TC Energy of Canada sets net zero roadmap
Canadian energy infrastructure giant TC Energy released a new emissions reduction plan on October 26, setting out a roadmap it says would reduce its greenhouse gas (GHG) intensity by 30%. by 2030 and put it on track for net zero emissions from its operations by 2050.
TC Energy CEO François Poirier highlighted the many unknowns of the global energy transition and the lingering uncertainty about which low-carbon solutions will be widely adopted. But he said industry cannot do it alone – political, regulatory and technological support will be needed, especially from governments.
“Governments will need to provide direct financial support for emissions reduction initiatives, emerging low-carbon fuels and infrastructure, and other decarbonization solutions,” he said in the opening comments of the plan. “New technologies need to come to market on a competitive scale and cost. We will adapt and respond as these factors change over the life of our plan. “
TC Energy said it will target five focus areas to reduce the emissions intensity of its operations:
- Modernization of existing systems and assets;
- Decarbonization of its energy consumption;
- Investments in low carbon energy and infrastructure;
- Driving digital solutions and technologies, and;
- Take advantage of carbon offsets and credits.
TC Energy’s emission reduction targets relate to Scope 1 and Scope 2 emissions and primarily focus on reducing CO emissions2, CH4 (methane) and N2O (nitrogen oxide) emissions, all of which are generated largely (71%) by the fuel combustion associated with its pipeline assets. Electricity consumption (Scope 2) represents 11% of TC Energy’s GHG emissions profile, followed by fugitive and leakage emissions (10%) and ventilation and other emissions (8%).
Although Scope 3 emissions are not targeted in the reduction plan, TC Energy said it is tracking and reporting on four categories of Scope 3 emissions – related to fuel and energy not already included in Scopes 1 and 2, operations generated by waste, business travel and upstream leased assets – and is actively working with its suppliers and customers to understand Scope 3 emissions throughout its value chain.
As part of the “modernization” point, TC Energy says it will manage emissions by improving its leak detection and repair programs, install waste heat recovery units on compressors and pilot new technologies and innovations. equipment for capturing exhaust emissions.
It is actively working on a plan to modernize its Columbia gas transmission system in the United States, where $ 2.5 billion has been invested in improving the system since 2013. Since then, cumulative avoided emissions have reached 258,000 tonnes of CO.2e (mtCO2e), and on the basis of the work carried out, the annual emissions avoided should be on average 57,000 mtCO2e.
To decarbonize its energy use, TC Energy, like many in the Canadian oil and gas industry, is turning to renewables to power as many of its systems as possible.
“Our liquid systems use a fleet of electric pumps and we are making plans to provide renewable energy for this fleet,” the roadmap reads. “There is little or no change in the equipment or infrastructure required to switch to renewable energy, and the pipeline right-of-way crosses many geographic areas well suited to wind or solar power. “
Once all of its liquid pipeline assets in the United States and Canada are powered by renewable energy, the roadmap says, GHG reductions could reach 2 million tonnes per year.
The primary contributor to TC Energy’s GHG emissions, however, are compressors in its gas pipelines, many of which run on natural gas. These compressors are gradually being replaced by electric drive units, with 10% of the compressor fleet in Canada and 5% of the fleet in the United States now powered by electricity – but it doesn’t stop there.
“To further reduce the emission intensity of our gas pipeline operations, we are exploring the possibilities of supplying our electric compressors with renewable sources,” says the roadmap. “The experience we gain in sourcing renewable energy for our liquids pipelines will allow us to implement a similar approach for our natural gas pipeline operations in the United States and Canada. ”
Finally, TC Energy said it will continue to invest in low-carbon energy and infrastructure, building on its recent plans for an Alberta carbon grid that capitalizes on expanding opportunities. of Carbon Capture, Use and Storage (CCUS) and its plans to develop hydrogen. production assets in Atlantic Canada with Irving Oil.
