Aerospace giant Airbus is to conduct test flights to study the composition of contrails left by zero-emission hydrogen-powered planes, the company announced Wednesday at the Farnborough Air Show.

The project, named Blue Condor, is part of efforts to bring a hydrogen-combustion plane into service by 2035 to try to eliminate CO2 emissions, the main gas responsible for the greenhouse effect.
