For the balance between energy supply and demand to stay as stable as possible, the energy loss during the whole process (energy supply / storage / output) has to be minimal. Due to the simple architecture of the structure, energy losses are expected to be very small. Apart from hydraulic losses in the pumps and turbines, only minimal losses are expected at the inlet and the outlet. A major advantage lies in the constant pressure head: it allows the pumps and turbines to operate highly efficiently at any given time.

As a result, the overall efficiency of the new Buoyant Energy concept will exceed the efficiency of conventional pumped storage plants (75% to 80%).
