2nd Generation CCS

 


Studies

The International CCS Knowledge Centre experts spearheaded a feasibility study to retrofit SaskPower’s Shand Power Station, (Shand) a 300 – MW, single unit, coal-fired power plant that has double the capacity of Boundary Dam 3 CCS Facility (BD3) with a large-scale, CCS facility.

Key Hightlights of the Shand CCS Feasibility Study (Shand Study):
  • The study shows that compared to the Boundary Dam 3 CCS project (BD3), a CCS system at Shand could see capture capital cost reductions of 67% per tonne of carbon dioxide (CO2 ) captured as well as 92% in potential savings to power plant integration capital cost.
  • Based on the model, the levelized cost of captured CO2 is calculated at $45US/tonne.
  • Second generation CCS can capture more emissions at lower loads (i.e. power generation) such that more than a 90% capture rate is possible. This means that CCS has the potential to integrate well with renewables which provide a varying load. CO2 capture rate could be up to 97% at 62% electrical load.
  • The Shand CCS system would be designed without the requirement of additional water, mitigating a key constraint for thermal plant operation retrofits and expansions.
  • At this site, up to 140,000 tonnes per year of fly ash would be saleable to the concrete market (subject to demand), which could offset emissions in concrete production. This equates to a potential net reduction of 125,000 tonnes of CO2 each year resulting in a facility with net-negative CO2 emissions.
  • The Shand CCS project design capacity is nominally 2 million tonnes of CO2 captured per year – twice the initial design capacity of BD3 (this economy of scale reduces costs).
