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.
You do though. You need to refill the storage faster than it is drained, it's a simple numbers game.
If you waste half the electricity produced going hydrogen over pumped hydro then you need more renewables.

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.
