VANCOUVER, British Columbia, Canada (April 7th, 2025) – Canadian Advanced Air Mobility (CAAM) proudly celebrates a monumental milestone in sustainable aviation, as CAAM National Board member Unither Bioélectronique has completed the world’s first flight demonstration of a piloted hydrogen-powered helicopter. The groundbreaking achievement took place at Roland-Désourdy Airport in Bromont, Québec on March 27, 2025, marking a pivotal moment for sustainable aviation in Canada and beyond.
This milestone is not only the first flight demonstration of a piloted hydrogen-powered helicopter globally—it is also Canada’s first piloted hydrogen-powered flight. The successful three-minute, 16-second flight validated the capabilities of a Proton Exchange Membrane (PEM) hydrogen fuel cell system to support the power demands of vertical take-off and landing (VTOL) flight.
“Our first test flight successfully demonstrated the hover and maneuver capabilities of our innovative hydrogen powertrain,” said Mikaël Cardinal, Vice President, Program Management & Business Development, Organ Delivery Systems for Unither Bioélectronique. “Our next phase of development will focus on integrating a liquid hydrogen storage system, which we believe is an essential technology for enabling our extended-range missions to deliver manufactured organ alternatives to patients in need.”
The historic flight is part of Project Proticity™, a joint initiative between Unither Bioélectronique and Robinson Helicopter Company focused on accelerating zero-emission aviation through the use of hybrid hydrogen-electric propulsion systems. The successful demonstration—performed by test pilot Ric Webb under an experimental flight permit from Transport Canada Civil Aviation (TCCA)—utilized an experimental Robinson R44 Raven II equipped with a dual PEM fuel cell/battery hybrid powertrain, with approximately 90% of the flight’s energy coming from hydrogen fuel cells.
As the national industry association driving sustainable innovation in Canada’s skies, CAAM recognizes this as a transformative moment for the sector.
“This historic achievement proves that clean aviation isn’t a distant dream—it’s a present-day reality taking flight right here in Canada,” said JR Hammond, Executive Director of CAAM. “Unither’s success is a shining example of the innovation happening across our ecosystem and demonstrates how Canadian leadership is shaping the global future of zero-emission air mobility.”
Unither’s success reaffirms Canada’s growing leadership in clean aviation, underlining the nation’s potential to be a global testbed for next-generation aerospace technologies. Unither’s leadership, combined with Robinson’s aviation expertise, sets the stage for transformative applications in emergency response, healthcare, and logistics.
