Siemens Energy has signed an settlement with Canada-based TC Energy Corporation (TC Energy) to fee what is claimed to be a first-of-its-kind waste heat-to-power pilot set up in Alberta.
The facility will seize waste warmth from a gas-fired turbine working at a pipeline compression station and convert it into emissions-free energy. The electrical energy produced will likely be put again into the grid– leading to estimated greenhouse gasoline reductions of 44,000 tons per yr, equal to taking greater than 9,000 automobiles off the street.

At the center of the power will likely be an modern warmth restoration course of designed by Siemens Energy. The patented expertise, licensed underneath Echogen® Intellectual Property, relies on a complicated Rankine Cycle and makes use of supercritical carbon dioxide (sCO2) because the working fluid to transform waste warmth into energy.
Due to its properties, sCO2 can work together extra straight with the warmth supply than water/steam, eliminating the necessity for a secondary thermal loop, sometimes required in conventional waste warmth restoration techniques.
By deploying sCO2-based waste warmth restoration options, midstream operators can understand better worth than conventional alternate options based mostly on Organic Rankine or steam cycles. Benefits embrace a 25 – 40% smaller footprint than steam-based techniques, a 10% enhance in compressor station effectivity, and the potential to provide clear, emissions-free electrical energy. Moreover, as a result of the working fluid is contained inside a closed-loop system, no boiler operator is required, making the system appropriate for distant operation.
The new facility is predicted to be commissioned towards the top of 2022 and will generate sufficient electrical energy to energy greater than 10,000 properties.
Arja Talakar, senior vice chairman, industrial purposes merchandise for Siemens Energy, mentioned: “We are proud to accomplice with TC Energy to construct this first-of-its-kind facility and stay up for scaling the expertise to different installations within the coming years.”

The pilot mission is supported by CAD $eight million (USD $6.three million) in funding from Emissions Reduction Alberta’s (ERA) Industrial Efficiency Challenge. For greater than 10 years, ERA has been investing the revenues from the carbon value paid by giant remaining emitters to speed up the event and adoption of modern clear expertise options.
“The settlement with Siemens Energy on this initiative exemplifies TC Energy’s lengthy historical past of embracing innovation and modern expertise in its operations,” says Corey Hessen, senior vice-president, and president, energy & storage, TC Energy. “We are dedicated to integrating sustainable vitality options that cut back greenhouse gasoline (GHG) emissions throughout our footprint and stay up for having this operational at considered one of our compressor stations.”
TC Energy is at the moment evaluating different compressor station websites to deploy the expertise, with the potential to generate 300MW of emissions-free energy.
