H55 has been selected by Harbour air to provide the energy storage system for the first commercial electric version of the Beaver commuter seaplane. H55 lightweight battery modules will be part of an electric propulsion system whereby the US based magniX will be providing the motor. Once the 1^st prototype is certified, Harbour Air plans to first retrofit their entire fleet and then offer the possibility to other Beaver owners the possibility to convert their aircraft to electric.

Harbour Air, North America's largest seaplane airline —and the first to be fully carbon-neutral offers flight services around the island of Vancouver, BC, Canada. With short flights, no longer than 30-45 min, their airline service is the perfect application for electric aircrafts and becoming the first airline operating electric airplanes.

Pratt & Whitney Canada (P&WC) has selected H55 to provide the battery pack for the company’s regional hybrid-electric flight demonstrator program. The program is supported by the Government of Quebec and Canada towards developing sustainable propulsion technology. Collins Aerospace and De Havilland Aircraft of Canada are key technology collaborators in the demonstrator project. The National Research Council Canada (NRC) and the Innovative Vehicle Institute (IVI) are also supporting the development of some of the component designs and electrical control systems for the project. A 30% improvement in fuel efficiency and commensurate reduction in CO2 emissions is targeted, compared to today’s most advanced turboprop engines for regional aircraft. Ground testing of the propulsion technology will already start this year, with a planned flight demonstration in 2024.

H55 is partnering with CAE and Piper Aircraft to develop a conversion kit for in-service Piper Archer ® (PA-28-181) aircraft and bring an electric variant of the aircraft to market as a Supplemental Type Certificate (STC). H55 has committed to designing and manufacturing the aircraft battery system to support CAE in the conversion of two-thirds of its Piper Archer ® training fleet with electric propulsion and make the conversion kit available to all operators of the aircraft type.

CAE is a high technology company and leading aviation training organization. The company offers training and operational support solutions in civil aviation, defense and security, and healthcare. CAE is also the biggest flight school operating a fleet of Piper Archer.
