Nobody is saying that hydrogen technology is without its problems, but it is feasibly scalable unlike anything else I am aware of, and it is not some kind of mythical vapourware that exists only in the form of CAD renderings.
Over time, hydrogen damages the tank. (Which is undesirable combo with “explosive gas when mixed with air”)
I would like some breakthrough in material sciences here.
> Steel with an ultimate tensile strength of less than 1000 MPa (~145,000 psi) or hardness of less than HRC 32 on the Hardness Rockwell Scale is not generally considered susceptible to hydrogen embrittlement.
https://en.wikipedia.org/wiki/Hydrogen_embrittlement
Gas storage facilities also generally use geological structures which are not susceptible to hydrogen embrittlement either:
Converting hydrogen into something more safe, like ethanol or methanol. Fuel cells for those also exist, but needs more research.
Is there somewhere to learn about the proper storage and use of hydrogen?
I’d just add that for grid scale storage the hydrogen probably doesn’t have to go far from generation. That probably resolves plenty of problems.
