The air transportation business is on route to using more sustainable fuels, although there has been a delay because of low oil prices. While that delays the urgency to invest in alternative sources of energy, some reason that the sheer number of flights over a decades of flying will justify the cost.
“It’s very urgent to develop these alternative fuels,” said Michel Wachenheim of the International Coordinating Council of Aerospace Industries Associations (ICCAIA), in a story posted in Phys.org.
“There is no reason to be satisfied with the situation.”
The commercial airline industry has committed itself to cutting its carbon emissions, although it says that there is a lack of public incentives. With that, though, the general goal is to keep carbon releases at 2020 levels in 2035.
A mix of biofuels and jet fuel is one answer.
That’s one of the favored by the International Civil Aviation Organization, Phys.org says. And lighter and more fuel efficient aircraft is also part of the mix, it adds, noting that life-cycle performance is the key measure.
“The ultimate goal is to make a fuel-equivalent to jet fuel, but those processes still are under development or at an early stage of industrial production,” the story says. Hydro-treated oils is one of the emerging fuels. It converts gases into hydrocarbons.
It’s all being researched with, of course, cost and safety at the top of the concerns at hand.
