    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.

                    This guy? https://www.hydrogeninsight.com/policy/prominent-advocate-for-hydrogen-heating-has-been-secretly-receiving-money-from-gas-network-trade-body/2-1-1418519

                    It’s alright, he says the funding he received from the gas network hasn’t influenced him so it must be true. Weird that he forgot to mention it in all of his papers, though. It’s just a coincidence that his funding comes from a group that’s counting on hydrogen to keep their business and existing infrastructure profitable in the future.

                    Personally I think we’re gonna experience societal collapse before we get to the point of replacing our fleet of vehicles with electric, let alone hydrogen. I love Green alternatives, but cars in general will be our undoing, not our saviour. I would suggest putting your energy into something constructive, instead of leaving 30 comments on a subject you might have studied and forgotten a lot about, but are still inept in.

        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.
