SaskPower Boundary Dam 3 upgrade and CCS: project profile

摘要

Project scope: upgrade of Boundary Dam 3 lignite fired power plant and addition of Shell Cansolv capture technology, the world's first large scale post combustion capture facility at an operating coal fired plant. The installed capacity of the upgraded BD3 pulverised coal plant is around 110 MWe. Estimates of plant efficiency, "energy penalty" associated with carbon capture and storage, etc, are expected to be available early in 2015, by which time the refurbished plant and CCS equipment should be fully operational. The captured carbon dioxide (1 million t/y) is being compressed and supplied to Cenovus for use in enhanced oil recovery (via a 66 km long pipeline) in oil fields near Weyburn. Carbon dioxide can also be piped to a storage demonstration facility 2 km from the power plant (Aquistore).
