Pumped/Turbine Hydro Electric Storage System
Combining Dutch water management expertise with renewable energy in a whole new concept
Delta21 has been developed as a solution for Water Safety, Energy Storage & Nature Restoration and Recovery. This solution is currently being developed for the Rotterdam area in the Netherlands, and can be further replicated with the necessary design adjustments worldwide in areas with estuaries and flood risk areas.
Delta21 is a high water defence and an energy storage system built comprising a row of dunes and a lake of approximately 20 km2, with a pumping station and a lockable barrier. The dunes together with the lockable barrier are designed to provide sufficient protection against high seawater levels till the end of this century. The pumping station will have ample capacity to pump excess discharges of riverwater into the sea. Under normal climate conditions the lake can be used as a Pumped Hydro Storage facility with a capacity of 1,8 GWe.
