Subsurface
At TNO we research, develop, orchestrate, and enable cutting-edge innovations that drive the change to net zero.
The TNO Geological Survey of the Netherlands is the knowledge and data centre of the Dutch subsurface and subsurface technologies. We help businesses and governments make well-informed, sustainable decisions about land utilization, subsurface usage and groundwater stewardship.
