Název v původním jazyce

Energiespeicherung in Salzkavernen mit superkritischem CO2

Popis výsledku v původním jazyce

In addition to backup gas turbine power plants, energy storage systems are essential for a supply-secure power grid in the further expansion of the renewable energies wind and sun in Germany, in order to integrate the increasing fluctuating power generation with their low guaranteed power into the energy system. The article presents a novel storage technology, an innovative, emission-free cavern storage power plant with supercritical CO2 as pressure storage medium in a closed cycle. A sCO2 energy storage mine is comparable to a pumped storage power plant with the difference that supercritical CO2 is used instead of water and the storage does not take place at the surface in an upper and lower reservoir, but in a high- and low-pressure cavern underground in rock salt. In contrast to pumped storage power plants, the potential for storage in salt caverns is far from exhausted in Germany. Especially in Northern Germany, suitable salt domes are located in the immediate vicinity of the regions where most of the wind power is also generated on- and offshore, making large-scale energy storage with a small footprint possible. Supercritical CO2 turbines represent a technical innovation in energy conversion, the development of which is being researched worldwide for various applications. For the long-term goal of achieving climate neutrality, CO2 sinks are required for the remaining CO2 sources from industry and other sectors. The construction of sCO2 energy storage mines through Carbon Capture, Utilization and Storage (CCUS) can contribute to this.
