Storing energy in hydrogen 20 times more effective using platinum-nickel catalyst

Catalysts accelerate chemical reactions, but the widely used metal platinum is scarce and expensive. Researchers have now developed an alternative with a 20x higher activity: a catalyst with hollow nanocages of an alloy of nickel and platinum. Researchers want to use this new catalyst to develop a refrigerator-size electrolyzer of about 10 megawatts in the future.
