In a bid to reduce their emissions, some of the world’s biggest aircraft makers have turned to scrap aircraft engine parts to make their planes more fuel efficient.
But is the effort worth it?
We take a look at the latest news on the industry and how it’s working.
1 / 2 How to get started: Here’s a look to start using parts in your aircraft:The World Economic Forum in Davos, Switzerland, last week announced that the world will have a net reduction of 1.2 gigatonnes of carbon dioxide by 2030, the first time that’s happened in the past 200 years.
The reduction is being achieved through emissions reductions, efficiency gains and carbon sequestration.
“This means we can cut emissions by more than 1.5 gigatonne (GtCO2) per year in 2030,” said World Economic Roundtable chief economist Adam Voiland.
“That is not only a significant and sustainable reduction, it is also an unprecedented achievement in terms of the global economic and social implications.”
To put that in context, the US has already been reducing its CO2 emissions by nearly one tonne per year since 2007, according to the US Environmental Protection Agency (EPA).
That means the industry could be expected to see its emissions fall by more half a tonne in the next five years.
However, that’s not quite the same as a global emission reduction, because a world of 5.2Gt CO2 in 2030 is still going to be greater than the US emissions reduction.
“There are many factors in play, including the economies of scale of our industry, as well as how many aircraft we have to produce, the cost of the components and the availability of resources to do the work,” said John Lydon, managing director of Clean Air Network, a group that campaigns against air pollution.
“However, it seems clear that this is a very achievable and achievable goal and that the technology is on its way to meeting it.”

That’s partly due to a shift in the industry from fossil fuels to renewable energy.
According to the International Centre for Sustainable Development, the world is currently producing roughly 15GW of renewable energy and it’s expected to increase to over 40GW by 2020.
“The vast majority of the demand for these aircraft engines are in China, Indonesia and India, and it is projected that the global demand for aircraft engines will reach 50GW by 2030,” the group said in its 2017 Global Energy Outlook report.
“The demand for oil, natural gas and coal is also growing, but will not be able to match the growth of the aircraft engine industry.”
The biggest oil producers in the world are also shifting to renewable sources of energy.
In March 2017, the International Energy Agency reported that a third of the new oil produced each year in the developing world is derived from renewable sources.
That is expected to rise to 40GW in 2020, up from 22GW in 2021.
“Wind turbines are also an excellent energy storage solution for aircrafts,” said Voilan.
“They can store energy for the aircraft and then take the energy when the engine needs to be recharged.
It’s an incredibly flexible and resilient system.”
But the biggest fuel savings of all, according the IEA, is in the aircraft itself.
“For aircrafts, there is no net fuel savings in the production of aircraft engines because the engines themselves are more than 50% less efficient,” said Lydons research director at Clean Air Networks, Tom Smith.
“With aircrafts being much larger, the engines have a smaller area to store the fuel and also are much more expensive to produce.
And aircrafts are also much more fragile and susceptible to weather changes.”
For example, in 2019, a typhoon wiped out most of the fleet of Airbus A330 aircraft at Heathrow Airport in the UK.
The storm caused massive damage and a record-breaking number of aircrafts to be grounded.
But Lydonian told Business Insider the engines are still able to deliver the same performance that aircrafts would have achieved in a hurricane.
“An aircraft engine can perform much better in a storm, it’s more stable,” he said.

So it’s not a big win in a tropical storm, but it’s a big victory in a cyclone.”

This is where the fuel is ignited.
The chamber can be built to run on an existing engine or it can be constructed entirely from components.
The new fuel chamber from General Electric is the first to use this type of combustion chamber technology.
The main components are the turbine blades, the combustion chambers and the electric motors, which generate electricity
