Can be from solar cells, the cheapest option today.

  Green hydrogen (from renewables) is not the cheapest option to my knowledge. In fact it is not yet cost-competitive. The electrolysis process is not still efficient today (but improving) and does not yet have scale, and the cost is several times SMR-produced hydrogen. Most economical hydrogen is produced through SMR or as a byproduct.

    That could be true, but the question was > From what I’ve read, liquid hydrogen isn’t a great option due to the energy required to create it. Where does that energy come from? and to get the cheapest energy, not the cheapest hydrogen, today one would surely consider solar. Having said that, hydrogen could be interested as more ecology friendly fuel, which may rule out the commercially cheapest, but not clean enough, options.
