Sask Power CCS reaches milestone

Canada’s SaskPower's Boundary Dam Carbon Capture plant has captured more than one million tonnes of CO2 since start-up in October 2014.

The milestone reached last month was reached following some hiccups at the facility over the last three years, which had hindered its potential to decabonise.

The CCS project captured 488,300 tonnes of carbon dioxide in the first seven months of 2016, 62,200 more than captured in all of 2015, said SaskPower in its July update on the BD3 CCS project. With the capture of 76,546 tonnes in July, the plant has captured a total of 1,028,000 tonnes of CO2 to date.

“This means the carbon capture unit has surpassed the capture of a million tonnes of carbon dioxide since it began operations in October 2014,” the utility said in a press release. The $1.5-billion CCS plant’s initial nameplate capacity was one million tonnes of CO2 per year, but after a series of production glitches and technical hiccups, the target was reduced to 800,00o tonnes per year. 

Leader Post online reported that in 2014, the plant captured 113,600 tonnes of CO2 from October to the end of the year. In 2015, the facility captured 426,100 tonnes of CO2. 

In June, SaskPower encountered problems with the amine used in the plant’s capture process being affected by heat and coal particulates, but the corporation’s July update suggests the issues have been addressed.

The process remains on track to capture 800,000 tonnes in 2016, the corporation said. SaskPower also continues to meet federal emission regulations and the needs of its CO2 offtaker, Cenvous Energy.

In 2012, Cenovus contracted with SaskPower to supply it with up to 100 per cent of the CO2 produced for the company’s enhanced oil recovery (EOR) project in Weyburn. 

The renegotiated contract now calls for Cenovus to take anywhere from 50 to 99 per cent of the roughly 3,400 tonnes CO2 the plant produces per day.
