H2-Sling

The dream of 100% emission free hydrogen flight

Our Mission

to prove with the H2-Sling that hydrogen is a feasible and reasonable alternative to conventional fuel in aviation.

Conceptual study

While developing the s-Sling we had already started working on creating a proof of concept. In the same year, 2022, we successfully generated electricity with a fuel cell for the first time - an important milestone, marking the beginning of developing and sampling a 100kW hydrogen powertrain.

Our approach

We focus on the development of the system as a whole rather than on individual components. We take existing, proved components and rearrange them in a way that hasn't been done by anybody before. Not only the system design but also the structural integration into our carrier plane as well as safety are in the centre of our attention.

Crossing the Alps

Mit dem geplanten Erstflug im Frühling 2026 streben wir an, das erste wasserstoffbetriebene Flugzeug der Schweiz – und sogar das weltweit erste von Studierenden gebaute Wasserstoffflugzeug – zu werden. Doch unser Ziel geht über den reinen Machbarkeitsnachweis hinaus: Mit einem späteren Flug über die Alpen wollen wir auch die Praxistauglichkeit und Leistungsfähigkeit unseres Antriebsstrangs unter Beweis stellen!

H2-Sling

The H2Sling is powered by a 100kW fuel cell system. Using gaseous hydrogen together with oxygen from the air it generates electricity and heat. The only byproduct created is pure water - completely emission free. Due to the high energy density of hydrogen the H₂-Sling provides a significant range, creating new dimensions in terms of sustainable mobility.
