Comment on Stellantis abandons hydrogen fuel cell development

  Hydrogen does not have to be a byproduct of petroleum production, you can drill just for hydrogen.

    Are there even any natural hydrogen deposits on earth?

    Every plan for green hydrogen I’ve seen so far relies splitting water via electrolysis.

      Natural hydrogen deposits do exist, but they’ve only been mapped out quite recently and it is still unknown if it can be extracted in a safe and economically viable manner.

      Yes! Although it’s a relatively recent discovery.

    Hydrogen gas is produced by several industrial methods.Nearly all of the world’s current supply of hydrogen is created from fossil fuels.[2][3]

    We’ll see.

    Once there’s enough hydrogen drilling and hydrogen production no longer depend on fossil fuel, then maybe H2 vehicules will make sense. Or maybe H2 will still be impractical due to other drawbacks.

    Meanwhile it make sense to focus on less polluting options.

      Oh great, punch more holes through the aquifer that can’t be repaired

      Theoretically one can slap a shit ton of solar panels to produce H2 with excess energy. Not very efficient, but still very green.

    to date there is zero evidence of meaningful deposits of geological hydrogen. There is definitely hydrogen in the crust, but, so far zero evidence that it accumulates in meaningful amounts in the areas we can currently drill to.

      lol my wife literally was the project manager for a hydrogen site in Arizona. No clue where you got your information, but it’s just absolutely incorrect.

        The United States Geological Service.

        A pocket producing an amount is not the same as a significant deposit.

    Also it seems to be a good energy storage…for cases where you have irregular energy production. Create hydrogen via electrolysis using the energy surplus from wind, photovoltaic etc.
    And if you need the power, you get it back via fuel cells.

    I think I saw a documentary about the shetland islands, where they have (or had) a power surplus from wind farms mich grater than they where able to transfer to the main land.

    I guess these are the cases which make sense…but creating another supply network to bring the hydrogen fuel everywhere might not be the way to go…

  ? You can get Hydrogen through simple water electrolysis. In fact you can do it at home. That’s like how 4% of all hydrogen is manufactured.

  • Midnitte@beehaw.org ⁨1⁩ ⁨month⁩ ago

    You may not realize this, but 4% is not most.

    You should also ask yourself how most of the electricity is generated to electrolysis the hydrogen.

      You didn’t say “most” on your original post. You might want to edit it if that’s what you meant.

        I suppose that’s fair, but given the context, an insignificant amount of… still not green hydrogen is sort of irrelevant

    It takes more energy than it’s worth.

    The infrastructure isn’t there, and hydrogen is more dangerous than gasoline if it leaks.

      I’d love to see a source on that.

      This Report by the US department of energy says otherwise.

        My chemistry lab experiment. 😅

        Spicy gas go boom.

        I suppose a slow leak wouldn’t be thay bad though. A catastrophic failure from a collision would be not great.

    Yet, for these facilities to be economically feasible, they need to run 24/7, not just when there is an excess of electricity available.

  I mean, there’s also white hydrogen and blue hydrogen, and other paths to green hydrogen than electrolysis.

  We still will have to figure out the hydrogen economy, if only for steelmaking and similar.
