In this lecture, we will focus on high-temperature aquifer thermal energy storage (HT-ATES). HT-ATES is a technology that allows for storage of sensible thermal energy in the subsurface with relatively large volumes and for long periods. The use of HT-ATES systems world-wide is still limited. To boost development of HT-ATES in the Netherlands, a research consortium aims to remove technical, legal and commercial obstacles, for systems with storage temperature up to 90°C and subsurface depths up to 500 m-gl. Part of the research program is a converging selection process from 21 quick scans via 7 feasibility studies to 2 or 3 final designs of HT-ATES systems, ready for final investment decisions and legal approval. An overarching analysis of these feasibility studies that were all carried out with similar assumptions and approach, provides insight in key parameters for feasibility. The planned HT-ATES system at TU Delft, as part of the Campus Sustainability Plan, is one of the final cases. Marette will present the potential and state of technology of HT-ATES in the Netherlands, and the key findings of the benchmark study, including the HT-ATES of TU Delft.
Marette Zwamborn is senior researcher and manager of team Energy & Circular Systems at KWR Water Research Institute. This team focuses on research and development of integrated system solutions for a circular economy with renewable energy sources, from a water-related perspective. Marette enjoys working together with experts from various disciplines, to realize innovative interdisciplinary answers to the present challenges of the energy transition. She favours an integrated approach, where technical solutions are supported by appropriate financial, organisational and legal aspects.
Marette has a background in geohydrology and aquifer thermal energy storage systems (ATES). She started her career in drinking water research, continued as a consultant in ATES and industrial water supply, and returned to a research and team management position at KWR in the field of water and energy.
