In April 2022, the Dutch gouvernment made €42 million available from the National Growth Fund for preparatory work of the ET and also reserved €870 million for construction. As the Einstein Telescope is an international project, the Netherlands, Belgium and Germany are cooperating in feasibility studies for the telescope in the Meuse-Rhine Euroregion. For example, studies are under way into the differences in planning laws and regulations and their significance for the project. Ultimately, these feasibility studies should lead to a bid book, which will be ready in 2025 at the earliest.

Nevertheless, the sensitivity needed to test Einstein's theory of gravity in strong field conditions or to realize a precision gravitational wave astronomy, mainly of massive stellar bodies or of highly asymmetric (in mass) binary stellar systems, goes beyond the expected performances of the advanced detectors and of their subsequent upgrades. For example, the fundamental limitations at low frequency of the sensitivity of the second generation detectors are given by the

and avoid having an orientation to which the telescope is insensitive, a minimum of two detectors are required. While this could be done with two 90° interferometers at 45° to each other, the triangular form allows the arms to be shared. The 60° arm angle reduces each interferometer's sensitivity,

The low-frequency interferometers (1 to 250 Hz) will use optics cooled to 10 K (−441.7 °F; −263.1 °C), with a beam power of about 18 kW in each arm cavity. The high-frequency ones (10 Hz to 10 kHz) will use room-temperature optics and a much higher recirculating

To circumvent these limitations new infrastructures are necessary: an underground site for the detector, to limit the effect of the seismic noise, and cryogenic facilities to cool down the mirrors to directly reduce the thermal vibration of the test masses.
