Preparing UK airports for zero emission aircraft

The UK Government is investing in the infrastructure upgrades required at UK airports to move to battery and hydrogen-powered aircraft.

As part of this we are delivering the Zero Emission Flight Infrastructure (ZEFI) programme in collaboration with the Department for Transport.

ZEFI brings together government, industry, and academia to better understand the infrastructure changes required at airports and airfields to prepare for hydrogen-powered and battery electric aircraft.

The ZEFI programme incorporates three key streams:

  • A detailed study which is investigating the requirements for introducing zero emission aircraft into airports. The study is taking input from a wide range of sources and stakeholders to develop use cases for different types of airfield and airports, an operational concept for the use of the new fuels and current aviation fuels alongside each other, plus the development of technology and standards roadmaps for hydrogen- and battery-related infrastructure. The detailed study is underway, and findings will be made available on our website at the end of the project.
  • A Transport Research and Innovation Grant: Zero Emission Flight (TRIG:ZEF) competition, supporting UK research and development related to zero emission flight infrastructure. At least 12 projects will receive up to £50,000 of funding and will be supported by Connected Places Catapult throughout their duration. The TRIG:ZEF programme was launched in June 2021 and the winners have been announced.
  • Demonstrations to showcase UK technology and innovation, and to build our understanding of the use of hydrogen and batteries in airside environments.

We are always happy to hear from interested parties, so if you have questions or ideas related to the ZEFI programme or how you can help us, just email us at

ZEFI Demonstrations

Connected Places Catapult is proud to announce that four organisations will undertake demonstration activities to support our Zero Emission Flight Infrastructure project. These activities will showcase the UK’s technology and innovation while building our understanding of the use of hydrogen and batteries in airside environments.

The demonstrations of the use of hydrogen and greater electrification in airside environments will inform our research on adaptions needed by airports and airfields which will be published and disseminated in the coming months.

Connected Places Catapult identified the following organisations as key leaders and innovators in rendering these demonstrations possible:

ZeroAvia project demonstration
NEBOAir/Nuncats demonstration
