Publications
The researchers of the Geological Survey of the Netherlands (GDN) are continuously publishing their research results in various forms. You can find these publications via the TNO website and NLOG website, where technical publications and posters are stored in a RefShare database.
We have selected a few of the many publications for you on this page.

Report: ‘KEEN Evaluation of the effects of the Middenmeer HT-ATES on groundwater quality’
In the Knowledge of Ecology for the Energy Transition (KEEN) programme, knowledge organisations Deltares, KWR, TNO and Wageningen University & Research (WUR) are researching the consequences of the energy transition for animals, plants and their habitats. The knowledge gained from the KEEN programme helps organisations working on the energy transition to minimise the negative impacts on nature as much as possible.
As part of this programme, TNO Geological Survey of the Netherlands investigated whether heat storage above the legal limit of 25°C is safe in High Temperature Aquifer Thermal Energy Storage systems (HT-ATES). The aim is to increase efficiency. Monitoring at the HT-ATES in Middenmeer (North Holland) shows that heating primarily leads to the upwelling and mixing of deep, salty groundwater and shallow, less salty groundwater. Further changes in the geochemical composition and microbiology appear to be limited. The results demonstrate that a good understanding of groundwater flow and composition is important.
Summary of the advice on gas extraction at Ternaard
On 28 November 2025, the Minister informed the House of Representatives that gas extraction in the Wadden Sea from Ternaard would not go ahead. This summary provides a public-friendly explanation of the two pieces of advice issued by TNO in 2024.
