Even if it was fully green, you can’t run an electrolysis system from home. So you have to buy it, so there’s a market and an expensive solution.

Electricity comes out the wall.

Which unless you have solar, you are paying for. Even if you have solar, you are paying off the panels, batteries and inverter/chargers over a period of time.

Nothing is free.

What do you mean?

You can run electrolysis from a cup.

I know, I have one of those weird H shaped flasks with the plat electrodes.

I also have a gas bbq, yet couldn't fill up a LNG car at my house. Maybe there's something more to it than just making small amounts of room temperature / pressure H2.

You can’t make and store bulk hydrogen at home
