Energy density is indeed it. Not much to argue about, it carries several times more energy per weight than any battery, and is several times cheaper too. The Mirai is a proof of concept, not a typical use case.
- SigmundA 5y agoWhen counting storage tanks, fuel cells, buffer batteries and protective structures no hydrogen doesn't really seem to have density advantage. The electrons in the battery are very light and energy dense but the battery to hold them and return them as useful current is not, same for hydrogen. What hydrogen fuel cell car is not a proof of concept?
