  Well okay, but if we're bringing those things into it, hydrogen requires cryogenic storage and is, ah, famously flammable, even when it's not pressurized to 350 bar. I wasn't saying Li-ion is perfect - all I was trying to say was that if you want to compare like with like, you can't compare batteries with just hydrogen - the hydrogen is just the fuel, while the battery is both the fuel and the generator.

    You need to do some more research. Hydrogen is 57 times lighter than air, which means in the case of a leak, it disperses almost instantaneously...almost always completely dissipating before having the chance to ignite at all. Rapid depressurization will freeze nearly everything in it's path, minimizing your chances of a heat induced ignition. And unless you're giving it liquid oxygen, you have almost no chance of an explosion. https://hydrogen.wsu.edu/2017/03/17/so-just-how-dangerous-is-hydrogen-fuel/ https://hydrogen.wsu.edu/2017/03/17/so-just-how-dangerous-is...

    > hydrogen requires cryogenic storage Not for grid-scale stationary storage, it doesn't. You store it underground as compressed gas, just as many millions of tonnes of natural gas are stored today.

  Gas cars are 11x more likely to catch fire than an EV.
