When supply exceeds demand, you could just "bleed it off" or reduce supply by decoupling generators.
- tlocke 5y agoI think we're talking at cross-purposes. I'm saying that it's only when the supply from renewables exceeds total demand, you need storage. Otherwise if the supply from renewables doesn't meet demand then there's nothing left over to store, and you'd need to start burning gas. Note that the end-game is that renewables become so pervasive that there are significant periods when renewable generation does exceed total demand, and then you generate hydrogen with it. That hydrogen then displaces the natural gas that's currently used, the storage / pipework infrastructure for natural gas being equally suitable for hydrogen.
