Pratt & Whitney Canada, a division of RTX (NYSE: RTX), is set to pioneer hydrogen combustion technology through its Hydrogen Advanced Design Engine Study (HyADES). This initiative, supported by Canada’s Initiative for Sustainable Aviation Technology (INSAT), focuses on adapting the PW127XT regional turboprop engine for hydrogen use. In collaboration with Next Hydrogen Solutions Inc., the project aims to establish efficient hydrogen production infrastructure via cost-effective electrolyzers, accelerating the aviation sector’s shift to sustainable energy sources.
Edward Hoskin, Vice President of Engineering at Pratt & Whitney Canada, highlighted the transformative potential of the project. He emphasized that hydrogen-powered regional aviation could significantly reduce carbon emissions and enhance sustainability. This effort complements ongoing advancements in hybrid-electric propulsion, sustainable aviation fuel (SAF) compatibility, and engine efficiency improvements. The PW127XT engine, launched in 2021, already boasts a 3% fuel efficiency increase, 40% longer time on wing, and 20% lower maintenance costs compared to its predecessors.
The initial phase of HyADES will involve hydrogen fuel testing in fuel nozzles and combustor rigs, with future stages planned for full engine ground testing. Additionally, through another INSAT-supported project, TEAME (Turbine Engine Advanced Materials for Efficiency), Pratt & Whitney Canada and Derivation Research Laboratory (DRL) will develop advanced materials to enhance gas turbine engine efficiency. These initiatives solidify Pratt & Whitney Canada’s leadership in sustainable aviation innovation, leveraging decades of expertise to drive the next era of flight.
