A consortium led by ETH Zurich has begun planning work for a possible CO2 injection test. During the exploratory phase, the aim is to clarify whether CO2 can be injected underground through a disused Nagra borehole in Trüllikon ZH.
During the exploration phase, the local subsurface will be examined in depth using seismic measurements, among other things, as announced by ETH Zurich on Thursday. The pilot project CITru (CO2 pilot injection in Trüllikon) is intended to provide information on how much CO2 can be stored underground and what the potential technical, regulatory and social hurdles are.
At the Trüllikon site, Nagra's data and experience can be drawn on. The borehole was drilled as part of the search for possible sites for a nuclear waste repository.
The exploration phase will last until the end of 2025. If the project proves to be sufficiently safe, environmentally friendly and financially viable, the implementation phase will be launched. CO2 would be injected into the ground in 2026 at the earliest.
The long-term storage of CO2 underground could help to achieve the goal of net-zero greenhouse gas emissions by 2050.
