Caverion and Stadtwerke Bochum expand their collaboration effort
In the heart of Bochum-Laer, the Mark 51°7 industrial park is set to revolutionise its energy supply. Bochum's municipal utilities are tapping into a unique resource - mine water from a decommissioned coal mine - to provide sustainable heat and cooling for the park.
This innovative approach involves the use of mine water from depths of approximately 340 metres and 800 metres, with temperatures of 17 degrees Celsius and 28 degrees Celsius respectively. For cooling, the 17-degree water is used, while for heating, the warmer 28-degree water is utilised in the district heating network.
Heat pumps play a crucial role in this process, bringing the mine water to the temperature level required for heating and cooling. In addition to previously commissioned process and energy engineering services, the collaboration now includes ventilation, sanitation, electrical engineering, and building automation.
Caverion Germany is at the forefront of this project, optimising the potential of the equipment with their expertise in building automation. They are responsible for installing the equipment on-site and supporting customers with complementary engineering services in the concept phase for heat and cooling generation.
Compression chillers are also employed to cover peak loads for cooling. A combined heat and power plant provides the electrical energy for the technical facilities.
The joint goal is to start supplying the connected commercially used buildings with heat and cooling in spring 2026. The search results do not provide information about the company involved in planning and implementing the combined heating and cooling plant, nor about the planned start of heating and cooling supply in spring 2026.
Expanding their collaboration, Caverion and Bochum's municipal utilities are now working together on the Eastern Energy Hub in the Mark 51°7 industrial park. The innovation in this project lies in the use of mine water for sustainable heat and cooling supply, marking a significant step towards a greener future for Bochum.
