There is no question that the energy transition is long overdue. We show that its realisation is easy with our innovative TESCORE storage system, which makes an immediate reduction of CO2 emissions possible. At LUMENION, we rather speak of a heat transition regarding the current energy demand: More than 50 percent of final energy consumption in Germany is for heat; in the industrial sector it is even around two-thirds, most of which is used for process heat. With our high-temperature storage system, we make renewable energies usable for the heating market and thus make a significant contribution to the heat transition.

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 energy generation plants, can compensate for grid bottlenecks and enables the decarbonisation of heat-led processes.

TESCORE can be charged in about four to six hours (continuously or discontinuously over the course of a day) – for example, when electricity prices drop during off-peak periods. With the help of an electrically powered heater, the storage core is then heated up to 600 degrees. Whenever energy is needed, the discharge process can be started, in which the stored thermal energy is transferred to a heat exchanger. The possibility to simultaneously charge and discharge the system ensures maximum availability and optimises the use of resources.

Possible applications include the supply of process heat in the industrial sector. Wherever high-temperature steam is needed for industrial processes, for example in the chemical or food industry, the storage system can be used as a quick solution for a climate-neutral energy supply. Integration into local and district heating networks is also possible, as already demonstrated by our pilot project in Berlin-Tegel: since 2020, a thermal storage unit with a capacity of 2.4 MWh has been supplying around 360 surrounding flats with hot water.

Depending on the energy demand, TESCORE is scalable in size; storage capacities between 0.2 MWh and 500 MWh are possible. Storage modules can be flexibly combined so that we have the right storage solution for every individual need.

We use steel as material for our storage core because it offers many advantages: Thanks to its robustness and high density, a lot of energy can be stored in little space. Thanks to the durability of steel, the operating life of our storage system is at least 20 years – and afterwards, steel can even be recycled with a residual value of 40 %. All other components of the system are also industry-proven and can be sourced locally, which promotes regional value creation. TESCORE can thus be operated and maintained without risk or permits.
