In collaboration with the Climate Technology Centre & Network
(CTCN), the International CCS Knowledge Centre presented the third of three webinars on the necessity of large scale CCS to meaninfully reduce global CO2
Carbon Capture and Storage (CCS) applied to large point source emissions is the technology that yields the biggest reduction in CO2 emissions. Canada is a leader in CCS, and it needs to be advanced at a greater rate to meet the Paris Agreement emissions reduction targets.
Early in 2018, the Boundary Dam 3 CCS Facility (BD3) surpassed 2Million Tonnes of Captured CO2. Along with this significant milestone, the International CCS Knowledge Centre recently released 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 BD3 with a large-scale, CCS facility.\
Key Highlights of the Shand CCS Feasibility Study (Shand Study):
- The study shows that compared to the 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).
The International CCS Knowledge Centre offers, those looking to advance large scale CCS, the benefit of the essential lessons learned, such as: technical and engineering decisions, models and practices that are critical to ensuring success, and avoiding pitfalls and mistakes – ultimately to reduce the cost and risks to expediate the CCS deployment to mitigate emissions and take climate action.
Corwyn Bruce - Corwyn joined the International CCS Knowledge Centre in August 2017 where he heads the technical team and is the lead author on the Shand CCS Feasibility Study. He brought with him his formidable experience working on the Boundary Dam 3 CCS project since early 2009. During this time, he served as both an engineer and a project manager focusing on: building the original business case; scope definition and delivery of the power plant upgrades and capture plant integration; and most recently has spent the past 3 years leading the effort to resolve deficiency and operational issues at the facility. Prior to joining the clean coal initiative, Corwyn spent 5 years with SaskPower leading the control system replacement projects at Poplar River Power Station in 2006 and again in 2008. Previously, he spent 10 years with ABB / Bailey Controls, designing, commissioning and tuning control system upgrades on thermal power plant and industrial facilities in Western Canada.
Beth Hardy - As VP of Strategy and Stakeholder Relations, Beth leads the Knowledge Centre’s considerations of policies and regulations that foster CCS; and focuses on helping to link CCS knowledge with other countries to reduce locked-in investments and collaboratively support the goals of the Paris Agreement. Her understanding of complex climate change matters, capacity building requirements, and international financing concerns act as a solid basis for assisting both national and international implementation strategies for technologies that support environmental targets. Prior to joining the Knowledge Centre, Beth worked briefly as legal counsel for the provincial Crown utility. She pairs this industrial perspective with regulatory knowledge as Acting Director of Climate Change with the Government of Saskatchewan. These positions are reflective of Beth’s time with the National Round Table on the Environment and the Economy where she focused on analysing provincial/territorial climate action plans and making recommendations for low cost and sustainable pathways. Beth’s legal education, teaching and practice have explored balancing energy, the environment and social implications.
