I'm not sure you're familiar with straw man arguments. I know the drawbacks of hydrogen, and for example, I don't think it makes sense for personal vehicles like cars. OP started a though experiment where we think of a new technology chain where energy is abundant and irregular. In this setup hydrogen might make sense because its energy intensive process is no longer an issue.
