I don’t think that’s right, since during times of high solar or wind production, more energy is produced than is consumed. This energy will then be used to create hydrogen. This is a very battery like concept which enables the buffering of renewable energy using hydrogen production. Because of this assymmetry we do not need twice the amount of renewable power plants.
Okay I think I understand, you mean because of the energy lost to the process during hydrogen production, right?
This is true, but it’s again a question of how can we produce climate neutral energy without employing fossil fuels or nuclear energy, and if that means we have built more renewable power plants, to fill the hydrogen tanks, why not just build them?
Sure, if it was free to build, it would be better than not having them (though worse than more efficient types of storage), assuming the cost of refining the steel breaks even.
There’s a reason fossil fuel companies fund hydrogen.

I don’t think it’s a question of efficiency. It’s a question of producing the least amount of CO2 as possible. This is where green hydrogen shines.

Of course this is more expensive. This is the price for being independent of fossil and nuclear fuel.
Fossil fuel companies support hydrogen plants that use fossil fuel to produce “grey” hydrogen, not green hydrogen produced by renewables.
