What is the algorithm for gravity energy storage
“In each gravity-based energy storage, a certain mass is moved from a lower point to an upper point – with the use of a pump, if water for example – which represents ‘charging’ the storage, and from a higher to a lower point which creates a discharge of energy,” says Energy Vault CEO and co-founder Robert Piconi.[Free PDF Download]
