"with its “in-a-box” undersea system, you don’t have to find a spot to build a new pumped hydro reservoir on land... makes it possible to mix and merge storage volume and capacity. The storage volume can be sized by connecting the exact amount of rigid reservoir elements, each with a storage volume of 10 MWh... you pump seawater from the rigid reservoir into the bladder. Pressure within the bladder does the rest. When extra kilowatts are needed, water is released to run turbines"
