Category Call for proposal

The Clean Aviation Joint Undertaking is the European Union’s leading research and innovation programme for transforming aviation towards a sustainable and climate neutral future.

It aims to develop disruptive new aircraft technologies to support the European Green Deal, and climate neutrality by 2050. These technologies will deliver net greenhouse gas (GHG) reductions of no less than 30%, compared to 2020 state-of-the-art.

The aircraft developed will enable net CO2 reductions of up to 90% when combined with the effect of sustainable ‘drop-in’ fuels, or zero CO2 emissions in flight when using hydrogen as energy source.

With a budget of € 735.72 million, 14 new topics of this programme opened on 12 April 2022 for this first Call for Proposals of the JU.

Eligibility: Clean Hydrogen JU is an institutionalised partnership that does not require national co-funding and legal entities based in Switzerland are eligible and the (non-) association determines the mode of financing. As Switzerland is now considered a non-associated third country, participants will receive funding via the State Secretariat for Education, Research and Innovation (SERI).
