Well, for storing it for the night, I typically hear that battery or saline storage is much more efficient (something like 60% efficiency for the whole cycle of storing and retrieving).
So, unless it’s much more expensive to build this battery/saline storage, it seems like it’d only be economical to blow it on hydrogen, if you’ve got your storage filled up for the night + somewhat of a buffer.
I guess, this theory might be void, if companies are willing to pay a lot of money for hydrogen. Some industries do strictly need hydrogen for chemical processes, so I guess, those would pay…
I think you’re right, hydrogen is ludicrous, and bang for buck, some other tech will win out for time shifting the power, probably pumped hydro.
edit to add: Hydrogen is ludicrous in the primary context of a battery.
There’s other potential uses such as making steel, making ammonia/fertilizer etc that could change the equation again. Hell, you might even find it desirable to make it HERE and transport it THERE as a battery, but again, the maths are currently wrong.
