Klemetsrud Waste-to-Energy Carbon Capture (CCS)
Hafslund Oslo Celsio is fitting Norway's largest waste-to-energy plant — source of 17% of Oslo's direct emissions and much of its district heating — with carbon capture. Paused in 2023 over rising costs, the project restarted after a January 2025 investment decision; construction is underway, targeting startup in Q3 2029, with captured CO2 shipped to offshore storage.
📊 Impact
Designed to capture 350,000 tonnes of CO2 a year — about 90% of the flue-gas CO2 from the plant, roughly 200,000 tonnes of it biogenic and so counted as negative emissions — once construction finishes; this is a planned/design capacity, not yet a measured operating result, since the capture facility itself has not been built. Captured CO2 is to be piped to the state-backed Northern Lights terminal for offshore storage under the North Sea.
🎓 Lesson
A state-backed climate flagship can still stall for years on cost overruns alone: Klemetsrud's technology was never the obstacle — its 2023 pause and 2025 restart came down entirely to who would cover a bigger bill.
