You are effective saying that green hydrogen can never be as cheap as fossil-fuel based hydrogen

No, I'm not even engaging in the boondoggle that is "green" versus all the other types of hydrogen. I'm telling you that producing hydrogen from electricity is nonsensical when you can just use the electricity.

and is basically climate doomerism.

No, it's saying this is a stupid solution not that there's no solution.

It’s all made from stuff that is available everywhere.

But Hydrogen, largely, is not freely available. It's found bonded to other atoms, and those bonds require energy to break. The problem you face is that the amount of energy necessary to break those bonds is higher than the amount of energy you can get back out of the hydrogen.

The cost floor is zero because of that.

This is pure nonsense and fantasy. You do not have a supply of freely available hydrogen, which means your cost floor is the cost of breaking hydrogen out of its existing bonds. That's like saying the cost floor to charge a battery is zero. It's nonsense. You need to put energy into producing the hydrogen, plain and simple.

The rest of your comment is just nonsense. You're attempting to put words in my mouth and inventing arguments I'm not having. So I'm not engaging with that in any way.

You are still missing the point then. You cannot use that electricity. It is going to be curtailed electricity and is basically lost in the production process.

Taking that unusable electricity making something out of it will drive the cost of hydrogen to basically zero. This is the fundamental reason why solar also became so cheap, despite PVs being "inefficient." You're simply taking something free and making something useful out of it.

Like I said from the beginning, you are just repeating the same anti-wind and anti-solar arguments of the past. You can insist that you didn't actually say that or claim that this is somehow different, but none of that is meaningful. It is just closed-minded nonsense regardless.

5%. You're talking about 5% of energy transmitted is lost. So you're going to start a hydrogen revolution with 5%?

I get it, you've found a thing you can be a champion for. But you're blinded to the real world by your overzealous fandom.

Because electricity is traditionally sent very short distances. It's too bad that this is going away. Your renewable energy resource may be thousands of miles away in the future.

PS: It was a pipeline that sent natural gas to your local gas turbine power plant. If electricity losses was always going to be 5%, why did that pipeline exist at all?

P.S.: My power plant doesn't burn hydrogen.

I literally said natural gas...
