Climate Impulse Team Showcases Hydrogen’s Potential as Alternative Aviation Fuel
The aviation industry is actively seeking ways to reduce its carbon footprint, and hydrogen fuel is emerging as a promising alternative to power air travel. To demonstrate hydrogen’s potential, a team based in Les Sables-d’Olonne, France, is developing a hydrogen-powered aircraft called Climate Impulse, with the ambitious goal of being the first to circumnavigate the globe without stopping.
Swiss Explorer Bertrand Piccard Leads the Climate Impulse Project
Bertrand Piccard, a Swiss explorer who previously co-piloted the Solar Impulse aircraft that flew around the world using solar power between 2015 and 2016, is spearheading the Climate Impulse project. Piccard believes this endeavor could be a significant catalyst for the aviation industry’s transition to cleaner energy sources.
“A lot of people say that you cannot decarbonize aviation. Climate Impulse, that’s my call against defeatism, against skepticism, against all the people who say there are no solutions,” Piccard told CNBC Tech: The Edge. “There are a lot of solutions, but hope will come only if we take action.”
Challenges of Hydrogen-Powered Aviation
Transitioning to hydrogen-powered aviation is not a simple matter of changing the fuel in existing planes. One of the primary challenges is the need to maintain liquid hydrogen at temperatures close to absolute zero, which creates unique design hurdles. Despite these obstacles, the Climate Impulse team chose hydrogen fuel for their project.
“If you want to be fully decarbonized, you can go on solar … but it’s not practical for commercial aviation,” Piccard explained. “If you have bigger planes, you need bigger batteries, and a part of your energy will be wasted by carrying the heavy batteries. So that’s the moment where it’s more efficient to go on hydrogen.”
Climate Impulse’s Timeline and Goals
The Climate Impulse team aims to attempt its round-the-world flight in 2028, with testing of the hydrogen-powered aircraft set to begin in 2026. The project’s success could help showcase the viability of hydrogen as an alternative fuel for the aviation industry and inspire further investment and research in this area.
As the race to decarbonize air travel continues, initiatives like Climate Impulse are crucial in demonstrating the potential of alternative fuels and propulsion systems. While many challenges remain in terms of design, infrastructure, and industry adoption, projects like these offer hope for a more sustainable future in aviation.
