With government entities rolling back EV regulations, now is the time to take a second look at hydrogen.

    I used to think it was the future. But I realized it takes too much electricity to create hydrogen.

    Better, solid state batteries are the future.

    Better yet, widespread electrified mass transit is even better.

      It takes the same amount of electricity in theory. Even in practice it is not a major issue since an all renewable grid needs energy storage, such as hydrogen based energy storage.

      A lot of wind energy is wasted when there’s “too much” wind and it there’s too much energy to feed into the grid. From I understand, it would destabilise the grid. At the moment, that energy goes nowhere - and it’s a lot. That could be used to generate hydrogen instead.

      Hydrogen is great for storage. It could also become the future for planes are it has more energy than kerosene, however no jet engines exist that can take advantage of it due to a lack of investment (which is changing rapidly). It is also lighter than kerosene, which would allow planes to fly longer or use less fuel to fly.

      Finally, electrolysis is also used to generate deuterium/heavy water, which is critical for nuclear fusion. If we ever invest as much in nuclear fusion as we did in photovoltaic or even combustion engines, generating enough energy to reach a 1 on the Kardashev Scale might actually be possible within our lifetimes.
