Abstract
Underground Thermal Energy Storage (UTES) on temperature levels above ca. 50 OC is still not done widely today. The development harks hack to the 70s, hut the real breakthrough still has to he made. Nevertheless, some very interesting plants are operational, and a lot of experience was gained through experimental and theoretical work. In a report in IEA ECES Annex 12 this experience is documented, and the needs and opportunities for future R&D and applications are identified. This paper summarises the IEA report and highlights some system opportunities identified within the E A co-operation.
