I have seen some who are very pro-hydrogen claim that using hydrogen metal hydrides allows for safe storage and use. Can any of the more engineering astute comment on that idea?

That is a decent way to actually store energy, but as with a battery the issue is "store" there; you're producing nothing. Where's the production come from?

To be fair a LFTR isn't 'free' either, but it DOES exploit E = mc^2 and since "c" is such a HUGE number you get a god-awful amount out of "E" for every bit of "m" you convert. But make no mistake -- there really is mass converted; it is NOT a free lunch.

The problem with hydrides is that they really aren't much better on an energy density basis than a lithium-chemistry battery. Which is dogshit, I remind you, compared with liquid hydrocarbons.
