Green Power Island – A Blue Battery for Green Energy
One of the great challenges in the transition to an energy system based on renewables is to align the fluctuating energy production to match the patterns of consumption. Fluctuating energy sources such as wind and solar cannot be calibrated to match variations in energy consumption, and as a result these sources are bound to produce power at times of low demand – and to not produce at times of peak demand.
Large-scale energy storage of excess solar and wind power could provide the balancing power necessary to create a renewables-based energy system that does not compromise efficiency, stability or security of power supply.
Artificial energy islands balanced by seawater'
Green Power Island is a visionary concept for constructing artificial energy islands for large-scale storage by means of seawater. It draws inspiration from mountainous countries such as Spain and Norway, which already pump large volumes of water into high altitude reservoirs, and then lead the water back down through turbines to generate electricity in times of peak demand. This relatively simple technique is called pumped hydro.
