Heat losses in ATES systems: The impact of processes, storage geometry and temperature

The technical and economic success of an Aquifer Thermal Energy Storage (ATES) system depends strongly on its thermal recovery efficiency, i.e. the ratio of the amount of energy that is recovered to the energy that was injected. Typically, conduction most strongly determines the thermal recovery efficiency of ATES systems at low storage...

Reactive transport modelling of push-pull tests: A versatile approach to quantify aquifer reactivity

Push-pull tests (PPTs) were evaluated with 1-D radially axisymmetric multi-component geochemical reactive transport modelling (RTM) to assess aquifer reactivity controlling groundwater quality. Nutrient fate and redox processes were investigated in an Aquifer Storage and Recovery (ASR) system, in which oxic tile drainage water (TDW; nitrate ...

Increasing market opportunities for renewable energy technologies with innovations in aquifer thermal energy storage

Heating and cooling using aquifer thermal energy storage (ATES) has hardly been applied outside the Netherlands, even though it could make a valuable contribution to the energy transition. The Climate-KIC project “Europe-wide Use of Energy from aquifers” – E-USE(aq) – aimed to pave the way for Europe-wide application of ATES, through the...

ATES systems in aquifers with high ambient groundwater flow velocity

Aquifer thermal energy storage (ATES) is a technology with worldwide potential to provide sustainable space heating and cooling using groundwater stored at different temperatures. In areas with high ambient groundwater flow velocity (>25 m/y) thermal energy losses by displacement of groundwater may be prevented by application of multiple...
