IEA ECES Annex 20 - Sustainable Cooling with Thermal Energy Storage - Final Report

Share this Post:

This is the final report of annex 20 of the IEA implementing agreement on Energy Conservation through Energy Storage (ECES)

Renewable and natural energy sources, main components of sustainable energy systems, can only be made continuously available to users through thermal energy storage (TES). In addition to heating TES provides several flexible alternatives for cooling systems.

Recent discussions on topics like global warming and heat waves have brought attention once again to energy efficient cooling systems utilizing renewable energy sources. Cooling demand has already been increasing due to the evolving comfort expectations and technological development around the world. Climate change has brought additional challenges for cooling systems designers.

New cooling systems must use less and less electricity generated by fossil fuel based systems and still be able to meet the ever increasing and varying demand.
