    You store hydrogen in underground salt caverns on the large scale. Similar to how natural gas works. Above-ground tanks for local storage, and move via pipelines for the most part. It is not a perfect replacement for gasoline, but it is close enough.

    The reason why you reuse gas stations because that’s what’s actually happening. Hydrogen stations are just converted gas stations in most cases.

      Where on earth do you think your local 7-11 is going to come up with underground salt caverns?

      We don’t even have pipes for gasoline and it doesn’t soak through steel. Nobody’s paying to dig up all the roads and footpaths necessary to build hydrogen pipelines across town and replace them when the hydrogen turns them brittle.

        Local hydrogen stations will probably use above-ground tanks.

        Hydrogen pipelines are 10x cheaper than wires. It’s not some inconceivably huge cost.

        It should be added that environmentalist have been screaming for massive investment in green energy, and that cost is of secondary importance. We shouldn’t suddenly become hard-right conservatives here. As long as costs are reasonable, it is fine.

                  For economic reasons, it is much better to transport energy over long distances by molecules. When you transport hydrogen over a distance of about a thousand miles by pipeline, the costs are about half a cent per kilowatt-hour. When you do the same with electricity, it is about 5 cents per kilowatt-hour.

                  This all you’re talking about? Unquantified speculation from a guy trying to sell hydrogen? Don’t thank me for playing dude, find another game.

                    He’s spent years of his life researching general green topics and has a Ph.D. If you won’t listen to him, then there’s no one you will listen to.

          Wasting 2/3 of the energy we generate by turning it into hydrogen and back isn’t a green solution. It means we need to triple our electricity generation and keep coal and gas plants running for a lot longer.

            Funny how the 20% efficiency of photovoltaic panels never bothered you.
