Shell sold millions of carbon credits for reductions in greenhouse gas emissions that never happened, allowing the company to turn a profit on its fledgling carbon capture and storage project, according to a new report by Greenpeace Canada.
Under an agreement with the Alberta government, Shell was awarded two tonnes’ worth of emissions reduction credits for each tonne of carbon it actually captured and stored underground at its Quest plant, near Edmonton.
This took place between 2015 and 2021 through a subsidy program for carbon, capture, utilisation and storage projects (CCUS), which are championed by the oil and gas sector as a way to cut its greenhouse gas emissions.
At the time, Quest was the only operational CCUS facility in Alberta. The subsidy program ended in 2022.
Carbon capture is basically a form of energy storage. If it’s energy that we wouldn’t otherwise be able to capture, or if it’s more energy than we need for consumption at a given moment in time, then it makes sense to store it instead. I don’t know enough to say if these would apply in practice, but it’s plausible that it’s better to capture than to use the energy.
