SaskEnergy pipeline subsidiary TransGas, together with partner companies Found Energy and Innovative Steam Technologies (IST) will use an innovative technology designed to capture the waste heat of compressor station engines and convert it to useable electricity. If successful, the corporation could be producing more renewable electricity than it consumes by 2015, thanks to this new green technology. The project will also help develop Waste Heat Recovery technology for applications with other energy industry markets in Western Canada.
TransGas uses compressors to move natural gas through its 14,000 kilometres of high pressure transmission pipeline across Saskatchewan, as well as to inject gas into its 27 underground storage caverns and two storage fields.
"SaskEnergy and TransGas have set a goal to become net zero in electricity consumption by 2015 and Waste Heat Recovery will be one of the key factors in pursuing this goal," said Minister Responsible for SaskEnergy Dustin Duncan. "Recovering waste heat from compressor engines will reduce the corporation's carbon footprint and our province's reliance on traditional, electrical generation sources. Through this project, SaskEnergy is supporting Saskatchewan's 'Go Green' initiative by investing in an environmental solution to an every day business process."
The $5.7M Waste Heat Recovery project at TransGas' Rosetown and Coleville Compressor Stations will capture heat normally vented to the atmosphere through the compressor engines' exhaust, and converts it to electricity utilizing a process called the Organic Rankine Cycle. The electricity will then be sold back to the SaskPower grid.
