Evonik and Uniper Launch Sustainable District Heating Project
Evonik and Uniper officially launched the Technical Options for Thermal Energy Recovery (TORTE) project in Gelsenkirchen. As one of the first phases of Evonik’s ‘Herne Green Deal’ to sustainably transform the Herne chemical site, the TORTE project will feed industrial waste heat from isophorone production into the district heating network. Around 1,000 homes in the Ruhr region will be supplied by the end of 2024.
To recover this industrial low-temperature waste heat, Uniper has installed a large on site heat pump to feed up to 1.5 megawatt of heat into the district heating network to supply local customers. This sustainably recovered heat from the Herne site will help Uniper to reduce its emissions by 1,750 tons of CO2 per year. The project also supports Evonik’s sustainability ambitions to reduce carbon emissions and its use of fossil resources at its sites.
