CSIRO finds hydrogen could reduce aviation emissions within 5 years

Green Car Congress

A new report from Australia’s national science agency CSIRO shows that clean hydrogen can significantly reduce aviation emissions with potential benefits seen within five years. This involves the replacement of on-airport ground support equipment, currently running on liquid fuels and batteries, with hydrogen powered fuel cell alternatives.
