CNX converting Natural Gas Compressor waste heat to carbon-reducing CHP for operations

Natural gas producer CNX Resources has collaborated with Houston-based energy firm ICE Thermal Harvesting on a pilot project to produce 100-percent clean energy for CNX’s operations.

Under the first phase of the project, which is being carried out at CNX’s Dry Ridge compressor station in West Virginia, engine exhaust heat will be captured and converted to power ICE’s patented heat-to-power systems.

Once fully implemented, the technology will generate around 500 kW of sustainable electricity and reduce 1,325 metric tons of CO2 annually during the first phase. As the project expands to later phases, it is expected to reduce CO2 emissions by nearly 4,000 metric tons per year.

“Capturing waste heat from compressor stations enables CNX to generate locally-sourced, zero-emission power for our operations and further reduce overall emissions,” CNX President of New Technologies Ravi Srivastava said. “Our initial pilot project with ICE makes good business and environmental sense.”

According to CNX, the project aligns with its “Appalachia First” vision of identifying and deploying innovative technologies that drive operational efficiencies, environmental progress, and commercial excellence.

Building upon the success of the initial application at Dry Ridge, additional systems will be installed at the station during Phases Two and Three to harvest heat during the compression process.

“ICE Thermal Harvesting sees opportunity where others see waste,” Carrie Murtland, Co-founder of ICE stated. “Working alongside innovators like CNX, we continue to demonstrate that energy producers can cost-effectively address on-site power needs while reducing carbon emissions.”

CNX Resources is headquartered in Pittsburgh, Pennsylvania with operations centered in the major shale formations of the Appalachian Basin, such as the Marcellus and Utica shale plays. The company produced 590 billion cubic feet equivalent of natural gas in 2021 and has proved reserves of approximately 10 trillion CFE, according to reports.

Based in Houston, Texas, ICE Thermal Harvesting focuses on supplying zero-emission power in various regions around the world.
