VIVAERO Hybrid engine could reduce aviation emissions by up to 30% In the future, regional flights such as Trondheim-Oslo could become much more environmentally friendly with the help of a hybrid aircraft engine . This type of engine combines an electric motor and a combustion engine to drive a propeller. The innovation should be able to reduce CO2 emissions by up to 30%. "The principle that causes emissions to decrease is the same as for hybrid cars—that is, a combination of both fuel and electricity," says SINTEF researcher Torstein Grav Aakre . Aviation accounts for about 4% of the EU's total climate emissions . This solution has the potential to reduce emissions by as much as 1% throughout the EU, according to the researcher. Focus on regional flights...The focus is on regional flights because it is easier to make these flights greener using electricity. "The reason is that batteries for electric engines weigh more than regular fuel. And the longer you have t...
