Reply to comment by [deleted] in Rolls-Royce successfully tests hydrogen-powered jet engine by je97

Actually it's incredibly energy intensive, so 'easy' is misleading. That's only one of the very major problems with hydrogen as a fuel. Electrolysis of water consumes more energy than combustion of hydrogen releases.

That's why it wouldn't be useful for power generation for a country, but as a fuel for discrete things like jets. Renewables like wind and water, and nonrenewables like fission should make up the difference. And, if we can ever figure out fusion, we could get nuclear power out of water too.

It took more energy to make Petrol than you get out of it too. And it takes millions of years to make it at that.
