The carbon capture and storage facility at SaskPower鈥檚 Boundary Dam Power Station went through a scheduled maintenance shutdown last month, but prior to that, it was having a very productive month and it even reached a milestone.
As was reported previously by the Mercury, on Nov. 4, the CCS facility at Boundary Dam surpassed three million tonnes of carbon dioxide (CO2) captured since it started up in October 2014.
A scheduled maintenance outage began on Nov. 14 and returned to service Dec. 7. This meant the facility was online 42.2 per cent of November. The average for the previous 12 months was 71 per cent.
The facility averaged nearly 120 megawatts of power produced, which is higher than the 12-month average of 101.1 megawatts of power.聽
During the time it was online, the CCS facility captured 31,401 tonnes of CO2, which is approximately 32 per cent of its monthly capacity. The previous 12-month average was 52,410 tonnes of CO2.
The average daily capture rate was 2,415 tonnes, with a peak one-day capture rate of 2,685 tonnes.
The acid plant was offline for upgrades, so no acid was produced this month.
In the first 11 months of the year, 558,529 tonnes of CO2 were prevented from entering the atmosphere through the CCS process. Since the CCS facility came online, a total of 3,023,862 tonnes of CO2 have been captured.
