Biogenic CO₂ captured from a Norwegian wastewater biogas facility is being permanently stored beneath the seabed in what is claimed as the world's first geological storage project of its kind.
The project, a collaboration between HoopCO2, Inherit Carbon Solutions and Northern Lights JV, began operations on 23 March. CO₂ is captured at 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 in the biogas facility, biogenic CO₂ is released as a natural byproduct, which HoopCO2 captures and liquefies on site.
The liquefied CO₂ is transported by road tanker to Northern Lights' receiving terminal in Øygarden, west of Bergen, and then by pipeline to permanent storage 2,600 metres below the seabed. Northern Lights has provided offshore CO₂ storage commercially since August 2025.
Inherit Carbon Solutions developed the project and contracts the full value chain from capture through to geological storage. The company issues verified carbon removal credits through the Puro.earth registry, making this one of a small number of fully operational, verified permanent carbon dioxide removal projects worldwide.
Kaja Voss, CEO of Inherit Carbon Solutions, said: "For the first time, biogenic CO₂ from biogas production is being permanently stored underground. This proves that the full value chain works, from capture at a biogas facility to permanent storage below the seabed."
