Hydrogen-powered cars sound like a great idea, but how do you stuff enough hydrogen into a small, portable volume that’s practical as fuel? Help could be on the way in the form of a hydrogen-rich compound discovered by researchers in the Stanford Institute for Materials and Energy Science at the Department of Energy’s SLAC National Accelerator Laboratory.
The newly discovered material is a high-pressure form of ammonia borane, a solid material which itself is already imbued with ample hydrogen. By working with the parent material at high pressure in an atmosphere artificially enriched with hydrogen, the scientists were able to ratchet up the hydrogen content of the material by roughly 50 percent.
