Reply to comment by Alis451 in Overhyping hydrogen as a fuel risks endangering net-zero goals by filosoful

A firm called Plasma Kinetics has been operating a long time. They worked out how to store 1H as a solid, and have stored it on disks. they are already involved with the automotive industry also.

I think we'll see a shift away from what everybody thinks about 1H storage.

MgH2, Magnesium Hydride was the last solid hydrogen storage medium that I saw they were working on. The problem is that it is solid, which makes it a terrible refueling storage medium, you need a liquid(like gasoline) or a gas that can be safely condensed(like propane), solids are difficult to extract the energy back out from, though not impossible, especially if they sublime under heat or are able to be activated while in a solution.

Palladium is also a fantastic Hydrogen storage device, with being able to store up to 900x its volume in hydrogen or something like that, palladium is already expensive for its unique properties and uses in catalytic converters.
