It's not like the alternatives don't have serious issues of their own. Inductive charging or power supply is lossy, H2 is /really/ good at leaking out of storage (and producing the stuff and compressing or liquifying it are all monsterously lossy processes). I went on a tour of Diamond a couple of weeks ago, and they were talking about recent work to zap their small particles at some molecular structures which Nottingham university is developing to store hydrogen. My brain was at risk of starting to hurt, but it sounded convincing at the time. People have been talking about that for years. ISTR (but it was a long time ago so I could be very, very wrong) reading of tests where bullets were fired through hydrogen adsorption tanks, the kind that were intended for motor vehicle use, to prove that they wouldn't explode. I remember seeing film of just such a test on Tomorrow's World about 40 years ago. What they don't show is that you can do the same through a petrol tank.
