Reading through the linked article, I don't think that's the way it's designed to be used. It can completely empty itself in 8 hours. That sounds like it's specifically designed to augment renewables at night and charge during the day, cycling every 24 hours.
- XorNot 3y agoThat's absolutely how it's going to be used because it's cost efficient for the owner. But if you're electrical grid doesn't mostly have always on sources to backstop it, if you were all renewables and storage, then how much storage would you need to guarantee supply - 24/7/365 days a year.
- pfdietz 3y agoSo, you're saying it would be stupid to use 8 hours capacity pumped hydro for long term storage. Thanks for the observation, Mr. Obvious. You also seem to be implying longer term storage of some form isn't feasible. If so, you are incorrect. Note that I pointed to this project to debunk the falsehood that the locations for PHES are scarce, not to claim that PHES is good for long term storage.
