H55, announced the delivery of certification-grade propulsion battery modules to Pratt & Whitney Canada in support of the RTX Hybrid-Electri
H55 has achieved production-conforming energy storage systems for hybrid-electric aircraft, marking a significant step toward the commercialization of cleaner, safer, and more efficient aviation technologies.
“They require certification-grade safety architecture, industrialized manufacturing, operational reliability and scalable systems integration. Delivering production-conforming modules into the RTX Hybrid-Electric Flight Demonstrator validates H55’s ability to meet those requirements at an industrial scale and marks an important step in bringing our certification-grade energy storage technologies to a broader range of commercial aerospace applications. This achievement provides a strong foundation for what comes next across hybrid-electric aviation, defence, UAVs and next-generation aerospace platforms.” said, Sebastien Aymon-Demont, H55 Co-Founder and CTO.
