Klemetsrud CCS

The Hafslund Celsio Carbon Capture Project is a large-scale post-combustion CO₂ capture initiative at the Klemetsrud waste-to-energy plant in Oslo, Norway, operated by Hafslund Celsio, the country’s largest district heating supplier and waste incinerator. The project is part of Norway’s Longship full value-chain CCS program and will install a modular carbon capture facility based on SLB Capturi’s Just Catch™ 400 unit to extract CO₂ from the plant’s flue gas, liquefy and temporarily store the CO₂ onsite, and prepare it for export. Captured CO₂, expected to be approximately 350,000 metric tonnes per year once operational, will be transferred via ship from Oslo harbor to the Northern Lights permanent storage facility on the Norwegian continental shelf for geologic sequestration. The engineering, procurement, construction, installation, and commissioning (EPCIC) contract for the project was awarded jointly to SLB Capturi (a joint venture of SLB and Aker Carbon Capture) and Aker Solutions, with delivery of the capture plant, CO₂ liquefaction and storage systems, intermediate storage, and harbor loading infrastructure. The facility is expected to be operational by the third quarter of 2029, representing one of the first full-scale carbon capture deployments on a waste-to-energy site in Europe and a key contributor to Oslo’s emissions reduction strategy.
