Pushing water uphill is relatively cheap and ~80% efficient. We can build more 2x nuclear power station equivalent "batteries" like fengning fairly easily.
- laurencerowe 5y agoAre there many sites with appropriate geology to build any substantial number of pumped storage stations?
- pydry 5y agoCant find it now but there was a study i remember seeing that suggested that there were 100x as many as needed.
