Reducing our emissions from operations In 2023-24, we achieved year-over-year GHG emissions reductions of 8,000 tonnes CO 2 e, which is equivalent to taking more than 1,800 vehicles off the road. Contributing to this result was more efficient and prioritized compressor operation during 2023-24 and vent capture technology that is realizing further emissions reduction benefits. In addition, reported gas line flaring and venting decreased, and improvements to data measurement have resulted in more accurate emissions reporting. Installing emissions reduction devices to capture vent gas and save on fuel costs SaskEnergy has been installing emissions reduction devices on our compressors since 2016. These devices capture vent gas and redirect it into the engine air intake for use as a supplemental fuel source. In addition to the emissions reductions that are achieved through this technology, it also decreases the amount of fuel needed to operate the compressors. SaskEnergy now has 30 compressors outfitted with emissions reduction devices and in 2023-24, the technology resulted in a reduction of more than 4,200 tonnes of CO 2 e emissions and saved nearly $30,000 in fuel costs. Realizing further vent gas emissions reductions through gas conservation As we advance on our roadmap to 35 per cent by 2030, we will focus on vent gas reduction. About 25 per cent of SaskEnergy’s emissions come from venting — the intentional release of gas during maintenance, or a device that vents gas by design. SaskEnergy is focused on a few options for conserving this gas rather than venting or flaring it, which will have a significant positive impact on operational emissions.
INSTRUMENT AIR UPGRADES YIELD INSTANT EMISSIONS REDUCTIONS Traditionally, SaskEnergy’s compressor stations, which help us transport natural gas to homes and businesses across the province, have also used natural gas in the operation of their pneumatic control valves and engine starters. Following an instrument air conversion study in 2022, we are now converting these components at our older compressor stations to run using compressed air rather than natural gas. Because some of these valves continually vent while operating, the ability to have them operate on compressed air results in instant emissions reductions. In 2023-24, we upgraded compressor facilities at Brada and Tantallon to operate using compressed air. It is estimated that these upgrades will result in annual emissions savings of 145 tonnes CO 2 e. All of SaskEnergy’s newer compressor stations are built to use compressed air rather than natural gas.
