Klemetsrud (Oslo) waste management and energy recovery CCS project
Oslo Municipality has a stated philosophy that aims to contribute to a CO₂ capture and storage (CCS) project at the waste management and energy recovery plant at Klemetsrud.
The Klemetsrud plant recycles household and commercial waste from Oslo, neighboring communities and other waste. The heat energy from the incineration of waste is used to produce hot water, which is utilized in Oslo's district heating systems and the production of electricity.
The Klemetsrud plant AS (KEAS) was demerged from Oslo municipality department for waste management for energy (EGE) June, 2015.
KEAS is Norway's largest energy recovery, and was put into operation in autumn 1985 with new extensions in recent times. The plant recovers the energy from waste industry players at home and abroad, to environmentally friendly district heating and electricity. The plant is operated 24 hours a day, 365 days a year.
The CCS project
The total emissions from the Klemetsrud system represent in excess of 10 percent of the municipality's total greenhouse gas emissions. This is comparable to the annual emissions from about 60,000 cars.
If CO₂ emissions from the Klemetsrud plant can be reduced by 2020, this will be a significant contribution to Oslo's climate targets for 2030 and 2050. It can also be the world's first full-scale CO₂ capture associated with energy recovery.
Capture of CO₂ emissions partly biological in origin means that CO₂ is taken out of circulation and the atmosphere, making it so-called carbon negative. There is broad consensus that carbon negative technology must be developed and used in this century to avoid dangerous climate change.
The idea of capturing carbon from flue at KEA AS was born during a strategy process in EGE in 2014. In February 2015 suggested Bellona in its CO2 –economy report KEA AS as part of a CCS industry cluster in the eastern part of Norway. In the Gassnova study spring 2015 KEAS was recommended as one of three candidates for the establishment of a national full-scale carbon capture facilities. In June, the city council agreed to establish a test facility for carbon capture at Klemetsrud and KEA AS has put the plant at the disposal of such a test facility. The test facility opened in January 2016. The feasibility study will be delivered Gassnova in May 2016.
Important now will be to ensure further development of the CCS project at Klemetsrud. Potentially it can be a significant contribution to the commitment of the Parliamentary climate agreement on a full scale plant for CO₂ capture by 2020.
