Carbon capture: Hafslund Celsio

Hafslund Celsio (earlier Hafslund Oslo Celsio) plans to capture  up to 400 000 tonnes of CO₂ from their waste-to-energy in Oslo.

Construction phase of Hafslund Celsio was entered in summer 2022, but set on hold spring 2023 after increased cost estimates. So the project is currently considering cost reduction potential, including doing a new FEED study.

Hafslund Celsio: How

At Hafslund Celsio residual waste that cannot be recycled is burned. So the recovered heat produces heat to the residential customers and electricity. Capturing the carbon that is emitted during this process contribute to solve the climate problem associated with Wast-to-Energy activities.

An updated cost estimate from Hafslund Celsio shows that the carbon capture project at the Klemetsrud site will exceed the maximum budget for the project. Celsio ihas placed the project on hold and are working reduce costs.

Negative emissions

Bioenergy with carbon capture and storage (BECCS), is considered to be one of the most prominent of the various negative emissions techniques. Model scenarios that limit global warming to 1.5 or 2 degrees C typically rely on large amounts of “negative emissions”.

Treatment of waste at the WtE plant creates emissions of about 400 000 tonnes of CO₂ per year. Altogether approximately 60% of the emission is based on biogentic sources.

Celsio’s carbon capture will therefore remove approximately 200 000 tonnes of CO₂ from the carbon cycle every year.

Ambitious climate goals

Celsio is jointly owned by Hafslund Eco (60%), Infranode (20%) and HitecVision (20%). Celsio is a leading clean-energy company that provides its customers with electricity, heating and cooling as well as smart solutions to improve resource efficiency. The City of Oslo has ambitious climate targets and needs CO₂ capture at the waste-to-energy plant to reach its goal. The carbon capture project is also strongly rooted in the company’s strategy.
