High-pressure Compound Could Be Key To Hydrogen-powered Vehicles

A recently discovered hydrogen-rich compound may help overcome one of the biggest hurdles to using hydrogen for fuel -- namely, how do you stuff enough hydrogen into a volume small enough to be practical for powering a car? The newly discovered material is a form of ammonia borane. Working at high pressure in an atmosphere artificially enriched with hydrogen, the scientists were able to ratchet up the hydrogen content by roughly 50 percent.
