In this podcast, Ralph discusses the company’s rapid evolution toward commercial hydrogen-electric aviation.

Since taking leadership, he has focused on accelerating development, scaling operations, and strengthening partnerships with aircraft manufacturers. He highlights key learnings from demonstrator programs like the HY4 and collaborations with Joby Aviation, which informed more ambitious technology roadmaps.

A major theme is the transition to megawatt-class fuel cell systems, where system architecture, integration, and efficiency are critical challenges. Ralph emphasizes that early adoption will likely occur in small, electrified aircraft, where hydrogen extends range beyond battery limits. He also underscores the importance of early OEM collaboration, certification alignment, and infrastructure development, including hydrogen production and refueling.

Looking ahead, Ralph shares more details about certification progress, power density improvements, and supportive policy as key to achieving scalable, zero-emission aviation by 2030.
