The carbon capture and storage (CCS) facility at SaskPower’s Boundary Dam Power Station returned to service on Dec. 7 after its scheduled outage that started in mid-November.
For the month of December, the facility captured 57,590 tonnes of carbon dioxide (CO2) for a total of 616,119 tonnes captured in 2019. The average daily capture rate in December was 2,504 tonnes per day, with a peak one-day capture rate of 2,863 tonnes.
The acid plant also returned to service in late December and produced 104 tonnes of sulfuric acid.
The CCS facility was online 72 per cent of the time, compared with an average of 70 per cent for the previous 12 months.
Unit 3 at Boundary Dam produced an average of about 110 megawatts of power during the month, compared to a previous 12-month rate of 101.3 megawatts.
Since the CCS facility came online in October 2014, it has captured 3,081,452 tonnes of CO2.
Next week’s edition of the Mercury will have more on the past year for the CCS facility.
