Spotlight on: Methane emissions reductions
We have been a driving force in the pipeline industry on developing and implementing new practices and technologies to reduce fugitive emissions during routine operations and maintenance.
During maintenance, the use of pull-down compressors (such as the one pictured on the left) and hot tap procedures help us capture and recycle methane emissions. During operation, our Fugitive Emissions Inspection and Leak Repair Program enables us to identify leaks on pipeline and compressor station valves and other components to help reduce releases of natural gas.
We are investing in new technology in our operations to improve tracking of our natural gas pipeline fugitive emissions data at valve sites, meter stations and compressor stations. The technology will improve operations and regulatory reporting activities resulting in improved ability to plan maintenance activities.
Environmental innovation: First-of-a-kind waste heat power generation facility in Alberta
TC Energy is developing a new project that will use the heat produced at one of our compressor stations in southern Alberta to generate electricity. Working in partnership with Siemens, the project will use supercritical carbon dioxide as the working fluid to capture waste heat from the gas-fired turbine and use it to generate emissions-free electricity that will be put into the electricity grid, resulting in greenhouse gas reductions of 44,000 tonnes per year, or the equivalent of taking more than 9,000 vehicles off the road.
Investing in leading-edge technology
TC Energy is pursuing a novel, utility-scale solar-plus-storage electricity generation facility near Aldersyde, Alberta, with support from Emissions Reductions Alberta. The project will use state-of-the-art bifacial solar panels that are double-sided to take advantage of the indirect sunlight from reflective ground cover such as snow-covered surfaces found in Alberta during the winter months. Flow battery storage technology would also allow the solar energy to be stored for up to eight hours for use at times of peak electricity demand.
The innovative project will provide direct GHG benefits through the generation of emissions-free renewable power to meet the needs of 3,000 homes. The project will also help prove the technical and commercial viability of these technologies for wider scale adoption.
