Gravity is weak, but it's cheap. It is indeed surprising, but plenty of research shows that the levelized cost of gravity storage is cheaper than Li-ion batteries - even if you assume that Li-ion will get 4x cheaper in the next 20 years. There are other problems with Li-ion as well that will prevent it from scaling up to the amount of storage that our grid will need. I discuss all this with lots of citations in a white paper here https://github.com/syllable-hq/uphs-feasibility-study https://github.com/syllable-hq/uphs-feasibility-study

- syllable_studio 6y agoNo worries. Here is a good resource that talks about the levelized costs of gravity storage. It's estimated to be much cheaper than Li-ion battery storage on large scales. https://www.storage-lab.com/gravity-based-storage https://www.storage-lab.com/gravity-based-storage
