The carbon capture and storage (CCS) facility at the Boundary Dam Power Station performed well after it came online again in May.
It returned to service on May 7 after a 58-day maintenance outage. The tasks during shutdown included the first major overhaul of the carbon dioxide (CO2) compressor since the CCS facility began operating in October 2014.
After final compressor system checks, the facility returned to continuous service on May 12.
For the month of May, the CCS facility captured 48,203 tonnes of CO2, which was about 48 per cent of its capacity. The facility’s 12-month average for CO2 captured is about 32,000 tonnes.
It was also online 65 per cent of the month, compared to the previous 12-month average of 55.7 per cent.
Average power produced was just shy of 120 megawatts, which was well above the previous 12-month average of 77.8 megawatts.
The peak capture rate was 2,734 tonnes per day.
Since the CCS facility went online in 2014, more than 2.64 million tonnes of CO2 have been captured. A total of 178,911 tonnes have been captured so far this year.
