In Search for Cheaper, Longer Energy Storage, Mountain Gravity Could Eventually Top Lithium-Ion
Mountain gravity energy storage could be a viable way to store electricity for longer durations and at larger scales than lithium-ion battery storage can, according to a study recently published in the academic journal Energy. The idea of gravity as a form of storage is an example of ongoing research into additional storage options beyond lithium-ion batteries. Despite large cost reductions over the past several years, some experts still view lithium-ion systems as not economically-efficient enough at scale to fully back up the amount of renewable energy expected to come onto the grid due to states’ long-term clean energy goals.
