    japan has this problem as all of its automobile companies decided to invest down the path of hydrogen (as it fit their home country/interests better) over the rest of the worlds EVs. because of it, japanese fully EVs tend to be kind of lackluster, because theyre usually second thought.

      its automobile companies decided to invest down the path of hydrogen

      The Japanese government invested in hydrogen, with R&D grants. It was a huge fail.

      Then, Toyota stockholders kicked out Toyoda because he said there was no market in EVs. He was right, Toyota is ruling sales with hybrids and PHEVs. Unlike Tesla, Toyoda needed Toyota to make money selling cars, not conning an investor cult.

      I don’t understand how anyone anyone thought or thinks it could be better to use electricity to pull hydrogen from water, then turn it back into water to get electricity again, with energy losses of 40-60%. Not while you could just keep the whole chain as electricity, with losses of ~10%.

        It’s designed to greenwash natural gas. The petroleum industry threw their weight behind it because you can make hydrogen from methane.

          There is the theoretical advantage of storage.

          Storing HYDROGEN is an advantage? The thing where the atoms are so small, it diffuses through the walls? The thing that needs insanely high pressure containers? THAT should be an advantage? WTF?

                Hydrogen fuel is in a compressed, liquid form that quickly vaporizes if exposed to air.

                Gasoline also vaporizes but much, much slower and isn’t stored.

                There’s a lot more involved with keeping a gas in liquid form than something that’s already liquid at normal atmospheric pressure.

            Don’t forget hydrogen embrittlement which means the entire fuel system must be replaced every so many years.

            Did you miss the word theoretical? And yes, AFAIK we are already storing some but certainly not at the scale required if that’s even possible (I wouldn’t want to live anywhere nearby a huge storage of hydrogen). Another related advantage would be the transport of stored hydrogen where transferring electric energy comes at cost when it comes to long distances.

              No and there is no theoretical nor a practical advantage. Throwing in the word “theoretical” to make a wrong idea sound valid doesn’t work with me.

              Another related advantage would be the transport of stored hydrogen where transferring electric energy comes at cost when it comes to long distances.

              A gasoline range extender makes more sense than hydrogen.

                Gasoline in the EV? That is the worst combination. Also we are storing hydrogen today, so it works to some degree.

                  No true. That’s way more efficient than hydrogen and the gasoline could be substituted by ethanol.

                    Hybrids are perhaps worse than both ICE and EV. More complex, burns more than the other two, still consumes a shit ton of oil and pollutes a lot. Ethanol has also its problems, like how does one get it in enough quantity. Why do you think we are not driving ethanol cars today?

        Japan’s electrical grid is pretty outdated and has been pushed to it’s limit. It simply cannot support an influx of EVs. That’s why the government has been pushing hydrogen, which can be produced from electricity like you said, but is “better” produced from natural gas or coal, which they have easy access to. It’s a terrible solution to the problem.

        Hydrogen also solves the range anxiety issue by being incredibly energy dense, with the minor downside of occasionally exploding.

        You loose ~50% of electricity in transport.

        Hydrogen isn’t great, but synthetic methane is much more efficient to store and transport

            Also degraded batteries can be reprocessed into fresh batteries again, we will only need to mine a lot of them when growing, once the batteries are made we don’t need to mine as much.

      It’s only Toyota who went deep into hydrogen. Even then they have 1 model, the Mirai, which is horseshit even without taking the infrastructure problem into account (which should absolutely be taken into account). They sold like dozens. It was a fairly transparent anti-EV deflection. None of the other OEMs made serious foray into the tech, though some did pay it lip service (for the same reasons).

      Also importantly, hydrogen doesn’t suit Japan any better than anywhere else. They have zero production capability and the import route is an oil exec’s fever dream

        Oh no, Honda has been talking up Hydrogen just as long as Toyota. Toyota has the Mirai, Honda has the Clarity.

        Both companies seem to be stuck going for it for whatever reason though. Hydrogen vehicles are literally more complicated EVs, still use a highly combustible fuel, need even more safety systems than gasoline to prevent fires and explosion at the fueling stations, and the large tanks naturally leak because hydrogen is such a damned small atom that it literally sublimates through the skin of the tank. Hydrogen fuel cells are used to generate electricity for standard electric motors. There is literally no good reason for it with battery technology advancing as it has the last decade.

        Meanwhile a BEV can be slowly charged from any standard outlet, and very quickly at dedicated chargers. As quick as an 80% charge in 10 minutes from the cutting edge Chinese batteries and chargers. And that doesn’t even get into people being able to charge overnight at home and rarely needing to visit a dedicated charger at all.

        Hydrogen makes no sense in any situation with modern battery tech anymore. But for some reason both Toyota and Honda keep trying to beat that damned horse to oblivion.

        it suited japan better because japan doesn’t remotely have the capacity to be making batteries. something china has a huge grapple on. It’s governement when to push its basic hydrogen strategy and it keeps pushing for it if you read japanese headlines.

        Toyota, Nissan and Honda literally are in consortium for hydrogen mobility

        It was a fairly transparent anti-EV deflection.

        The entire drive train is electric, though. Nobody really does hydrogen combustion (I think it’s the nitrogen in the atmospheric air that reacts with the hydrogen to make poisonous gas.)

        Taking the drivetrain seriously would mean improvements to all cars with either kind of energy store.

      I don’t think I’ve seen a single hydrogen station or vehicle here in Japan.

      Apparently there’s ~150, for a country of 125m.

      The main issue from what I hear is that they realy though hybrid would be the perfect middle ground, hence why every vehicle they both had was hybrids.

      And those should have been easy to move to fully EV when they saw that was the way forward, but apparently they didn’t see that, so kept on with the hybrids.

      [EDIT] noticed from the reply under that i forgot to add Toyota on this. that is what i ment by “both”: Toyota and Honda.

        Who’s “they”? Cause other than Toyota, the rest of them didn’t even care about hybrids until very recently.

        But yeah, Toyota really dropped the ball after being the defacto leader of hybrid tech for so long.

          Honda has been selling Hybrids since atleast '99, when they came out with a hybrid right before Toyota came out with the Prius.

          for a while they have had Hybrid version available for most of their car models.

            Not really. The Insight was a gutless two seater designed for CARB compliance. You couldn’t even buy one at most dealers.

            Toyota Prius was the first serious hybrid. They sold over 6 million of them. Honda sales were 1/25th that.

            Ah I stand corrected. I see they never sold them globally outside the local & American markets. And eclipsed by Toyota by about 20x.
