    It isn’t. The amount of green hydrogen is a fraction of a fraction a percent of all hydrogen. The rest is all made from natural gas and the CO2 is released into the air. It’s a green washed fossil fuel.

      “Green hydrogen”, is also incredibly inefficient in its own right. Approximately a 70 percent loss of energy compared to 15-20 percent for battery storage. It would literally be just as efficient to burn natural gas in a power station (with a 50+ percent efficiency, modern power turbines are very efficient) and use that power to charge a battery. The entire “hydrogen economy” has been a pipe dream by either complete morons or fraudsters (probably both). (Hydrogen aeroplanes might actually work, but that is by combustion and jet engines are already very efficient).

      But if they’re making the stations, they can use or manufacture green hydrogen. It just a matter of the political will.

        But they’re not. See: this article. They’re not profitable, and if they ever were, it was propped up by greenwashing a byproduct of natural gas production.

          The article didn’t link. Also, not profitable compared to what? Because running at a slight loss to decrease ghg emissions would still be worth it. Are there fully electric battery alternatives to use instead?

            I’m referring to the article posted in this post. Stations are being shut down because they aren’t profitable. It doesn’t have to be compared to anything. If they can’t make hydrogen cheap enough, they can’t sell enough and they can’t sustain the business mode.

            The cheapest way to make hydrogen now is as a byproduct of natural gas production which is not as eco-friendly as anybody would hope.

            Hydrogen for consumer use is a boondoggle and waste of time. BEVs are here and work great on existing infrastructure (for L2 charging at least). I drive an EV and exclusively charge it at home. No special station required.

              Absolutely. That’s what I said originally. Consumer use never made sense. But busses or trains might still make sense since they’d have much more centralized infrastructure.
