So what I'm hearing is, if I build my own electrolysis station driven by a solar panel array, there's quickly going to be a glut of extremely cheap hydrogen cars coming out of So.Cal....
That's the fun thing - after you make the hydrogen you have to compress it to 10,000 PSI and cool it to -40 to actually get it into the car. And make sure the pumps, pipes and cooling gear are all made of materials that won't be destroyed by exposure to high pressure hydrogen.
It'd probably be a lot cheaper and easier to gut the car and replace the fuel cell and tanks with batteries and a charger.
I've never done any of my projects because they were cheap or good. I understand how to do proper engineering considering I have a couple years of experience, and understand what I don't know and the fact that it's dangerous.
fuck it, we ball
Breaking news: Explosion at local home, suspected meth lab.
That's the spirit!
I'm not saying building your own home filling station is impossible, just that it's probably really expensive and a terrible idea.
You have to build something they can handle 600 bar / 10.000 PSI. You don't want to be standing close for your first test.
I mean, how many people bought them even there? Isnt there like, one model that anyone has even tried to sell to the public, just from toyota stubbornly insisting that EVs wont work despite all the working EVs that already exist?
I live in the Bay Area and I’ve seen a surprising number of them. But then again I think their R&D office is in a nearby city so maybe it’s just a bunch of employees driving them.
Enough that there will still be some available. If hydrogen becomes unavailable then the car's values drop to almost zero regardless of how many there are.
edit: California Energy Comission reports that there were a hair under 12,000 hydrogen fuel-cell vehicles operating in California in 2023
I think that Toyota recently announced they sold a total of 14,000 (in the US, I’m assuming). They also announced that they were planning on continuing production on the same article, but I don’t know what this will do to their plans.
First of all, there are three (popular) hydrogen cars available, and only one of them is from Toyota. And more are scheduled to launch very soon.
Everyone who's tested those three cars loves them. The Toyota Mirai is supposedly very similar to, and in fact nicer than, the Lexus LS 500 and it's also tens of thousands of dollars cheaper than that car. When (and I believe it is a "when") hydrogen is easier to access, it's going to take off.
The only real drawback Hydrogen ever had was cost. But that's not an issue anymore, prices have come down a lot. And the "range anxiety" issue is helped tremendously by just having a really really long range. You're only going to fill up twice a month or so.
Hydrogen's fundamental problem is that it isn't competing with fossil fuels any more, it's competing with battery EVs. And the inefficiency means even if all the filling station hardware was free, driving on hydrogen can never be less than three times the cost of driving on electricity.
