The government will invest up to £43 million for green aviation research, aimed at cutting emissions while supporting growth and airport expansion plans at Heathrow, Gatwick and Luton.

The funding will be opened to businesses, universities and researchers, with competitions launching from February, and will focus on technologies such as zero-emission aircraft, hydrogen fuels and cleaner aviation systems as part of the UK’s net zero 2050 ambition.

It could also support trials to reduce warming contrails and help the Civil Aviation Authority develop regulation needed for wider hydrogen adoption.

Transport Secretary Heidi Alexander said the investment would back UK firms, create skilled jobs and help decarbonise flying while improving air quality.
