As part of the European Sustainable Energy Week (EUSEW) 2026, the RE-WITCH project participated in the 2Cool2Waste Cluster Webinar “The Future of Energy Efficiency: Practical Solutions for Heat Recovery and Electrification”, which took place online on 19 June 2026 from 10:00 AM to 12:00 PM (CET).
Bringing together seven Horizon Europe projects, the 2Cool2Waste cluster webinar provided a comprehensive overview of innovative solutions supporting Europe’s transition towards more sustainable, energy-efficient, and decarbonised heating and cooling systems.
Organised within the framework of EUSEW 2026, the webinar served as a common entry point into key challenges and opportunities related to industrial decarbonisation, energy efficiency, electrification, and net-zero technologies. Through thematic panel discussions, participants explored practical strategies and technological advances addressing both industrial and societal heating and cooling needs.
A collaborative European approach to sustainable heating and cooling
The webinar highlighted how collaborative European research and innovation projects contribute to reducing greenhouse gas emissions, improving thermal energy management, and enhancing energy efficiency across Europe.
Researchers, industry representatives, policymakers, and energy stakeholders exchanged knowledge and discussed concrete solutions related to:
- Heat recovery and heat reuse
- Electrification of heating and cooling systems
- Thermal energy management
- Industrial and district heating and cooling networks
- Flexible and integrated energy systems
- Net-zero industrial technologies
Webinar programme
❄️ Panel 1 – Cooling without wasting energy: can heat help us cool?
This session introduced innovative approaches developed by the THERMINATOR and RE-WITCH projects to recover and reuse waste heat for sustainable cooling applications.
⚡ Panel 2 – Heat pumps: turning low-temperature heat into useful energy
The GEOSYN, SUSHEAT, and EXQUISHEAT projects presented solutions based on advanced heat pump technologies designed to valorise low-temperature heat sources.
🏙️ Panel 3 – Energy systems working together: buildings, grids and flexibility
The SEEDS and SENERGY NETS projects discussed integrated approaches improving energy flexibility and interoperability between buildings and energy grids.
The webinar recording and presentation slides are now available for participants who missed the event or would like to watch it again and revisit the key discussions and insights shared during the session.
About EUSEW 2026
The European Sustainable Energy Week (EUSEW) is the European Union’s flagship annual event dedicated to renewable energy and energy efficiency. Organised by the European Commission’s Directorate-General for Energy and the European Climate, Infrastructure and Environment Executive Agency (CINEA), EUSEW brings together public authorities, industry actors, researchers, NGOs, and citizens to discuss the future of Europe’s clean energy transition.
The 20th edition of EUSEW took place in a hybrid format, both onsite in Brussels and online, from 9 to 11 June 2026, featuring a high-level Policy Conference, the European Sustainable Energy Awards, the Energy Fair, the European Youth Energy Day, and numerous Sustainable Energy Days organised across Europe and beyond.
The recording of this session is now available, together with the presentation.
