Our Guiding Vision:
a clean & efficient world

This historical flight planned in 2028 aims to be a flagship for climate action, showcasing how efficient solutions can set the world on a sustainable course. The inspiring journey will only be made possible through a shared vision and the power of cooperation, each team member, each man and woman, from the engineers to the meteorologists and the mechanics bringing their own experiences of innovation, pioneering spirit and putting their certitudes into question to power a great trailblazing adventure.

“Efficient solutions will unite people, from citizens and environmental activists to political and business leaders, shifting the narrative from sacrifice and fear to enthusiasm and hope.”

Bertrand Piccard



“More than flying around the world with a hydrogen airplane, Climate Impulse will explore new ways of thinking and acting to promote a better quality of life.”

Bertrand Piccard

“The major technological challenge is to build an aircraft around two liquid hydrogen tanks maintained at -253°C, powering electric motors through fuel cells. The success of our project will pave the way for sustainable and more responsible aviation mobility.”
