A hydrogen plane that aims to circle the globe non-stop and with zero emissions is carrying a mission, as well as hope, about sustainability to the youth.

The Swiss explorer Bertrand Piccard, who completed the first round-the-world solar-powered flight and was the first to complete a non-stop balloon flight around the globe, said his latest hydrogen venture is now nearing completion and the first test flights are scheduled for early 2027.

The project, developed through the Solar Impulse Foundation, carries two ambitions. The first is to demonstrate that hydrogen can power a full circumnavigation of the Earth without a single stopover or gram of carbon emissions.

The second is a message of hope for the future. One where flight is enjoyed without causing damage to the planet.

"We want to show young people that there are solutions, that there is a future — but we must now develop the pioneer spirit," Piccard told Euronews Next.
