Pumped storage requires very specific geography and how much energy can be stored is very dependant on height differences. It is also only 70-80% efficient. Compressed-air energy storage also requires specific geography. Molten salt is not going to be a great idea in places that have lots of wind, but not a lot of sun (UK in winter for example).
To replace strip mined coal burning generators and fracked gas we need a mix of just about everything.
- dharma1 7y agoI agree it's going to be a combination of solutions with energy storage, depending on what you need. Batteries are good for short-term, portable storage. The other solutions you mentioned may be better for long-term, non-portable storage. I also think we can get more mileage out of chemical fuels produced with renewables - ammonia, hydrogen. https://www.greentechmedia.com/articles/read/siemens-ammonia-hydrogen-energy-storage https://www.greentechmedia.com/articles/read/siemens-ammonia... https://www.sciencemag.org/news/2019/03/new-fuel-cell-could-help-fix-renewable-energy-storage-problem https://www.sciencemag.org/news/2019/03/new-fuel-cell-could-...
- sunstone 7y agoIt may be that federated electric vehicle batteries become all the storage we need as long as power grids are integrated more broadly.
