In order to take concrete steps towards decarbonisation, the Norwegian government has launched a Carbon Capture and Storage (CCS) project. The City of Oslo is aiming for a 50% reduction in greenhouse gas emissions by 2022 and a 95% reduction by 2030. The CCS project at Fortum Oslo Varme’s Klemetsrud waste-to-energy plant is the single most important initiative to achieve the target.
Launched in August 2018, the CCS project at the Klemetsrud waste-to-energy plant is currently in the preliminary planning phase. The plant uses municipal waste in the production of electricity and heat. Because the waste cannot be recycled or recovered as material, using it in energy and heat production reduces the amount of waste ending up in landfills. The process removes hazardous gases and other substances, but still produces carbon dioxide emissions. The problem can be solved using CCS technology that is already in use in Canada.
Fortum Oslo Varme’s plan is to capture 400,000 tonnes, i.e. 90%, of the waste-to-energy plant’s CO₂ emissions. In the plan, the captured carbon dioxide is converted into a liquid form, transported to a port, and shipped to an intermediate storage on the west coast of Norway. Finally, in collaboration with partners (e.g. Equinor), the CO₂ is pumped below the seabed and stored in old, depleted oil and gas reservoirs. In addition to the CO₂ from Norway, the reservoirs can also be used to store liquefied carbon dioxide from other European countries.
The Oslo CCS project’s target is to submit the final project plan to the Norwegian government in August 2019. The Parliament’s decision on the matter is anticipated in 2020 or 2021. The project is expected to be launched in 2023 or 2024.
