TRANSCEND (Technology Review of Alternative and Novel Sources of Clean Energy with Next-generation Drivetrains) is initiated by the research centre NLR in response to the Clean Sky 2 CfP9 under the topic “Alternative energy sources and novel propulsion technology”.

The objective of TRANSCEND is to shape the future of green aviation propulsion in 2050, complementing the development plan of Clean Sky 2. TRANSCEND evaluates the environmental impact at aircraft and air transport levels of alternative energy sources and novel propulsion technology for aircraft with entry-into-service before 2050.

In addition, TRANSCEND provides a TRL-based technology roadmap for promising propulsion technologies and a roadmap regarding economic viability and availability for the associated alternative energy sources. Support for TRANSCEND results is generated from the start through the Advisory Board, which consists of representatives of stakeholders for exploitation (e.g., KLM, EASA).

TRANSCEND will base its results on a thorough literature study, complemented with interactions with numerous experts, including three expert workshops. We will evaluate alternative energy sources and novel propulsion technologies, their integration into aircraft, and their diffusion into seat classes into the air transport system. We will generate support of stakeholders and experts through dedicated communication and dissemination.

NLR’s strong track record in propulsion technology and, partly in alternative energy sources, NLR’s extensive experience in Clean Sky and European innovation (RIAs, IAs) and policy support (in CSAs and nationally), and the broad network of NLR motivates this application. Delft University of Technology (TUD) as TRANSCEND partner adds its expertise, experience, and network in alternative energy sources.

The TRANSCEND total grant request to the JU is €348,335. The project will be conducted in 30 months in close alignment with the topic leader and other stakeholders.
