Clean Aviation Call 2025

The Clean Aviation Joint Undertaking (CAJU) is a successful public-private partnership between the European Commission and the European aviation industry that aims to achieve a sustainable and climate-neutral transformation of aviation.

The third call for project proposals is expected to be published in February 2025 and will be centered around the following areas and topics:

Aircraft Concept Integration & Impact Assessment (ACI&I): €15 million
Ultra-efficient Short-Medium Range (SMR) aircraft architectures: €205 million
- Ground Test Demonstration and Preparation of Flight Test of an Ultra High Bypass Ratio Ducted Geared Turbofan Engine
- Flight Test Demonstration of an Unducted Engine Architecture
- Ground Test Demonstration up to TRL5 of On-Board NPE Systems Architecture
Ultra-efficient Regional (REG) aircraft architectures: €145 million.
- Demonstration of a Hybrid-Electric Propulsion System for Regional aircraft, including Pylon and Nacelle Integration and modification
- Demonstration of On-board Systems relevant for hybridization of Regional aircraft
- Flight Test Demonstration of Hybrid-Electric Propulsion for Regional aircraft

Clean Aviation is also introducing a new initiative to play a crucial role in advancing disruptive technologies: the Fast Track Areas (FTAs) for a total funding volume of €15 million. These are designed to de-risk alternative or complementary technical solutions, enabling a faster implementation process and enlarging the breadth of competencies. The focus will be on the following topics:

Design and Integration of a High-Performance Battery System on a Hybrid-Electric Regional aircraft
Crashworthiness of fuselage integrated LH2 storage solutions
Advanced Concepts for Reliable Power Electronics Conversion and Distribution in Aviation

Priority will be given to projects that can rapidly advance impactful technologies to the development phase and are closely connected to the SMR and REG projects, encouraging the participation of universities, research centres, and SMEs.
