Spain shows the way on green hydrogen

Learn what 'fact' means. It does not mean 'Universal Truth'.

According to the US Department of Energy -
1 kg of hydrogen has the same energy content as
1 gallon (3.2 kg) of gasoline.

lower heating value
hydrogen - 52,217 btu/lb
Diesel fuel - 18,394 btu/lb

Look at the energy per gallon, dumbass.

Each time you convert from one form of energy to another, there is a loss of available energy, as some is always lost to waste heat during conversion. Further, to use wind to generate hydrogen to cover those times when the wind isn't blowing means that power is NOT available for anything else when the wind is blowing. In other words, you must add MORE wind generators just to power the ballasting system (hydrogen generation in this case).

Wind generation is most suitable in sparsely populated areas. Sparsely populated areas have few transmission lines. Areas or Texas have wind generators going unused because other wind generators are filling the capacity of the transmission lines. Those generators could be making hydrogen that could be used to generate electricity or run cars. Wind generation MUST have thermal generation to back it up. That thermal generation could be fueled by clean hydrogen. That would make water instead of carbon dioxide.

Other than specialized applications, wind generators are impractical. They are expensive and produce very little power compared to a regular power plant. A single nuclear power plant can produce more power than ALL the wind generators in a State combined.

You obviously haven't driven through sparsely populated areas, like I do. There are transmission lines and distribution lines pretty much everywhere.

No. They are piddle power. They do not fill the capacity of any transmission line.
They are going unused because they are expensive. Cheaper forms of power are available.

The electricity isn't needed. That's why they aren't running. Other reasons is that the wind available is not suitable, or the machine is iced, or is undergoing maintenance, or many other reasons. You are describing a ballasting system. It's not enough to run a fleet of cars.

So you are describing what is known as a ballasting system. These systems store energy in some form (hydrogen, batteries, pumping water up to a higher level, etc), which is then used to augment power when demand is high and the generator is insufficient. Remember that a ballast costs additional money to build and maintain.

Burning any hydrocarbon produces water as it's primary exhaust. CO2 is also produced, but so what? What is wrong with CO2?

No gas or vapor is capable of warming the Earth.
