Geothermal energy is one of the promising energy resources of the future. TU Delft engages in the installation of a geothermal doublet on campus (the DAP-Well). DAPwell will offer a unique full scale research infrastructure of international significance, as it provides access to an operating geothermal system. Equipped with a broad range of advanced technologies for monitoring and data acquisition, DAPwell will deliver essential information on processes affecting deep geothermal energy provision. DAPwell is closely linked with the Dutch Large Scale Research Infrastructure EPOS-NL that was awarded more than 12 million euro by NWO. EPOS-NL is the Dutch contribution to the European Plate Observing System (EPOS), the Europe-wide infrastructure of geological sciences, geo-hazards and resources. As TU Delft is proud to be developing a sustainable campus, where electricity is already provided by solar panels on TU buildings and an off-shore wind park. The DAPwell will allow for heating campus buildings with geothermal energy and brings TU Delft a big step closer towards being CO2-neutral.
The department, faculty and university have agreed on long-term investments for the geothermal theme, both for the research infrastructure as for increasing staff capacity (i.e. Dr Maren Brehme, Prof. David Bruhn). The programme is led by Dr Phil Vardon. Currently, the theme hosts 9 PhD candidates and postdocs.
Subsurface storage is a theme which started in 2019, focussing on using permeable underground layers as temporary storage facilities for energy carriers, such as hydrogen, that are becoming increasingly important for a carbon free future. In addition, Our department has a strong track record in Carbon Capture and Storage, which also is part of this theme now. The research focusses on the development and demonstration of safe and reliable technologies for these applications. This theme is lead by Dr Hadi Hajibeygi and is closely linked with his Vidi grant obtained in 2019. Currently, funding for 4 PhD and postdoc positions has been acquired.
Consequences of underground engineering
Consequences of underground engineering is a theme that integrates the projects carried out within the department in the DeepNL programme of NWO. This programme is related to induced earthquakes in the Groningen gas field. The joint efforts in applying for funding in this programme, often in cooperation with Utrecht University and GRS, respectively, have been very successful. We are currently involved in 5 projects with a total of 15 PhD and postdoc positions. The theme is a prominent example of the integration of depth-scales, from the near surface to the deep underground. In the future this theme will be expanded to include the impact of underground activities at the surface, such as subsidence and possible reduction in sub-surface ecosystem services. The theme is currently lead by four Principle Investigators.
