Pratt & Whitney to Demonstrate Hydrogen-Fueled Technology on PW127XT Engine Under INSAT Program


Pratt & Whitney Canada, a subsidiary of RTX, is set to advance sustainable aviation through the demonstration of hydrogen combustion technology on its PW127XT regional turboprop engine. This initiative is part of the Hydrogen Advanced Design Engine Study (HyADES), supported by Canada’s Initiative for Sustainable Aviation Technology (INSAT).

The project aims to test hydrogen fuel nozzles and combustor rigs in the first phase, with future phases targeting full engine ground testing. The PW127XT engine, designed with superior fuel efficiency and reduced maintenance costs, will be adapted to operate with low-carbon alternative fuels, showcasing its versatility and efficiency.


Pratt & Whitney’s collaboration with Next Hydrogen Solutions Inc. will also focus on developing high-efficiency, low-cost electrolyzers essential for establishing hydrogen production infrastructure. This partnership underscores the critical role of green hydrogen in reducing aviation CO2 emissions, either as a direct fuel for combustion or as feedstock for sustainable aviation fuel (SAF).


In addition to HyADES, Pratt & Whitney Canada is involved in the Turbine Engine Advanced Materials for Efficiency (TEAME) project, which explores advanced materials for gas turbine engines to improve thermal efficiency and reduce emissions. This project, also supported by INSAT, highlights Pratt & Whitney’s commitment to pioneering technologies that enhance aviation sustainability.


Edward Hoskin, Vice President of Engineering at Pratt & Whitney Canada, emphasized the importance of these initiatives: “This collaborative project with INSAT enables us to develop key technologies for future hydrogen-powered aircraft and complements our wider efforts to advance aviation sustainability through a range of pathways, including continued improvements to engine efficiency, hybrid-electric propulsion, and compatibility with sustainable aviation fuel (SAF)”.


Pratt & Whitney’s efforts under the INSAT program represent a significant step towards a greener future for aviation, leveraging innovative technologies to reduce the industry’s carbon footprint and promote sustainable practices.
