Surroundings and process

Geothermal energy on the TU Delft campus has two goals: 

Warming buildings sustainably: In phase 1, the TU Delft buildings will be connected to the geothermal source. In the future (phase 2), other locations within the municipality of Delft will be connected to the source. 

Research and innovation: Its necessary to apply the technology on a large scale and cost efficiently. TU Delft is investigating how this can be done. That is why the geothermal wells on the campus are equipped with measuring equipment and are closely monitored, so that the researchers can verify their models and theories in an operating system.


After consulting with the municipality, province, water board and SSM and advice from experts such as TNO, RVO, the Ministry of Economic Affairs has granted an Exploration Permit. See the image of the jump area Pijnacker-Nootdorp 6a, which falls under the exploration permit. 

Research has been carried out into the underground. These are geological studies, not actual drilling. With this research, the potential and opportunities of geothermal energy are accurately mapped out. These results have been evaluated, among others, with the municipality of Delft, the Ministry and Het Waterschap. 

An EIA notification has been submitted to the Ministry of Economic Affairs. This notification serves as a check to see if the project has no significant negative effects on the environment. The decision has been made that no environmental impact report needs to be drawn up. 

The destination-plan of the municipality of Delft must be amended. Preparations for this have already started. Interested parties, including local residents, may submit their views. The technical design has been completed and the required materials as well as the required quantities are known. 

An environmental permit is required for the above-ground aspects, such as the execution of the two geothermal drillings and the realization of the production facilities. The Ministry of Economic Affairs decides on this. They will ask advice on this matter from the State Supervision of Mines, the municipality, the province and The Waterschap. Interested parties, including local residents, may submit their views. Due to the flexible turnaround due to long delivery times, the materials can now be ordered. 

The consortium will build the geothermal energy installation at the chosen location. Then the drilling is carried out. Only after the first drillings will we know whether the heat can be extracted.  

To extract geothermal energy, more permits are needed. This concerns, among other things, a production license and production plan. The Ministry of Economic Affairs decides on this matter. The ministry asks for advice from experts, such as the State Supervision of Mines, TNO, the Mining Council, the province, the Technical Committee on soil movement, municipalities and Waterschappen. Stakeholders, such as local residents, can submit their views on the draft decision of the production plan. After this phase, the above-ground facilities and installations will be placed and connected. 

The well is connected to the heat network. The geothermal energy heats the buildings that are connected to the heat network. In the first phase, the TU Delft buildings will be heated and in the built and in the second phase, by means of the Open Warmte Delft project, houses and company buildings will be heated with sustainable energy from our own soil.
