Josef Kallo is a true sustainable aviation pioneer. He was already working on hydrogen-powered aircraft back in 2013, when few outside a small circle had heard about sustainable aviation or alternative propulsion technologies.

Fast forward to 2021 and H2FLY, the company he has been leading for over a decade, made headlines after being acquired by Joby Aviation, one of the forerunners in the advanced air mobility race.

During all this time, H2FLY has been steadily and quietly making strides in the field of hydrogen propulsion and, in September 2023, it made history be being the first to fly an aircraft on liquid hydrogen, a technology that poses some interesting technology challenges.

What is H2FLY currently working on? What is the future of hydrogen-powered aviation? What role is H2FLY going to play in also powering the eVTOL revolution?

Tune in for an in-depth conversation with one of the world’s leading experts in hydrogen aviation, Josef Kallo!
