Shell Canada is going ahead with its Polaris carbon capture project in Alberta.
The company — the Canadian subsidiary of British multinational Shell PLC — announced Wednesday it has made a positive final investment decision on the project, which is designed to capture about 650,000 tonnes of carbon dioxide annually from the Shell-owned Scotford refinery and chemicals complex near Edmonton.
That works out to approximately 40 per cent of Scotford’s direct CO2 emissions from the refinery and 22 per cent of its emissions from the chemicals complex.
Shell did not disclose the dollar value of the Polaris project, but said it is expected to begin operations toward the end of 2028.
“It’s a very good day, it’s an exciting day for us,” said Shell Canada president Susannah Pierce in an interview.
“Certainly for me as country chair of Canada, it’s great to see this capital investment from Shell in Canada. Because as you know, I compete for capital in my portfolio, and I’m pleased that Shell has decided to put it here.”
Shell also announced Wednesday it will proceed with the related Atlas Carbon Storage Hub in partnership with ATCO EnPower. The first phase of Atlas, which will be connected to the Polaris project by a 22-km pipeline, will provide permanent underground storage for CO2 captured by the Polaris project.
Polaris is Shell’s second carbon capture and storage project in Canada. Its first, named Quest, was completed in late 2015 and is also located at the Scotford complex.
That project— which cost $1.3 billion to build — has captured and stored about 1 million tonnes of CO2 annually from the Scotford upgrader since 2015, Shell said.
Shell’s decision to green-light the Polaris project comes just days after a new federal investment tax credit for carbon capture and storage received royal assent.
That tax credit was first announced in 2022, but its recent finalization means that companies can now apply for and claim the credit to offset the capital costs of building carbon capture facilities.
“That (the tax credit) was a critical component of the (Polaris) decision,” Pierce said.
There has been a flurry of carbon capture and proposals in Canada in recent years, though few have received a final investment decision.
Carbon capture and storage, which involves capturing and compressing harmful CO2 emissions from industrial processes and then storing them safely underground, is viewed by many as the best way of decarbonizing heavy-polluting industries such as oil and gas and cement production.
But the technology is very expensive, and corporations have proved uneager to invest in it without significant support from governments.
The largest proposed carbon capture project in Canada, a $16.5-billion proposal by a group of oilsands companies called the Pathways Alliance, has yet to receive a final investment decision.
Earlier this spring, Edmonton-based Capital Power Corp. cancelled plans for its proposed $2.4-billion carbon capture and storage project at its Genesee natural gas-fired power plant. Capital Power said while the project was technically feasible, the economics don’t work.
Pierce said every project is different, but in Shell’s case, Polaris is a “key piece” of the company’s overall decarbonization strategy.
“We have a commitment to decarbonize our Scotford facility, we have experience in CCS (carbon capture and storage) with our years of operating the Quest facility,” she said.
“With the right combination of a fiscal framework as well as regulation, we were able to take a look at CCS compared to any of the other alternatives to meet our compliance obligations, and this one worked.”
