Siemens Energy has signed an agreement with TC Energy to commission a novel waste heat-to-power pilot installation in Alberta, Canada. The facility will capture waste heat from a gas-fired turbine operating at a pipeline compression station and convert it into emissions-free power. The electricity produced will be put back into the grid– resulting in estimated greenhouse gas reductions of 44,000 tons per year, equivalent to taking more than 9,000 vehicles off the road.

As part of the agreement with TC Energy, Siemens Energy will build, own, and operate the facility, with the option for ownership to be transferred back to TC Energy at a later date.

An innovative heat recovery process designed by Siemens Energy will be at the heart of this recovery process. The patented technology, licensed under Echogen® Intellectual Property, is based on an advanced Rankine Cycle and uses supercritical carbon dioxide (sCO2) as the working fluid to convert waste heat into power. Because of its properties, sCO2 can interact more directly with the heat source than water/steam, eliminating the need for a secondary thermal loop, typically required in traditional waste heat recovery systems.

“This pilot project is a testament not only to our extensive capabilities but also to Siemens Energy’s broader commitment to bring new technologies to market that can support decarbonization in the oil and gas industry,” said Arja Talakar, Senior Vice President, Industrial Applications Products for Siemens Energy. “We are proud to partner with TC Energy to build this first-of-its-kind facility and look forward to scaling the technology to other installations in the coming years.”  TC Energy is currently evaluating other compressor station sites to deploy the technology, with the potential to generate 300 megawatts of emissions-free power.

$8 million in funding from Emissions Reduction Alberta’s (ERA) Industrial Efficiency Challenge is being earmarked to support this project. For more than 10 years, ERA has been investing the revenues from the carbon price paid by large final emitters to accelerate the development and adoption of innovative clean technology solutions. Since ERA was established in 2009, they have committed $616 million toward 186 projects worth $4.55 billion that are helping to reduce GHGs, create competitive industries, and are leading to new business opportunities in Alberta. These projects are estimated to deliver cumulative reductions of 35 million tonnes of COe by 2030.
