Hydrogen and hydrogen-electric propulsion represent a promising path towards achieving zero emission aviation. When produced from clean electricity, hydrogen has no CO2 emissions over its life cycle. Hydrogen can be combusted through modified gas-turbine engines or converted into electrical power that complements the gas turbine via fuel cells. The aviation industry and governments jointly foster disruptive innovation combined with sustainability. 
 

The Vienna Aviation days are organized through the Horizon Europe project exFan (101138184). The aim of this congress is to establish a platform to enable an exchange of green aviation topics for aviation research projects and build a connection between the different projects, programmes and policy makers. The topics of the projects contribute to future Hydrogen/Hybrid electric aircraft propulsion systems. 
 

At the event, the participating projects will present their activities towards hydrogen propulsion. The audience can gain an insight into the tasks and challenges of the individual projects. This will serve as a basis for discussion and subsequent one-to-one meetings and pave the way for possible cross-project collaboration or to create ideas and cooperation for new projects. 
 

Participation at the Vienna Aviation Days will be free of charge. 
 

Preliminary Agenda 
 

Day 1: 13:00 - 17:30
Welcome address
Block 1 Policy, strategies

First hydrogen powered aircraft are expected to reach market readiness by 2035. Potential deployment will focus on regional and single aisle aircraft. European and national policies foster and support the maturation of this technology. This block will cover the strategies and challenges presented by the public sector.

Panel discussion

Block 2 Challenges & Opportunities

The successful transition towards hydrogen propulsion faces different challenges and opportunities. Those include future aircraft emissions such as non-CO2, contrails, or noise as well as ground infrastructure.

Panel discussion

18:30 Dinner at TUtheSky
Day 2: 9:00 - 13:30
Block 3 Hydrogen Combustion & Hydrogen- electric propulsion systems

Different projects will present their contribution for the path towards hydrogen propulsion and their technological challenges that need to be overcome in order to reach its full potential.

Panel discussion

Block 4 Architecture, On Board Storage, Modelling

Liquid Hydrogen with its low temperature of -253°C creates new challenges in the airplane. Those include tank, on board storage and fuel distribution systems as well as refuelling. This block will present different innovative solutions.

Panel discussion

End of the event and Farewell : 13:45 (Closing remarks)
