Bertrand Piccard, known for his pioneering Solar Impulse balloon and aircraft journeys, is now focusing on hydrogen-powered aviation. Piccard argues that solar-powered planes are impractical for commercial use due to their reliance on heavy batteries, which diminish energy efficiency. His shift towards hydrogen power represents a strategic pivot to overcome the limitations of battery technology and demonstrate the potential of green hydrogen as a clean fuel for aviation.
The Climate Impulse aircraft is distinguished by its novel design, featuring a central pod for pilots and two large liquid-hydrogen tanks. These tanks are positioned on either side of the pod, connected by a single, slender wing. Each tank is equipped with front-mounted propellers and a tail to aid in propulsion and stability. This unique configuration not only supports the aircraft’s aerodynamics but also facilitates the efficient use of hydrogen fuel.
Maintaining the liquid hydrogen at a temperature close to absolute zero, -253°C, throughout the nine-day flight poses a significant technical challenge. To address this, the Climate Impulse team is developing advanced thermal insulation technologies. Raphaël Dinelli, overseeing the aircraft's design and construction, emphasizes that the team is working on revolutionary thermal tanks to ensure the hydrogen remains in its liquid state during the entire journey. This innovation is crucial for the aircraft’s successful operation.
The Climate Impulse project benefits from collaborations with several key partners. Syensqo, a science company specializing in advanced materials, is instrumental in developing the thermal insulation systems required for the aircraft. Syensqo’s CEO, Ilham Kadri, expresses enthusiasm for contributing to this groundbreaking endeavor, highlighting the significance of a non-stop, zero-emission global flight. Additionally, Airbus and Capgemini are providing support in research, development, and design, showcasing a collaborative effort to advance aviation technology.
The Climate Impulse is expected to be completed within two years, following an intensive research and development phase. Testing will commence in 2026, allowing time to refine the aircraft’s systems and address any technical issues. The successful implementation of this project could mark a pivotal moment in the aviation industry, demonstrating that sustainable and efficient long-distance flights are achievable with green hydrogen.
The Climate Impulse project represents a significant step forward in the quest for greener aviation solutions. By showcasing the potential of hydrogen as a viable fuel source, the project aims to challenge prevailing skepticism about decarbonizing aviation. The successful realization of this goal could inspire further innovation in sustainable aviation technologies and pave the way for more environmentally friendly flying options in the future.
This ambitious endeavor by Bertrand Piccard and his team exemplifies the drive to integrate sustainable practices into aviation, potentially transforming the industry’s approach to long-distance air travel and contributing to global climate goals.
