The Fraunhofer Energy Alliance develops new technologies for the usage of hydropower, both small and large scale. For example, researchers at Fraunhofer have developed an innovative power generator that uses wastewater to economically generate electrical energy even with small amounts of water and low pressure differences.
Experts at Fraunhofer see great potentials in the research field of marine energy. For this purpose, innovative technologies and regulatory approaches for marine current turbines are being developed. Furthermore, subsea pumped-storage power plants offer a completely new storage method. They use the sea as the upper reservoir and a hollow body on the seabed as the lower reservoir.
