Radboud University is investing in renewable energy for the next 20 years

Radboud University is currently working hard on a major upgrade to its sustainable energy system on campus. This involves thermal energy storage, better known as TES, a smart system that stores heat and cold in the ground. This upgrade will enable the university to make even greater savings on gas and to benefit from a future-proof, sustainable energy supply over the next two decades.

Heat and cooling from the ground, for the whole campus

Radboud University’s thermal energy storage system has been in operation for twenty years and originally began as an energy supply for the Huygens Building alone. The system has since grown to become the backbone of the campus energy network (HEN): no less than 90% of the university’s buildings are now connected to it. By making smart use of the heat and cold stored in the ground, gas consumption on campus has fallen significantly in recent years

Expansion and modernisation

Now that the system is twenty years old, it is time for maintenance and an upgrade. Two new wells are being drilled, one on the hot side and one on the cold side, to a depth of around 75 metres. This brings the total to six wells on each side. The installations and control technology are also being simplified and optimised, making the system easier to manage. And space has already been set aside for a potential seventh well in the future, should demand continue to grow.

In phases, with minimal disruption

This project is a collaboration between Campus & Facilities and a number of specialist technical partners. Work began in early 2026. Technical rooms are currently being fitted out at the Greenhouses of the experimental garden & gene bank and in the basement of Mercator II. Drilling for the new wells will take place in May and June. As the system must remain operational at all times, all work is being carried out in careful phases. The first phase is expected to come into use in August or September. The works, which will continue until November, will cause minimal disruption to campus users.
