Because prototype vehicles are not supposed to be profit centers. The fact that now you are shifting to cars shows how uninterested you were in this topic to begin with.

Please stop making shit up. We already have seen people reuse or at least test natural gas infrastructure with hydrogen. There are no showstopper problems. It is a fully solvable problem and is going to happen.

You literally are making up your own fictional scenario to rationalize how you can disconnect $0.02/kWh electricity from cheap hydrogen. This is pure incoherent rubbish.

Ultimately, you are creating an alternative reality to rationalize your delusion that batteries can power anything while nothing else can. No fucking idea why are you ranting about nuclear safety either. It is one of the safest energy sources out there.

Hydrogen systems still being classified as prototypes after decades of research should tell you something. Nobody is making hydrogen boats because they’re simply inferior in just about every conceivable way. Cars got heavily subsidized, billions in R&D over decades, and are a failure. Hydrogen boats aren’t even vaguely worth trying to bring to market.

Economics uncovers bullshit, you can’t hand wave away the cost of infrastructure, someone needs to pay to create and maintain it. Solar can hit 2c/kWh for a few hours per day in a few areas of the globe, but now you’re both idling infrastructure and stuck with long distance transportation of Hydrogen and or electricity which has their own associated costs. Just do X sounds great, but doing X always has associated costs.

For comparison, including transportation and all other overhead bunker fuel gives you ~15c/kWh after you burn it, though this varies a lot. It’s horrifyingly polluting, but dirt cheap.

Scale alone isn’t going to fix green hydrogen it requires a fundamental breakthrough.

And BEVs are well over a hundred years old. You are so fucking dishonest, it's seriously painful talking to you. You didn't even register the part where I said hydrogen boats already exist. You aren't even trying to have a conversation about green shipping. It's all just about more BEV marketing from you. Everything you say can be a lie to further this goal.

Seriously, who do you work for? I can't imagine you not having an agenda here.

Cars are meaningful because they clearly demonstrate current Hydrogen pricing and technical issues.

Economics isn’t rubbish. Yes you can get X kWh at below Yc/kWh every month, *as long as you are willing to let equipment sit mostly idle. My point about 3c/kWh is simply the point where you can both operate equipment 1/3 of the time in most locations thus minimizing transmission issues, and you aren’t limited by the surplus of the local electricity grid. It’s simply a point of comparison. Sure, you can get

It’s also meaningful when including transportation and all other overhead bunker fuel gives you ~15c/kWh after you burn it, though this varies a lot. https://agtransport.usda.gov/Fuel/Daily-Bunker-Fuel-Prices/y...

Include overhead and green hydrogen generation is currently dramatically more expensive and it needs drastic efficiency gains to be viable. That’s simply the truth.

Your only input is your super cheap electricity and water. Your own logic dictates that hydrogen must be cheap. Scaling up is the only thing that has to happen.

You should stop doing logical backflips and making nonsensical comparisons.
