CCS facility at Boundary Dam captured more than 48,000 tonnes of CO2 in April

The carbon capture and storage (CCS) facility at SaskPower’s Boundary Dam Power Station captured 48,150 tonnes of carbon dioxide (CO2) in April, according to information released by SaskPower on Wednesday.

The average daily capture rate when CCS was online was 2,293 tonnes, with a peak one-day capture rate of 2,804 tonnes. The total of 48,150 tonnes was about 50 per cent of the capacity for the facility.

The CCS facility was online 67 per cent of the month, coming offline for a total of 237 hours to accommodate a 10-day outage at the BD3 power unit. The previous 12-month average was 76.7 per cent, but that includes April 2019, when the CCS facility was offline for the entire month due to a scheduled outage.

Last month's outage was unplanned, as BD3 had a number of tube leaks in late March and early April, and the outage was required to change out several sections of boiler tubes.

Unit 3 also produced an average of just under 90 megawatts of power a day.

A total of 226,670 tonnes of CO2 were captured in the first four months of this year, and 3,308,122 tonnes of CO2 have been captured since the CCS facility went online in October 2014.
