The Bochum pilot will take place at of the former Opel plant in Bochum, called “Mark 51°7”. For the preparation and marketing of the land Bochum Perspektive 2022 GmbH was founded with the aim to locate a broad mixture of businesses and office buildings in the area.
Due to the former mining activities on this site, there is a large mine water reservoir at a depth of several hundred meters, which can be used as an energy storage.

The pilot customer Faiveley is connected to the thermal mine water network via a substation with a local heat pump. This thermal network will be expanded later, with further substations (heating and cooling centre with heat pumps) to follow. The network is set up in such a way that the heating and cooling capacities can be made available to different customers at different temperatures.
Closed energy loops
The network will be set up in such a way that it will be possible to exchange heat and cold requirements between customers in the future expansion with several substations and connected secondary subnetworks. The net flows are balanced by short-term decentralized storage of the substations and by the heat source and low-grade thermal source of the mine water reservoir. The latter also serves as long-term (seasonal) centralized large-scale storage.
Low grade thermal energy sources
The low-grade thermal source of the mine water reservoir covers a large part of the heating and cooling requirements. Short-term peaks in demand are partially offset by short-term decentralized storage.
