Signicant storage is cheap and getting cheaper, much faster than wind or solar ever did. By the time we have built out enough renewables to benefit from storage, storage will be cheap enough to hardly notice.
- dsomers 5y agoHi, I’m curious, can you tell me about the most promising storage technology being rolled out now?

- ncmncm 5y agoCanada has plenty of mountains to support conventional pumped hydro. There are a lot of interesting variations on pumped hydro that do not depend so much on geography. Undersea variations are most interesting. Wikipedia explains some of them. Undersea compressed air is also interesting: a bag anchored to the sea bed is inflated with air. Advantage is it needs no mechanical or electrical apparatus underwater. Similarly, a float attached to a pulley anchored to the seabed, attached to an electric winch onshore, or on the side of a wind turbine post. There are the usual rapidly improving battery chemistries, prominently iron-air batteries, with utility-scale factories already under construction, to deliver in 2023, with plenty of time to spare.
