And I reveal my scepticism: The current energy race is for more and cheaper solar, and for ways to store it. Since solar energy is intermittent, battery storage technology is growing to match. But also, splitting water molecules is one way to use that intermittent energy. As solar gets cheaper, splitting water molecules gets cheaper. I don't see any strong reason why the current energy race won't continue for the foreseeable short-term future, so there's no other "next energy race" coming soon.
