Uniper, Evonik, and Iqony Launch Innovative Heat Pump in Germany
Uniper and Evonik have commissioned a high-temperature heat pump in Herne, Germany, to convert industrial waste heat into district heating for 1,000 homes. This project is anticipated to reduce annual CO₂ emissions by up to 1,750 tons, emphasizing the importance of industrial collaboration in energy system transformation.

In Herne, Germany, Uniper and Evonik have commissioned a high-temperature heat pump capable of converting industrial waste heat into district heating, supporting around 1,000 households. The system can deliver up to 1.5 megawatts of thermal energy and aims to reduce carbon emissions by as much as 1,750 tons annually by replacing fossil fuel heating.
This innovative approach captures low-temperature waste heat from chemical production, upgrading it for use in existing district heating networks. The initiative is designed as a pilot with significant scaling potential, with future opportunities to integrate an additional 20 megawatts of waste heat. The project illustrates the role of advanced technologies and partnerships in decarbonization and energy efficiency.
