Pratt & Whitney and H55 team up to develop sustainable propulsion technology

The participation of H55 in the hybrid-electric demonstrator program follows P&WC's July 2021 announced plans of investing $163 CAD million (CHF 124 m), with the support of the governments of Quebec and Canada, towards developing this 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.

Ground testing of the propulsion technology will already start this year, with a planned flight demonstration in 2024. 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.

“Our goal has always been to target regional commuter transportation and with P&WC, there is a perfect fit whereby our core technologies complement each other,” said André Borschberg, H55’s Co-founder and Executive Chairman. “Both companies share the same vision as to how hybrid-electric propulsion can offer a range of environmental and economic benefits. Having been selected by P&WC is an important validation that our experience is valued by a reputable industry player. We are excited to be working in Quebec with P&WC and several other industry and research collaborators in bringing our battery pack to the hybrid-electric demonstrator program”.

“We’re delighted to draw from H55’s proven technology in the field of aircraft battery systems,” said Jean Thomassin, executive director new products and services, Pratt & Whitney Canada. “Hybrid-electric technology holds significant potential to boost the efficiency of next generation aircraft propulsion systems, allowing us to set new standards for sustainability for regional and commuter aircraft.”
