is the answer. Hydrogen fuel cells are about 95% efficient. Hydrolyzers are improving in efficiency at a rapid pace. What about storage? A research institute in Dresden, Germany, has developed hydrogen paste. It’s created by mixing magnesium and hydrogen, along with a small amounts of a couple other chemicals, at moderately high temperatures. The paste is then mixed with water to release the hydrogen. The paste has the consistency of a watery toothpaste.

So how do we generate the hydrogen? Electrolysis using green electricity.
