Are you asking a question?

Because the hydrogen I'm mentioning is accessible to be put into fuel cells.

While hydrogen is common, free H2 molecules are not

Correct. That is where fuel processing comes into play.

For all fuels, let's say gasoline for example, you can't just grab a bowl of oil from a crude oil well and dump it into your fuel tank.

The fuel needs to be carefully refined and processed.

Same with hydrogen, same with biofuels, that's how refined fuels work.

There's no skipping thermodynamics, maybe there will be a technology for an arbitrary molecule to hydrogen gas reformation but it doesn't exist to my knowledge. Electrolysis of water means breaking the bonds and that takes a lot of electrical energy.

What you're saying is correct afaik, although i don't see its bearing on hydrogen fuel generation or how it's bad for BEVs as an industry.

Are you trying to ask a question about hydrogen fuel generation or processing, or BEVs?

Or are you just lamenting that one specific fuel processing method you're aware of for FCEVs isn't as efficient as you want it to be?

[–] [email protected] 2 points 8 months ago (1 children)

The fossil fuel industry is arguing for hydrogen because to keep costs down it will be made by natural gas reforming. Otherwise cost wise, putting 1 kWh of hydrogen into cars will be maybe 40% efficiency, then using fuel cells. So just multiply whatever your cost per electric kWh by 2,5. Hydrogen usable for stationary things like steel production though. Maybe methanol fuel cells are more viable idk

Albeit this is just off the top of my head so it's not necessarily 100% correct. It is much more efficient to put electricity into batteries.

Oh for sure. I only brought up hydrogen because so many people didn't know that hydrogen is so abundant and easily processed in so many forms while I was advocating for bevs.

I got a lot of hydrogen questions while talking about bevs, I don't know why.
