      They’re reusable and we don’t have a problem with 5 gallon propane tanks so I don’t see why these gas cylinders would be worse.

        Hydrogen. I don’t know how Toyota has handled it and didn’t read the article yet, but those molecules are so tiny they get into everything and cause problems.

        Edit: Article says nothing of use on the subject, and it sounds like this is at the concept phase anyway, so it’s probably vapourware.

            Hydrogen gas is H2, so I think it technically is a molecule, since it’s not hydrogen ions

              Yup. The atoms are also small, for whatever that’s worth.

              Not sure why I got downvoted. Presumably people here are nerdy enough to know hydrogen isn’t a noble gas and doesn’t hang out as a singlet.

                doesn’t hang out as a singlet

                Technically, since the two electrons in H2 are paired in the ground state, s = 0, which is the definition of a singlet :)

                  Oh no, has an actual chemist appeared?

                  I have yet to learn much about the exact physics of bonding.

                    Maybe :)

                    In chemistry, a singlet refers not to a single atom, but to a configuration with equal numbers of “spin up” and “spin down” electrons. This is the case for the ground state of many molecules (such as H2), but not all molecules. O2 is probably the simplest and most well-known example, with the electron configuration being most stable in the triplet state.
