A new project in Norway has begun permanently storing biogenic carbon dioxide captured from a wastewater biogas facility beneath the seabed, marking what is being described as a world-first initiative, Bioenergy Insight reported.
The project, led by HoopCO2, Inherit Carbon Solutions and Northern Lights JV, started operations on March 23.
Carbon dioxide is captured at the Veas wastewater treatment plant in Slemmestad, which serves over 800,000 residents in the Oslo region. The CO₂ is produced naturally during the breakdown of organic waste in the biogas process and is captured and liquefied on site.
It is then transported by tanker to a receiving terminal in Øygarden, near Bergen, before being sent through a pipeline for storage about 2,600 metres below the seabed. Northern Lights has been offering offshore carbon storage services since August 2025.
Inherit Carbon Solutions developed the project and manages the full chain from capture to storage. The company also issues certified carbon removal credits through the Puro.earth platform, placing the project among a small number of fully operational permanent carbon removal efforts globally.
Chief executive Kaja Voss said the initiative demonstrates that the entire process — from capturing emissions at a biogas plant to storing them deep underground — can work effectively at scale.
