Heating and cooling of buildings accounts for ~25% of the primary energy end use, hence is critical to decarbonize. In many climatic conditions heating and cooling systems can be decarbonized using seasonal thermal energy storage to overcome the mismatch in availability and demand [1], with Aquifer Thermal Energy Storage (ATES) being an example sys...

The Dutch research consortium WINDOW has developed and applied a converging selection process to identify preferred locations and integration concepts for HT-ATES in the Netherlands. A longlist of 22 locations was reduced to 7 feasible locations, based on criteria for geological conditions, legal constraints, preliminary business case, planning hor...

The suitability of high temperature aquifer thermal energy storage (HT-ATES) systems, among many other applications in the subsurface, is for a large extent determined by the hydrogeological aquifer properties. Important subsurface properties that are challenging to fully determine in the field are the hydraulic conductivity, the vertical variation...

The primary energy use of ATES systems evaluated for high and low aquifer utilisation levels. • High aquifer utilisation levels reduce energy use of individual systems, as more wells can be placed. • The highest aquifer utilization level considered is 115% and resulted in 82% ATES adoption. • For aquifer utilization <80%, energy use of buildings is...

In the energy transition, multi-energy systems are crucial to reduce the temporal, spatial and functional mismatch between sustainable energy supply and demand. Technologies as power-to-heat (PtH) allow flexible and effective utilisation of available surplus green electricity when integrated with seasonal heat storage options. However, insights and...

In order to assess the thermo-hydraulic modelling capabilities of various geothermal simulators, a comparative test suite was created, consisting of a set of cases designed with conditions relevant to the low-enthalpy range of geothermal operations within the European HEATSTORE research project. In an effort to increase confidence in the usage of e...

The fossil-based energy system is transitioning towards a renewable energy system. One important aspect is the spatial and temporal mismatch between intermitted supply and continuous demand. To ensure a reliable and affordable energy system, we propose an integrated system approach that integrates electricity production, mobility, heating of buildi...

Aquifer Thermal Energy Storage (ATES) systems combined with a heat pump save energy for space heating and cooling of buildings. In most countries the temperature of the stored heat is allowed up to 25-30°C. However, when heat is available at higher temperatures (e.g. waste heat, solar heat), it is more efficient to store higher temperatures because...

Energy consumption for space heating and cooling of buildings can be decreased by 40-80% by use of Aquifer Thermal Energy Storage (ATES). ATES is a proven technique, however, it is not known how efficient currently operating systems are recovering stored energy from the subsurface and how this can be determined with available data. Recent research...
