And what do you know? They're both pressure vessels. Why would one cost significantly more than the other? With modern technology, the cost of making hydrogen tanks should be fairly cheap.
What do I know? I've designed pressure vessels as a job.
No. The material requirements for a H2 pressure vessel is vastly more expensive for the reasons I stated above.
H2 reacts with everything, Extreme low carbon stainless is required, on top of the tank wouldn't last long due to hydrogen embrittlement.
Hydrogen being the smallest element literally just permeates through every material.
My current profession involves large equipment. Especially electrically driven equipment.
The mining industry would pay BILLIONS.. scratch that.. TRILLIONS of dollars if hydrogen source was achievable, if they could reduce the need to vent their mines, if their equipment could output only water...
They already pay $$$$$$ for fully electric mining equipment. I've personally worked on those machines and many others like fully electric passenger buses.
They've all abandoned H2. Batteries are the future. H2 is not.
Unless someone can use H2 in a kind of fusion process to generate power... H2 will never be a thing. In combustion or Fuel cell form.
Again, if I was a good idea, we'd be doing it already. No new technology in either materials, chemistry or combustion have come to light that could possibly make H2 viable.
It's a green-washing farce until someone can crack open the hydrogen atom.
Either you're the dumbest engineer in the field or you just made all that up. Seriously, your post is just a load of bull.
We already have an entire system for these types of tanks. They go from Type I to Type V: https://www.compositesworld.com/articles/composites-end-markets-pressure-vessels-2023
Much of the focus with hydrogen vehicles is using Type III or Type IV which have inner linings and don't have the problems with leakage or embrittlement. Eventually, the goal is the switch to all-composite Type V which don't need inner linings. And FYI, this is the same system used for CNG. So costs are in fact, very similar to each other.
Funny because that's exactly what is happening. Billions are being spent right now:

https://rollcall.com/2023/04/20/hydrogen-energy-gets-ready-for-its-close-up-as-us-funds-flow/
Eventually, this will likely reach into the trillions of dollars: https://www.deloitte.com/global/en/about/press-room/new-deloitte-report-emerging-green-hydrogen-market.html
The rest of your post is either just pure Ludditism or ridiculous pro-battery fanboyism. It's objectively false. In fact, you're quite literally implying that the original story we're talking about is a work of fiction. You should be embarrassed to have written such nonsense.
Well you keep believing your arm-chair internet articles, while we are in the real world doing actual implementation of technologies.
Check in another 5 years and you can tell all of us how it's still 'almost' here along side fusion.
Because billions in investments are just in our collective imagination…
You’re just repeating the same bullshit people said about wind and solar. You are an embarrassment. Everyone will laugh at you in five years.
