The EU aims to have a net-zero greenhouse gas (GHG) economy by 2050. Large-scale seasonal heat storage is a key strategy to decarbonize heating to achieve EU ambitions. The PUSH-IT consortium receives this Horizon Europe grant to demonstrate and develop such heat storage systems. PUSH-IT stands for Piloting Underground Seasonal Heat Storage In geothermal reservoirs.
PUSH-IT will pilot and develop each of the technologies: ATES in Delft, BTES in Darmstadt and MTES in Bochum, while it also has follower sites for each technology: Berlin, Litomerice (Czech Republic) and Cornwall respectively.
The combination of ATES and geothermal in the built environment is unique in the world and makes the TU Delft stand out internationally. Key innovations developed by PUSH-IT at the Delft site relate to drilling, completion and well design as well as monitoring and testing of the geothermal well, water quality control and system integration/control.
