Never mind that in order to be in usable form, hydrogen must be released from whatever molecule it is covalently bonded to, and that it takes at least as much energy to break those bonds as is returned by burning the hydrogen to reform bonds later on.
Those little physics based drawbacks of hydrogen usage are the reason that the hydrogen fuel cell fad of the 90s never really caught on (except briefly among those who don’t understand physics).
We all miss the point that those smarter than us are on the brink of producing the perpetual energy machine. Just a few more government grants and they’ll work out the kinks.
Yes, which is why when someone says “hydrogen power”, you know they’re clueless. E.g. George Cluny when he was pretending to be a politician in some movie I recall.
