise reaction rates and collect a clean product. In the lab … [continued]
