Hydrogen as a storage in vehicles is stupid just from the energy density and efficiency point of view. Nevertheless everything else involved. To run a hydrogen-electric car, you get some best-case efficiency of around 20-30% of the power from the electric power plant, which means wasting as much energy as on internal combustion engine cars. A similar figure on a battery-electric car is 70-80% efficiency of powerplant to moving the car. The electric car itself is also much more energy-dense and allows for bigger power.

This basically means the hydrogen-electric cars will within the next quarter century be viewed like steam powered cars are viewed now; by far long obsolete and impractical.

Well that's your opinion, such that it is, who knows what informed it.

The thing is, China, Korea and Japan disagree, and are all going full in with hydrogen tech, building "Hydrogen Cities" and "Hydrogen Corridors" - part of Made in China 2025. You've heard of that, right?

Furthermore, even if you were right (you're not) hydrogen is powering drones, submarines, trucks, ships, trains and forklifts, all today. So cars are just one segment of the future of H2.

Far from "obsolete and impractical", hydrogen is an essential part of the green transition.

Well that's your opinion

It's not an opinion and your poor attempt at appealing to authority in form of false claims of China, Korea and Japan planning on hydrogen economy or your appeals to emotion won't save your argument. Battery explosions are also a small fraction of car fires, much more likely a gasoline car suddenly goes GTA/Hollywood-style BANG while driving, which in themselves are classified as freak accidents. However, a normal gasoline powered car just went into flames when it drove into the curb last night 100m or so from where I live. Hydrogen-powered cars will flame up easily, because hydrogen is leaks from the tanks and is a very inflammable gas.

Wrong once again. Where do you get your facts, from sites like electrek or "clean"technica, both owned by TSLA longs? lol

See ya at the 2020 Olympics, which will highlight Hydrogen.

Hydrogen is here now, whether you like it or not. You have just begun to hear about it too. And there's not a damn thing you can do about it, except maybe bitch on H2 threads.

We should have some remindme-bot here to see who's right within let's say 2 or 5 years, since it's been like this for about 20 years already, with hydrogen fuel cells "coming soon", yet never come, and battery-electric vehicles have become super common since then, and hydrogen cars are not. You just might be too young to remember/know it's been like this for a good while.

I'm confident even Toyota as one of the last players of hydrogen cars will end their silliness once they can't compete with battery-electrics from all the other manufacturers. To me, it seems like some indefinite excuse to continue production of internal combustion engine cars.

"Confident" or not, it's almost as if you simply cannot process what this guy is saying

Of course it does, because you know nothing about today's hydrogen industry. Even if hydrogen cars vanished tomorrow, there are hydrogen drones, trains, trucks, forklifts, ships and more. You have just begun to hear about it. Or, you could plug your ears and continue reading websites that also know nothing about it.

If someone's plugging their ears, it's you. The hydrogen stuff you see in Japan is about burining the very polluting shale in order to make hydrogen via electricity of it. They think they have something like a new coming of the oil industry in there, but it's really a misguided and stupid idea since hydrogen doesn't store well and therefore transport of it is downright idiotic. Meanwhile, they have loss leader cars at limited quantities for places like California only, where they're highly irrelevent anyway. Batteries can store a charge for up to years and are an order of magnitude more efficient, whereas you'd have to find a shitload of new powerplants for the lossy and moronic way hydrogen economy works.

Not only are you ignorant about H2, apparently you don't know much about batteries either. Try leaving your Tesla at an airport for 3 weeks and then report back on the range available.

whereas you'd have to find a shitload of new powerplants for the lossy and moronic way hydrogen economy works.

Waste of time. Good luck with your batteries - and no you aren't going to bury dead ones in my backyard. Tesla's are throwaway cars because who is going to spend $12-15k on a replacement battery when the existing one has a range of ~80 miles?
