Haven't tried it in practice though, so if you have, let me know.
I haven't worked out the energy you could store as H2 in a scuba tank, just did a "back of the envelope" calculation of the weight of H2 vs tank weight. But that leads to another interesting question: figuring all the various ineffiencies in getting energy in and out, would it be more weight-efficient to store energy as H2, or as electricity in a lithium battery?
