That's a beautiful photo. I really need to make my way up there

Aktually you're wrong

I guess I'll have to get my hair done elsewhere

It is possible today. They are being built to make it possible and there are small scale sites that prove it's possible. I'm not talking about R&D development.

Yes, use excess renewable energy while the sun is shining and the wind is blowing to generate green hydrogen. Pump it into some salt caverns (or storage tanks if less MWh are needed). Then when the renewable resource isn't producing, you have hydrogen ready to go for longer durations.

It's not suitable for every application, but there are scenarios where hydrogen makes sense.

Hydrogen isn't fighting for the same space as lithium batteries. Hydrogen would work a lot better for long duration or seasonal storage which lithium batteries just can't do economically. And we don't have the need for that long duration storage in the US yet (except maybe in California) and won't until there's around 75% renewable penetration, so it's fine if hydrogen is 5 years out.

Or we don't rely on just one technology and invest in multiple ones since each technology may be best suited for certain applications.

Why are you saying it's not possible? There are a lot of projects being developed right now with large solar sites paired with electrolysers to produce green hydrogen.
