44.01 has joined the CITru (CO₂ Pilot Injection in Trüllikon) project, an ETH Zurich-led initiative evaluating and planning a CO2 injection test in a Swiss saline aquifer to advance inland geological CO2 storage.

As Switzerland works towards its climate targets, geological carbon storage is being considered as one of several options for managing unavoidable emissions from hard-to-abate sectors and supporting long-term carbon dioxide removal.

The project is investigating the potential for a pilot CO₂ injection through a disused borehole in Trüllikon, Canton Zurich, with implementation planned for 2027, subject to the successful completion of site characterization, regulatory approvals and project development activities.

As a project partner, 44.01 will provide strategic advice on CO₂ injection, subsurface analysis, project implementation and storage site operations. The company will contribute its experience from carbon storage projects and help facilitate the exchange of insights that can inform future deployment efforts.

"Geological carbon storage will play a critical role in achieving global climate goals, and projects like CITru are essential for building the technical knowledge, regulatory frameworks and public confidence needed to scale the industry," said Talal Hasan, CEO of 44.01. "We're excited to work alongside ETH Zurich and other leading partners to support the exploration of onshore CO₂ storage in Switzerland while continuing to broaden our expertise across different storage settings and regions."

The project also strengthens 44.01's presence in Europe and supports the company's long-term ambition to help accelerate the deployment of safe, permanent carbon storage solutions globally. By working with ETH Zurich, one of the world's leading universities for science and engineering, 44.01 will contribute to cutting-edge research while gaining valuable insights into the development of onshore CO₂ storage projects in continental Europe.

The CITru project brings together academic, research and industry partners to evaluate the feasibility of geological CO₂ storage at the site in Trüllikon, Switzerland, and generates knowledge that can support future carbon storage deployment in the country.

About 44.01

44.01 is an award-winning company that permanently stores CO₂ underground. 44.01 takes CO₂ captured from the atmosphere, biogenic sources or hard-to-abate industrial processes, helping decarbonise vital industries and ultimately return the atmosphere to sustainable levels of CO₂. The process is safe, scalable and lasts forever.

About CITru

CITru (CO₂ Pilot Injection in Trüllikon) is a pilot project led by ETH Zurich to assess the feasibility of CO₂ injection in a Swiss saline aquifer through a disused borehole in Trüllikon, Canton Zurich, with implementation planned for 2027. The Federal Offices for Energy, the Environment and National Topography (swisstopo) are supporting the project.
