Shell Is Immediately Closing All Of Its California Hydrogen Stations | The oil giant is one of the big players in hydrogen globally, but even it can’t make its operations work here.::The oil giant is one of the big players in hydrogen globally, but even it can’t make its operations work here. All seven of its California stations will close immediately.

    They make solar stations that will pull hydrogen right from the atmosphere. What carbon are you talking about…and you do realize the same power that would be used to make hydrogen in your example would also be charging batteries.

      Hydrogen isn’t in the atmosphere. The atmosphere is 20.9% oxygen, 70% nitrogen and some trace other gases, none of which are hydrogen.

      Hydrogen is produced either by splitting water (the H in H²O) or splitting hydrocarbons like Methane which produces CO² (the carbon part bonding with oxygen from the atmosphere, making that stuff we’re trying to cut back on).

      That second method is why the fossil fuels companies are so keen on it. Hydrogen can be a repacked form of natural gas.

        Yes totally forgot how there is no water in our atmosphere…forgot the globe just has water in a few places and humidity doesn’t exist…

          Oh yes, that 1% water vapour (on average) that you want 2/3rds of.

          Gimme a break. I don’t think your machine producing hydrogen “straight out of the atmosphere” is going to be fueling many cars.

      That is a waste of solar. It’s more efficient to put in batteries then kinetic. If there is no more batteries to put it in, you transmit the power over wires.

      With hydrogen it’s wasteful to create from electricity, then wasteful to turn into kinetic. Its wasteful to store as it’s the smallest atom so escapes easily, it’s low density so needs compressing. Then, to move it, you have to move storage around instead of just transmit over wires.

        A…waste of solar…internal ICE hydrogen motors is what these would be used for not fuel cell hydrogen.

        How are you wasting solar? Lol this makes no sense. These can be stood up anywhere, you cannot use these as super chargers for batteries…

          Look at the efficiency of the energy conversions. It is literally wasting solar.

            How is it wasted if it completely free energy? You cannot charge up electric cars quickly via solar…hell solar in general isn’t super efficient anyways lol

              No energy is free because there is always installation and maintance cost. Lot’s of people change their cars off solar. Most of a car’s life is sat parked for hours. So slow is fine. My charger has a solar divert function I’m yet to get the solar for. Also, you change a house battery slow and then a car fast from it. Even here in the UK there are people doing it. Not solar all the time, but a lot in summer. House battery changed when your in the office, car overnight from that.
