Deadline: 19-May-2026
The hybrid-electric propulsion funding initiative under Horizon Europe provides €329.5 million to support ground-based demonstrations of ultra-efficient SMR aircraft technologies. The call focuses on advancing hybrid-electric propulsion systems to reduce emissions and enable next-generation sustainable aviation.
Overview of the Programme
This large-scale funding call supports the development and validation of hybrid-electric propulsion systems for Small and Medium Range (SMR) aircraft.
It emphasizes real-world, ground-based demonstrations to test performance, integration, and environmental impact before commercial deployment.
Core Objectives
The initiative aims to:
- Advance hybrid-electric propulsion technologies
- Reduce aviation-related carbon emissions
- Support sustainable aircraft innovation
- Enable future commercialization of green aviation solutions
- Align research with long-term industry deployment goals
Key Focus Areas
Projects should address:
- Hybrid-electric propulsion system development
- Integration into ducted and unducted engine architectures
- Ground-based demonstration in realistic environments
- Subsystem validation and performance testing
- Roadmapping toward higher technology readiness
Technical Targets
Projects are expected to:
- Achieve Technology Readiness Level 5 (TRL5)
- Demonstrate at least 5% CO₂ reduction at aircraft level
- Develop a roadmap toward TRL6 by 2030
- Support entry into service by 2035
Funding Details
- Total budget: €329,500,000
- Funding supports large-scale, high-impact R&D projects
- Focus on demonstration and validation rather than early-stage research
