Avoid Electricity Grid Congestion, Save Energy: Triple Well Aquifer TES Without A Heat Pump

To mitigate global warming, CO₂ emission reduction must be accomplished sector wide. Aquifer thermal energy storage (ATES) doublet systems with integrated heat pumps are a step forward relative to conventional solutions in terms of energy consumption and fossil fuel dependency and are common in The Netherlands. However, heat pumps in such systems are responsible for the majority of the energy consumption and put a significant load on the electricity grid. Both factors can pose challenges in achieving the energy transition and predefined climate goals in a timely manner. ATES triplet systems can mitigate both factors significantly. This research uses a detailed dynamic integral simulation model, which is a transient model that simulates all components simultaneously connected to each other, all to investigate the technical, operational and financial feasibility of an ATES triplet system for a specific case in The Netherlands. The study also focuses on gaining an understanding of the system dynamics of ATES triplet systems. The created simulation model includes models of the solar collectors, dry cooler, ATES wells, heat and cold consumers in the building and a building simulation model.
