Annex 58 High-Temperature Heat Pumps Final Report
The decarbonization of industrial process heating is a top priority to achieve climate goals as process heating accounts for a considerable share of the final energy consumption and greenhouse gas emissions of industries. High-temperature heat pumps are a promising alternative to fossil fuels to provide process heating at the highest efficiency using potentially emissions-free electricity. However, the deployment of heat pumps for temperatures above 100 °C is still limited. Enabling a large variety of industries to convert their process heat supply to high-temperature heat pumps requires a common understanding of the technology, its potentials, and its perspectives.
