Industrial heat recovery for district heating

In a district heating project, heat is generated at a central location and distributed to homes, businesses and industry in a local area.
In this particular case:
TOTAL Energies has committed to the goal of reducing CO2 emissions from its plant in Leuna by 2027. The company plans to supply Leipzig’s district heating network with 670 GWh/year of waste heat from several process units. The city of Leipzig is also keen to decarbonise its heating network.
Therefore, a new heat pipeline approximately 20 km long will be built to enable this project. The aim is to use waste heat from existing process units by installing a series of new heat exchangers at 20 different locations. In addition, a new 15.5 km hot water network with a diameter of 3 to 24 inches will be built at the Leuna site.
