Hydrogen is not created by electrolysis powered by fossil fuels. Most is created by SMR directly from methane.
But since you insist:
charging a battery is about 90% efficient. You put 10 kWh in, you get 9kWh in. Discharching is more than 90% efficient, let’s say 80% source to motor. Pulling 10 kWh from the socket gives the motor 8kWh to work with.
electrysis of water has a typical efficiency of 70%, in lab conditions 80%. Then you need to compress it, creating heat and losing another 10%. Finally, fuel cells are about 50% efficient, leaving you around 30% of the original energy. So pulling 10kWh from the socket leaves you with 3kWh to drive with.
That’s (among others) how batteries are superior to hydrogen.
My point is you’re gaslighting to pretend that fossil fuels burnt to power EV’s are better fossil fuels burnt to power electrolysis.
They both need the energy source to be made clean, but hydrogen will be cleaner at that point, regardless of the efficiency issues (which are already being addressed).
I just wrote why fossil fuels burnt for charging EVs are better than electrolysis. Not gaslighting, just math. Almost triple better in fact. Did you read it or just plugged you ears and sang very loudly?
And again, if you have fossil fuels you don’t do electrolysis, there’s better, more efficient methods to reform methane into hydrogen. Not close to the efficiency of batteries, but better than electrolysis. Use better arguments to defend your opinion, man.
And on top of that, think about the infrastructure. Compressing, transporting and even storing hydrogen requires complex equipment. I can generate green energy at home and charge my car with it, right now. We’ll, not right know as it almost midnight, but I did it earlier today. Not at some point in the future, not addressing issues and maybe and perhaps. Literally today. No transport, other than the cables from my roof to my car.
And if I didn’t have solar panels I could buy a generator for 300 bucks and create my electricity at home with some gasoline.
This doesn’t include the one thing I explicitly asked for and is a big obstacle for at home production: compressing hydrogen to 700 atmospheres.
The you still have to overcome the 50% energy loss in the fuel cell. And even this article doesn’t mention any numbers regarding the efficiency of the electrolysis.
You don’t understand the commitment to batteries? They are 3 times more efficient, easier to fill, and easier to recover energy from. And those obstacles don’t deem to go away anytime soon.
Please explain how a battery charged from fossil fuels is superior to electrolysis powered by fossil fuels.

You can also create hydrogen at home. Which is why companies oppose it.
Please tell me you top 5 favorite hydrogen compressors. Oh, you mean putting a 9v battery in salt water to create bubbles? How fun!

I don’t understand this obsessive commitment to larger batteries, and anti-hydrogen tech. It’s not an either-or. The technologies work together.

If you would like a specific answer, you should look it up yourself to your own satisfaction, instead of sealioning.
