Safran OSYRYS Project Targets Hybrid-Electric Aircraft by 2035

Safran Electrical & Power released a video presentation on June 23, 2026, detailing the OSYRYS project, a European consortium aiming to develop electrical and thermal systems for the first hybrid-electric regional aircraft by 2035.

The project, coordinated by Safran as part of the Clean Aviation Joint Undertaking (CAJU), brings together 24 industrial and academic partners from nine countries. According to the company’s press release, the initiative is designed to reinvent energy management systems to achieve a 30 percent reduction in carbon dioxide emissions compared to 2020 state-of-the-art technology.

The Ultra-Efficient Regional Aircraft initiative

OSYRYS (On-board SYstems Relevant for hYbridization of Regional aircraftS) operates as one of four interrelated projects under the Ultra-Efficient Regional Aircraft (UERA) umbrella. The other three projects include HERACLES for aircraft concept development led by ATR, DEMETRA for flight demonstration also led by ATR, and PHARES for hybrid-electric propulsion led by Pratt & Whitney Canada.

The four consortia officially launched during joint meetings in Brussels, Belgium, in January 2026. The collaborative effort is supported by €140 million in funding from Clean Aviation, complemented by €200 million in in-kind contributions from the participating organizations over a five-year period.

Technical objectives and system architecture

The OSYRYS project specifically targets the development of electrical power generation, power distribution, thermal management, and avionics tailored for energy management. These systems are foundational for the transition to hybrid-electric propulsion in the regional aviation sector.

“OSYRYS is a crucial project for the Regional stream in Clean Aviation, providing paramount power distribution and cooling solutions for the hybrid-electric flight demonstration platform and the next Ultra Efficient Regional Aircraft expected to enter into service in the next decade,”

The statement above was provided by Jaime Perez De Diego, Project Officer for the Clean Aviation Joint Undertaking, during the project’s formal launch phase.

AirPro News analysis

We view the 2035 entry-into-service target for a hybrid-electric regional aircraft as ambitious but structurally supported by the parallel development approach of the UERA projects. By separating the airframe, propulsion, flight demonstration, and internal systems into distinct but coordinated workstreams, the European aviation sector is mitigating the integration risks typically associated with clean-sheet hybrid designs. The success of OSYRYS will largely depend on the consortium’s ability to manage the significant weight penalties inherent in advanced thermal cooling and high-voltage power distribution systems.
