Thermal energy storage systems for 100% renewable energy supply

Page last modified
August 4 2023

With its innovative thermal energy storage systems, LUMENION makes a stable heat supply from renewable sources possible: by separating energy supply and demand, fluctuating wind power can be used effectively.

The basic idea of our power-to-heat technology is to shift the energy behind generation peaks out of the power grid and into the heating grid, thus serving as a relief valve for the power grid. This ensures system security, maximises the use of power plants, compensates for grid congestion and enables the decarbonisation of heat-powered processes.

TESCORE, our thermal energy storage system, can be charged in about four to six hours – for example, when electricity prices drop during off-peak periods. The storage core is then heated up to 600 degrees. Whenever energy is needed, the stored thermal energy is transferred to a heat exchanger. Depending on the energy demand, TESCORE is scalable in size between 0.2 MWh and 500 MWh.

LUMENION is a cleantech start-up from Berlin and an active contributor to the energy transition. We use an innovative technology to store green electricity as high-temperature heat in steel storage modules (TES). In this way, we make renewable energies available at any time of day or year and solve a central problem of decarbonisation: fluctuations and temporal interruptions of wind and solar power.
