Hydrogen is the renewable fuel that could eliminate the biggest source of demand for fossil fuels—the transportation industry. It is the star in a script for a hydrogen economy built on electrolysis, the process that yields emission-free hydrogen fuel. And now, this script has come a step closer to reality thanks to a new material. A team of scientists from Northwestern University said this month they had developed an ultraporous material that can be used for storing hydrogen. Storage is one of the challenges hydrogen needs to overcome before becoming a mainstream fuel, and the NU material may go a long way towards solving this problem. The problem comes down to the cost and safety of storing hydrogen. The most abundant chemical element in the universe can be stored either as a compressed gas or as a liquid. Both methods are costly and, more importantly, they carry risks because […]
