Gottlieb Paludan Architects has developed vision projects for ‘energy islands’ in Denmark, India, Florida and China in collaboration with Risø DTU, an institute of the Technical University of Denmark.

As the production of renewable energy rarely match the immediate requirement, renewable energy cannot as yet replace conventional power stations, only supplement their production. The Green Power Island project provides a method of storing the renewable energy whenever production outweighs demand. The project is a vision for energy storage on a huge scale with the aid of seawater.

The artificial energy islands will have deep reservoirs and the power will be generated either by erecting wind turbines or by floating pontoons with solar panels. At times of low demand, water will be pumped out of the reservoir and when demand rises, sea water will be let back in to the reservoir via turbines, regenerating 75 per cent of the electricity.

As the reservoir will never be drained completely, it can be used for aquaculture, either for foodstuffs, such as mussels or algae or for the cultivation of algae for biomass production. Depending on location and size, the energy islands may also be developed and provide space for homes, airports or harbours, agriculture or recreational facilities.
