RTX's Pratt & Whitney to demonstrate hydrogen-fueled turboprop technology
under Canadian INSAT program







First phase of HyADES project will include tests on PW127XT engine fuel
nozzle and combustor rig

MONTREAL, Nov. 6, 2024 /PRNewswire/ -- Pratt & Whitney Canada will demonstrate
hydrogen combustion technology on a PW127XT regional turboprop engine as part
of a project supported by Canada's Initiative for Sustainable Aviation
Technology (INSAT). The project, named Hydrogen Advanced Design Engine Study
(HyADES), will be in collaboration with Next Hydrogen Solutions Inc., which
will develop high-efficiency, low-cost electrolyzers needed for establishing
hydrogen production infrastructure. Pratt & Whitney is an RTX (NYSE: RTX)
business.

"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)," said Edward Hoskin, vice
president, Engineering, Pratt & Whitney Canada. "While regional aviation
represents one of the most promising use cases for hydrogen, the project will
also demonstrate the versality of adapting the proven, highly efficient
PW127XT turboprop engine to operate with low carbon alternative fuels and
continues our legacy of technology leadership in this segment."

Funding for the first phase of the project will include fuel nozzle and
combustor rig testing using hydrogen fuel, while future phases will target
full engine ground testing. The PW127XT engine is the most advanced member of
Pratt & Whitney Canada's PW100 engine series, which has powered regional
turboprop aircraft for forty years and accumulated more than 220 million
flight hours. Launched in 2021, the PW127XT engine offers over 3% better fuel
efficiency, 40% improved time on wing, and 20% reduced maintenance costs.

"We are thrilled to collaborate with INSAT and Pratt & Whitney Canada on this
project," said Raveel Afzaal, president and CEO of Next Hydrogen Solutions
Inc. "The ability to produce green hydrogen at scale will be a critical
enabler for reducing aviation CO2 emissions, whether using hydrogen as a
direct fuel for combustion or as feedstock for SAF."

As part of a second INSAT-supported project, Turbine Engine Advanced Materials
for Efficiency (TEAME), Pratt & Whitney Canada will work with Derivation
Research Laboratory (DRL) to explore advanced materials for hot section
components of gas turbine engines, which will help to improve thermal
efficiency and reduce fuel consumption and emissions. Pratt & Whitney Canada
will lead the overall project providing both technical input and project
management, while DRL will provide world-class materials testing capability
for a wide variety of critical material properties.
