Using an excisting power plant to store heat. Source: DLR.
Thermal storage power plants are thermal power plants equipped with a large thermal energy storage that can be heated electrically. They can be charged by electricity from renewable sources and thus provide renewable energy "base load capable". Ideally, thermal storage power plants are used in combination with heat sinks, so that the heat released by the cycle can also be used and a high degree of utilization of the overall process is possible. Both existing power plants (e.g. fired with coal, gas, biomass) can be converted (so-called REPURPOSING) and new plants can be built in connection with the expansion of renewable energies. The users of the technology are large power plant operators, municipal utilities as well as industrial processes with electricity and heat demand in Germany, Europe and worldwide.
The goal is to advance the development and implementation of concepts to cover the residual load with CO2 neutral energy through the use of thermal storage technologies in an international context and the implementation of thermal storage in the context of VAC. The tasks involved are:
