Study shows a much cheaper catalyst can generate hydrogen in a commercial electrolyzer

Researchers at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have shown for the first time that a low-cost, non-precious metal cobalt phosphide (CoP) catalyst catalyst can split water and generate hydrogen gas for hours on end in the harsh environment of a commercial device. Electrolysis works much like a battery in reverse: Rather than generating electricity, it uses electrical current to split water into hydrogen and oxygen.
