ENABLEH2 has provided thought leadership through revitalising enthusiasm in LH2 research for civil aviation to exploit the fuel’s unique environmental benefits. This was achieved by maturing key technologies to achieve zero mission-level CO2 and ultra-low NOx emissions, demonstrating safety and long-term sustainability that will not be possible with other fuels i.e. Jet A-1, LNG or Sustainable Aviation Fuels (SAF).

Dr. Bobby Sethi, member of the technical panel for the „Freedom Flight Prize“

Dr. Bobby Sethi, Coordinator of the H2020 ENABLEH2 project has been invited to serve on the technical panel for the „Freedom Flight Prize“, which will be awarded to the first successful zero-carbon transatlantic flight for a passenger aircraft. The panel consists of five members who will decide the final winner and provide updates throughout the competition on breakthroughs and technological updates.

ENABLE2 The Project

The project

‘ENABLing cryogEnic Hydrogen based CO2 free air transport – ‘ENABLEH2’ is a Horizon 2020 project, funded by the European Commission under the grant agreement no 769241. ENABLEH2 is a three-year project started in September 2018.




ENABLE2 The Technologies

The Technologies

ENABLEH2 is providing thought leadership through revitalising enthusiasm in LH2 research for civil aviation by maturing key technologies to achieve zero mission-level CO2 and ultra-low NOx emissions, with long term safety and sustainability.

Project Progress

A summary of the key achievements in the first 18 months of ENABLEH2 is available here.






ENABLE2 Consortium


The consortium has a diverse and balanced representation from leading European Universities (Cranfield University, Chalmers University and London Southbank University), aero-engine OEM industry partners (SAFRAN and GKN Aerospace), the (by passenger traffic) largest airport in Europe (Heathrow), the European Fuel Cell and Hydrogen Association and the European leader in collaboration engineering and project management (ARTTIC).

ENABLEH2 Key Target

The overall aim of the ENABLEH2 project is to demonstrate that LH2 offers a viable route for long-term sustainability of civil aviation with unrivalled environmental benefits, over the complete life cycle, relative to carbon-based fuels.

Project benefit 1

Develop technologies which will make a substantial contribution to meeting (and even exceeding) many of the very ambitious environmental targets for civil aviation.

Project benefit 2

Complement research in other sectors thereby supporting transition towards a hydrogen economy and develop technologies and safety practices that may be adopted across a number of sectors (e.g. energy).

Project benefit 3

Revitalise enthusiasm in LH2 for civil aviation by:
• engaging with key aviation stakeholders
• demonstrating that the environmental case for LH2 will also be supported by an economic case for LH2 in the long term
• alleviating public perception safety concerns about LH2 for civil aviation
• dissemination in public workshops and conferences, publication of papers and an efficient communication strategy.

There are challenges in using liquid hydrogen for civil aviation but we are hopeful of addressing them within the scope of the project. We want to show that hydrogen can be not only beneficial environmentally but can be employed safely and affordably in the medium to long-term.
