- Manuel_D 4y agoCost today? Or last year? Lithium prices have increased over 400% last year. If demand increases suddenly, price will increase as well. The demand for batteries has led to drastic increases in the cost of input materials: https://www.canarymedia.com/articles/batteries/chart-lithium-prices-are-through-the-roof-this-year https://www.canarymedia.com/articles/batteries/chart-lithium... For this reason, the costs of recent battery storage has risen considerably. Recent storage projects ended up paying $567/Kwh : https://www.utilitydive.com/news/new-york-battery-storage-costs-rise-interconnection-queue-12-gw/621954/ https://www.utilitydive.com/news/new-york-battery-storage-co... This is the scaling problem: if you try to deploy batteries at scales relevant to the energy grid you outstrip the supply of inputs. In order to keep up with demand, extraction industries have to tap more and more inaccessible reserves thus driving up costs. Remember, global electricity usage is 60 TWh per day. And that's just electricity, total energy use is about twice that at 120 TWh per day. Even just 12 hours of storage is hundreds of times the annual battery output - most of which isn't going to grid storage but rather electric vehicles.
