TMS - Thermo-Mechanical Electricity Storage System

  The scope of the project is the development, construction, experimental investigation, modeling and further development of an innovative prototype thermo-mechanical electricity storage system (CARNOT-Battery) for sector coupling of electricity and heat. The project contributes to the creation of scientific and technical prerequisites for the timely provision of an applicable and environmentally friendly electricity storage system for the sector coupling of electricity and heat. The thermo-mechanical electricity storage system works with water as working and storage medium, which is CO2-neutral, available, non-toxic and economical. The system is characterized by high charging and discharging capacity, high flexibility (fast response times), simple design without complex heat exchangers, very high cycle stability, long lifetime up to 40 years, high overall efficiency and high energy storage density. In terms of security of supply, such an electricity storage system represents a significant system component in the short-, medium- and long-term energy infrastructure and thus contributes to strengthening Germany as an industrial location.
