March 25, 2026 [Storage Terminals Magazine]- A landmark moment in carbon capture has been achieved in Norway, as the first tank truck loads of liquefied CO2, captured from a biogas facility, have been transported from Slemmestad to permanent geological storage below the seabed. The project, a collaboration between HoopCO2, Inherit Carbon Solutions and Northern Lights JV, represents a global first: the capture and permanent geological storage of biogenic CO2 derived from biogas production.
The CO2 originates from the Veas wastewater treatment plant in Slemmestad, which processes wastewater from more than 800,000 residents across Oslo, Bærum and Asker. As organic material is processed within the biogas facility, biogenic CO2 is released as a natural byproduct. HoopCO2, a subsidiary of Veas, operates the capture and liquefaction facility that makes it possible to collect this CO2 for permanent storage.
Once liquefied, the CO2 is transported by road to Northern Lights’ receiving terminal in Øygarden, west of Bergen, before travelling by pipeline to permanent storage 2,600 metres below the seabed. Northern Lights has been permanently storing CO2 offshore since August 2025, making it the world’s first company to offer CO2 transport and storage as a commercial service.
The permanent storage of biogenic CO2 removes carbon from the natural cycle for good. Inherit Carbon Solutions serves as the project developer, contracting the full value chain from capture through transport to geological storage. The company delivers verified carbon removal credits to end buyers, each certified through the Puro.earth registry. The project is among a very small number of operational, verified permanent carbon dioxide removal projects anywhere in the world.
Kaja Voss, CEO of Inherit Carbon Solutions, described the achievement as a significant milestone. She noted that biogenic CO2 from biogas production is being permanently stored underground for the first time, and that the project demonstrates that the full value chain — from capture at a biogas facility to permanent storage below the seabed, is fully operational.
