The catch is that hydrogen storage is the smallest of the problems facing the nascent hydrogen economy. Energy losses in electrolysis and in the conversion from hydrogen to electricity are by far the biggest piece of the efficiency-loss pie.
- cbmuser 4y agoElectrolysis is only one method to make hydrogen. Another one is using high-temperature reactors which have a much higher efficiency and don’t need as much energy. Research on the matter is being made in Japan, see: > https://www.jaea.go.jp/04/o-arai/en/research/research_03.html https://www.jaea.go.jp/04/o-arai/en/research/research_03.htm...
- causality0 4y agoElectrolysis efficiency is 76%. What sort of numbers are they getting with this high-temp reactor doohickey?

- jerome-jh 4y agoHydrogen storage is certainly not the smallest problem we face with hydrogen fuel. Di-hydrogen is a very small molecule that is hard to contain. It requires very tight seals. Not technically impossible, but very costly at large scale.
