Industrial Waste Heat

Storage of industrial Waste Heat

Industrial waste heat at a high temperature-level is valuable energy that can be used before it is released into the atmosphere or cooled down expensively. No additional fossil fuels are required to use the HTTES.

Industrial waste heat can be stored at a high temperature-level and either be fed back into the process or used for power generation in an ORC at a later stage.

Waste Heat Extraction from Industrial Processes

The high-temperature heat storage is particularly well suited to discontinuous, energy-intensive industrial processes, where energy efficiency can be significantly improved and the system can pay for itself within 1-3 years.

Waste heat is extracted via a heat exchanger or directly from the process at a temperature-level of 250 to 1030 °C and stored in the HTTES.


The modular system allows for storage capacities in the range of MWh to GWh with very high thermal power, so that the storage can be fully charged and discharged within a few hours.


The thermal energy is fed back to the process during discharging. If there is no heat demand, e.g. an ORC for power generation can be operated.
