Scaling up sustainable solutions towards industrial decarbonization

One of the posters presented at the HTHP Sympoisum 2024 focused on the Push2Heat project which is pioneering the integration and scaling up of high-temperature heat pumps into industrial processes to demonstrate their immense potential for heat upgrade and decarbonization.

The poster was presented by Reuven Paitazoglou from Fraunhofer IEG who provided interesting insights into the work of the project. By effectively utilizing waste heat potentials and integrating full-scale high-temperature heat pumps with supply temperatures ranging from 90 to 160°C, the PUSH2HEAT project aims to demonstrate the viability of high-temperature heat pumps at four industrial sites in Germany, Italy, and Belgium.

The diverse range of technologies showcased in the project promises significant advancements in process steam production, leveraging surplus waste heat to drive efficiency, says Reuven Paitazoglou, Fraunhofer IEG. And even though the project focuses on implementing heat upgrading technologies across the paper and chemical industries, it also lays the groundwork for broader adoption across various industrial sectors.

The project consortium hopes to provide detailed operational data post-commissioning to validate the performance and efficiency of the systems later in 2025.

Key Highlights
