Push2Heat: Felix Schoeller installs the Group’s first high-temperature heat pump at its Weissenborn plant
In the framework of the EU-funded Push2Heat project, four demonstration plants are being planned in Europe in a collaboration of international partners and research institutes. At its Weissenborn site, Felix Schoeller is working with Fraunhofer IEG and heat pump supplier SPH to design and build a high-temperature heat pump that uses waste heat from paper production to generate new process steam for the drying stage. An existing 45°C waste heat circuit is used as the heat source. The heat pump generates steam at 124°C with a COP (coefficient of performance) of approximately 2.5, which can be directly reused in production.
Goals
The project aims to demonstrate the contribution that high-temperature heat pumps can make to the decarbonisation strategy of the Group. In addition to the CO2 savings achieved, economic efficiency and process safety are of great importance to us. The exchange of ideas in the international project and the support of our partners provides a comprehensive basis for achieving these goals.

SPH Sustainable Process Heat GmbH (spheat.de)
“The Push2Heat project is part of our Green Lighthouse initiative, by means of which we are developing and introducing sustainable technologies on an industrial scale at the Weissenborn site. The sustainable generation of process steam plays a key role in the successful transformation of our industry.”
CO2 emissionens saved
CO2 emissions saved through reduced natural gas consumption: approx. 1,200 tonnes of CO2 per annum
Amount invested
This project was funded by the European Union’s Horizon Europe research and innovation programme under grant agreement No. 101069689 (PUSH2HEAT).
Amount of investment in Horizon Call No. 101069689 (Push2Heat) for 4 demos and all participating institutes approx. €10 million.
