The European Plate Observing System – Netherlands (EPOS-NL) is a Dutch national research infrastructure for solid Earth sciences. EPOS-NL is a cluster of large-scale geophysical facilities for research on georesources. It develops innovative research facilities and integrates these with existing, world-class facilities into a coherent infrastructure.
A consortium of partners from the Netherlands, UK, Turkey, Italy and Iceland investigate and demonstrate the potential of re-injecting CO2 into geothermal fields. This consortium program provides the geothermal energy sector with the means to address the climate change challenge through CO2 utilization and storage.
Energy Piles in the Netherlands
The energy piles will warm and cool buildings through their pile foundations by using the natural temperature of the soil. An 18-meters deep hole is drilled in TU Delft’s Green Village, containing detailed instrumentation in the energy pile foundations in order to test and speed up their use on the market. The aim is to standardize the pile technology up to 30-meters-deep and help the industry build more eco-friendly constructions.
In this work, a novel ATES system without a heat pump is proposed which now uses three wells (a triplet), solar heat collectors and a dry cooler. The use of heat pumps is avoided, vastly reducing the electricity required. The basic working principle shows great potential but needs development on robustness and monitoring, and integrated control of the building’s heating and cooling systems, as well as on the processes in the subsurface to ensure system longevity.
Due to large demand for ATES many urban aquifers experience scarcity of space to accommodate the demand for ATES systems. Under current practice ATES wells are placed at large mutual distance. This distance can be reduced when applying a self organization planning governance structure together with a Distributed Model-based Predictive Control (D-MPC).
