Korea Western Power Company, Tallgrass, and PSM to Collaborate on Utility Scale Decarbonization

Accelerating the Clean Energy Transition for Gas Turbine Power Generation

TAEAN-GUN, CHUNGCHEONGNAM-DO, South Korea & LEAWOOD, Kan. & JUPITER, Fla.–(BUSINESS WIRE)-­KOWEPO, Tallgrass, and Power Systems Mfg, LLC (PSM) today announced their agreement to collaborate on key infrastructure investments for the conversion of natural gas-fired power generation to clean hydrogen fuel use in the United States. Focused on investment in utility-scale hydrogen-to-power projects in the United States, the parties will leverage KOWEPO’s global experience in power generation and asset management, Tallgrass’ experience throughout the U.S. in traditional and decarbonized energy infrastructure, supply and logistics, and PSM’s innovative, fuel-flexible FlameSheet™ gas turbine combustion system retrofit solution, part of their global multi-OEM aftermarket services portfolio.

Se-moon Lee, Head of New Overseas Business Department from KOWEPO, said, “We are delighted to cooperate with Tallgrass and PSM, which have expertise in clean hydrogen co-fired power generation projects. This cooperation is expected to greatly contribute to the ‘2050 carbon neutral’ vision of KOWEPO through sustainable energy transition. KOWEPO is developing a hydrogen co-firing project in The Netherlands and a green ammonia production project in UAE. By partnering with Tallgrass and PSM, we have a new opportunity to enter the US power industry and will help expand the foundation to meet future decarbonized energy needs in the US.”

“We are pleased to work with KOWEPO and PSM on another important step to spur investment in decarbonizing U.S. power generation through clean hydrogen,” said Blake Hotzel, Tallgrass’ Vice President of Business Development. “This initiative, coupled with our investments in the Escalante H2 project in New Mexico and the Trailblazer CO2 conversion project, reflects our expanding commitment to decarbonization broadly across the energy industry. By teaming with KOWEPO and PSM, we can advance investment in the type of affordable, reliable and dispatchable decarbonized energy that will be critical to meeting future energy needs in the US.”

‘Today’s installed fleet of gas turbines play a fundamental role in the US grid infrastructure by offering reliable, flexible and responsive capacity, complementing the growing portfolio of intermittent, zero emission renewable power,” said Jeff Benoit, PSM’s Vice President for Clean Energy Solutions. “Our FlameSheet™ combustor retrofit, first installed in OEM gas turbines in 2015, will ultimately enable operational flexibility with 0-100% clean hydrogen and single digit NOx emissions, allowing these ‘future-proof’ assets to fully participate in our country’s clean energy transition. By partnering with Tallgrass and KOWEPO, we will pull this vision forward.”
