This hydrogen storage ‘sponge’ could be the key to safer EV fuel cells

A group of scientists claim to have made a breakthrough that addresses one of the biggest challenges associated with hydrogen cars. It could make hydrogen electric vehicles (HEVs) safer and give a significant bump to the distance they can travel on one tank. Researchers led by scientists from Northwestern University, Illinois, say they have developed a metallic sponge-like material that’s capable of storing greater quantities of hydrogen at much lower — and safer — pressures when compared to conventional tanks.
