To reduce global warming, the European Union aims to have a net-zero greenhouse gas economy by 2050. At present, heating and cooling represent around half of the final energy demand in Europe. This energy is mainly supplied by fossil fuels. To achieve EU ambitions, is therefore essential to move to low-carbon heating and cooling. A challenge for decarbonizing heat systems is the seasonal mismatch between demand for heat and heat generation from sustainable sources. In summer, more heat is generated than used; whilst in winter, heat generation cannot meet the high demand. Increasing capacity for heat production would meet peak heat demans. However, this would not be cost effective, as most of the installed capacity will not be used. Alternatively, the storage of thermal energy for later use when production exceeds demand would account for the seasonal mistmatch. Various technologies have been proposed for large-scale heat storage in geothermal reservoirs and low temperature storage is routinely applied. A number of projects, inclduing the H2020 funded PUSH-IT project are focusing on extending storage temperatures, in the case of PUSH-IT, up to 90 °C.
