Do you want to be the next Uncle Bill? Money mouth

If you can turn Solar Energy directly into Hydrogen Gas, then you are the next Uncle Bill. Money mouth

  • Hydrogen is a dead end. The only reason it existed in the first place is so that petrochemical companies hoped they could retain some of their distribution / sales pipeline.

    It's also dying out already. Back in 2011 there were 14 places in there UK where you could fill up your hydrogen car. In 2023 there were 11 (with only 8 available to the public). Now there are 6.

    Over that year, whilst hydrogen went from 11 to 6, public EV charging points went from 38,972 to 57,290.

    I think I agree apart from maybe some special bulk applications like steel making.

    But solar power could be used to make methane and synthetic fuels which we could distribute and use in our existing infrastructure. In the UK we might do better with wind power.

    Wind and solar have the same issues of intermittency but transforming the energy into chemical fuel makes it possible to store and efficiently distribute. So far we have two ways of doing that, batteries - which are inefficient in terms of cost to make, time to change and low energy density and combustible fuels which are inefficient in terms of use of energy to make them from atmospheric CO2.

    (I'm being a little flexible here in calling batteries chemical fuel but I think its OK in this context.)

    So we need a breakthrough - better batteries or better electricity to fuel conversion - either will do.

    I disagree, Hydrogen is the fuel the universe uses.

    EV sales are near zero in rural areas and dealers cannot sell the cars.

    It will take less effort to create a hydrogen fuel capability than it will to completely redo the electric grid to support EVs.
