This project builds on IEA HPT Annex 58 (2021 to 2024) and continues Switzer-land’s active participation in the new IEA HPT Project 68 on industrial high-temperature heat pumps (HTHPs) to further strengthen Switzerland’s leadership in this field. Project 68 focuses on higher technology readiness levels (TRL 4 to 9), market uptake, education, and knowledge dissemination. OST-IES will represent Switzerland and leverage the SWEET DeCarbCH initiative as a multipli-er for knowledge and technology transfer (KTT). Key objectives include participation in international Project 68 meetings with experts, analysis of global HTHP technologies and developments, docu-mentation of Swiss HTHP installations, and addressing five core research questions related to market adoption, cost-effectiveness, policy frameworks, technical optimization, and best practices. The project promotes international collaboration, drives innovation, and sup-ports the implementation of Swiss cli-mate policy targe
