Article seems a bit confusing on what exactly they mean by “solid hydrogen”. It doesn’t seem like they mean actual, pure hydrogen frozen into a solid (not that that’s surprising, given how insanely cold that would need to be), but they keep mentioning a “solid fuel cell” of some kind without really going into much detail on exactly what that is.
Its clearly not solid hydrogen, but instead some room temperature stable ‘chalk-like substance’ that serves as a matrix for the hydrogen. Pretty neat if they can manage it as a battery tech and provided its not too explosive.
