H55 Delivers Certification-Grade Propulsion Battery Modules to Pratt & Whitney Canada, Supporting Demonstration of Hybrid-Electric Aircraft Technology
Production-conforming systems manufactured in a regulator-approved facility mark H55’s transition from technology development to commercialization of certification-grade energy storage solutions for hybrid-electric aviation.
H55 today announced the delivery of certification-grade propulsion battery modules to Pratt & Whitney Canada in support of the RTX Hybrid-Electric Flight Demonstrator — a milestone that further validates H55’s transition from technology development to industrial-scale execution and represents an important step in the commercialization of the company’s certification-grade energy storage technologies for hybrid-electric aerospace applications. Pratt & Whitney is an RTX business.
