Canada’s heavily polluting oil sands development in Alberta may seem an unlikely place for a green revolution, but that is exactly what the Canadian government is trying to advance by setting the region up as a leader in carbon capture and storage (CCS) technology.

While Alberta’s geological make-up is amenable to the use of CCS due to its underground reservoirs, the cost of developing the technology is still extremely high. CCS costs are estimated at around $100 per tonne of carbon dioxide (CO₂
