VANCOUVER — Technological limitations, high costs and infrastructure challenges raise questions about relying on carbon capture, utilization and storage as a cornerstone of federal and Alberta climate policy, according to a new Fraser Institute study. The study argues current carbon capture, utilization and storage technology, commonly known as CCUS, is unlikely to deliver emissions reductions on the scale envisioned by governments and industry. The findings come as Ottawa and Alberta advance plans for a new West Coast oil pipeline alongside development of the Pathways carbon capture and storage project in the oilsands. Kenneth Green, a senior fellow with the Fraser Institute and author of the study, said the historical performance of carbon capture projects raises questions about using the technology as a central climate policy. …It also argues large-scale CCUS projects have frequently failed to meet projected carbon capture targets while experiencing significant cost overruns.
