    It’s where “green” hydrogen comes from — which everyone keeps promoting as the future. People claim “oh we can just split water using electricity from solar wind and nuclear”. Not considering that it takes a lot of energy to do that. Energy that you’d get better bang for your buck by putting into batteries.

      Oh. Well that’s a silly distinction of them to make. Hydrogen is abundant and refining processes are constantly getting cleaner, especially these days, no worries.

            That doesn’t mean it’s accessible to be put into fuel cells.

              Are you asking a question?

              Because the hydrogen I’m mentioning is accessible to be put into fuel cells.

                  Correct. That is where fuel processing comes into play.

                  For all fuels, let’s say gasoline for example, you can’t just grab a bowl of oil from a crude oil well and dump it into your fuel tank.

                  The fuel needs to be carefully refined and processed.

                  Same with hydrogen, same with biofuels, that’s how refined fuels work.

                    There’s no skipping thermodynamics, maybe there will be a technology for an arbitrary molecule to hydrogen gas reformation but it doesn’t exist to my knowledge. Electrolysis of water means breaking the bonds and that takes a lot of electrical energy.
