EPOS-NL is a cluster of large scale facilities, specialist laboratories, and data centres, dedicated to undertake research that serves societal needs for supply of natural resources, and for protection and warning against geo-hazards. EPOS-NL facilities can be used to study the stability and safe utilisation of the Dutch subsurface, addressing natural and human induced earthquakes, subsidence and relative sea level change, geothermal energy, subsurface energy and waste storage, and the future construction of subsurface infrastructure. EPOS-NL consists of a unique integration of multi-scale observational, laboratory, numerical modelling and large-scale subsurface experimental facilities.

EPOS-NL is the Dutch contribution to the European Plate Observing System EPOS, a network of research infrastructures for solid Earth science, that facilitates the integrated use of data, data products and multi-scale laboratories. As such it provides services for scientists in the Netherlands and Europe. EPOS-NL is part of the national roadmap for large scale research facilities. 

The EPOS-NL consortium consists of Utrecht University (in the role of coordinator), the Royal Netherlands Meteorological Institute (KNMI) and TU Delft. 

The EPOS-NL facilities located at TU Delft are the petrophysics lab and a geothermal well. Both facilities are involved in the research theme of Geothermal Science & Engineering of the Department of Geoscience & Engineering. This theme has been established in 2017 and is growing steadily. It connects all researchers working on this topic in the department and faculty.
