Storing electrical energy is crucial for the transformation of the electrical power system towards using renewable energy sources. A less common type of storage are Compressed Air Energy Storage (CAES) systems. There are only two power plants of this type worldwide, one of which is located in Huntorf, Lower-Saxony, Germany. The goal of the project “Huntorf2020”, a joint project of Clausthal University of Technology and power plant operator Uniper Kraftwerke GmbH, is to determine the possibilities to enhance the flexibility of the storage system by advancing the technology and analysing the demands of the local power grid. The project focuses on the use of hydrogen produced with electrolysis of water powered by renewable energies (below: “synthetic hydrogen”) instead of natural gas to avoid CO2-emissions.
