Aker Carbon Capture has announced that SLB Capturi, in collaboration with Aker Solutions, has been awarded an engineering, procurement, construction, installation and commissioning contract from Hafslund Celsio AS to deliver a carbon capture solution at their waste-to-energy facility at Klemetsrud, Oslo.

Hafslund Celsio is Norway’s largest district heating supplier and the owner and operator of Norway’s largest waste-to-energy plant. Hafslund Celsio’s carbon capture project is part of Longship, the Norwegian government’s ‘full value-chain’ carbon capture and storage project.

The contract award includes delivery of a carbon capture plant, liquefaction system, temporary storage and loading facility at the waste incineration site. It is based on SLB Capturi’s modularised Just Catch™ 400 unit which has been the basis of several FEED studies including a pulp and paper mill plant in the US as reported recently by the IFRF. It also includes an intermediate CO2 storage and ship loading system at the port of Oslo, from where the CO2 will be transported to the Northern Lights permanent storage facility in the Norwegian sector of the North Sea. The project will start in the first quarter of 2025 and is scheduled to be operational in Q3 2029, capturing 350ktCO2/y.

The award follows a cost reduction phase for Hafslund Celsio’s project, which identified opportunities for efficiencies, including layout optimisation. Reportedly, it was an innovative capture technology design that enabled the project to move forward. It will be delivered based on SLB Capturi’s modularised Just Catch 400 unit.

Egil Fagerland, chief executive officer at SLB Capturi commented that “standardisation and modularisation play a key role in shifting the economics of carbon capture projects. We are extremely proud of our collaboration with Hafslund and Aker Solutions to align our Just Catch plant design with the techno-economic requirements of this project to help make it a reality. We look forward to delivering this flagship project as a successful blueprint for industrial decarbonisation projects in Norway and across the globe.”  

This is a positive outcome for the project following recent uncertainty. And since municipal waste is typically made of more than 50% material from biogenic sources, that portion of the power and heat is recognised as renewable. Applying carbon capture and storage to capture 95% of the emitted CO2 results in a net negative CO2 emission, potentially of the order of over -150ktCO2/y for this project. This makes energy-from-waste plant fitted with CCS a potentially large-scale route for greenhouse gas removal (GGR), with the significant benefit of reducing the amount of non-recyclable waste that would otherwise be sent to landfill.
