The carbon capture and storage (CCS) facility at the Boundary Dam Power Station was operating well in March before a scheduled shutdown took it offline.
It captured 22,357 tonnes of carbon dioxide (CO2) last month, and was online 32 per cent of the month. It was taken offline March 11, as planned maintenance began. The work is expected to take 60 days to complete.
The CCS facility has been online an average of 61.4 per cent of the time during the past 12 months.
The volume of CO2 captured was 22 per cent of the facility’s capacity, and below the 12-month average of 43,820 tonnes.
The one-day peak for CO2 captured was 2,359 tonnes.
It also averaged 105 megawatts of power produced in March, which is better than the 12-month average of 85 megawatts.
A total of 2,596,042 tonnes have been captured at the facility since start-up in October 2014, including 130,709 tonnes so far this year.
