How can I make air travel more environmentally friendly?This Rolls-Royce pledge is a big part of the answer | Business News

This is one of the biggest challenges facing the world as it seeks to move to the future of Net Zero and is a way to make aviation more environmentally friendly.

The global commercial aviation industry currently produces 2-3% of all anthropogenic carbon dioxide emissions, accounting for about 12% of CO2 emissions from all sources.

Therefore, the industry will play an important role in the transition, especially as the demand for air travel is expected to increase significantly as society prospers around the world.

Therefore, we are looking for ways to reduce the carbon intensity of air travel.

Rolls-Royce has taken a decisive step in that direction today as it announced that by 2023 all torrent engines would prove compatible with 100% sustainable aviation fuels. The torrent family of engines powers about 40% of the world’s long-haul aircraft.

Warren East, CEO of Rolls-Royce, did not reveal how much it cost to adapt the Trent family.

But he told Sky News:

“We want to continue to provide engines for long-haul aviation, so that’s what we have to do.”

Previously, sustainable aviation fuels produced from raw materials such as cooking oil, non-palm waste oil from plants and animals, and solid waste from homes and businesses “have at least 75% less net CO2 lifecycle emissions.” It states. Conventional jet fuel “.

The Rolls-Royce Trent XWB engine is manufactured at the company’s factory in Derby.

However, the big question that airlines and aircraft manufacturers have is how the engine works when the fuels are different.

East said making the engine compatible with 100% sustainable aviation fuel would not affect engine performance.

By 2050, he said, with all long-range aviation powered by sustainable aviation fuels, there would have been an evolution in the way products were manufactured.

“Sustainable aviation fuels have the potential to further improve engine performance,” he added.

Another question is about the cost of sustainable aviation fuel. At present, it is almost not manufactured at eight times the price of kerosene. Currently, only 0.05% of the jet fuel used in the world is sustainable, making it difficult for airlines to buy even if they want to.

It should change over time. Royal Dutch Shell today worked with Rolls and Airbus to call for closer cooperation with the entire aviation sector and with the government, enabling the transition of long-haul aviation to Net Zero. Recently, it has promised to increase production to 2 million tonnes of sustainable aviation. Fuel every year by 2025. This is more than 10 times the total amount of sustainable aviation fuel produced in the world today.

Although purchasing sustainable aviation fuel is a problem for airlines, East said oil and gas companies are not the only ones to meet demand or reduce costs.

He added: “[There are] What you can do in the industry by providing an engine. Due to the increased efficiency of the step function, for example, the XWB engine currently onboard the A350 is significantly more efficient than the older engine.

“The next-generation engine, the Ultrafan engine, which we expect to fly in the mid-2030s, is about 25% more efficient than the original Trent engine, so we can do something in terms of efficiency.

“And there are significant cost savings in sustainable aviation fuel scaling.

“Today, less than 1% of the world’s fuel is sustainable aviation fuel. By 2030, the industry will be signed up to 10%, which means that the amount of aviation used by then will increase 400-fold. Increasingly, some kind of scale-up will definitely have a positive economic effect. “

At today’s event in Derby, Mr. East was accompanied by Sabine Klauke, Chief Technology Officer of Airbus, one of Rolls’ key customers. Currently, all aircraft can operate on a mixture of up to 50% sustainable aviation fuel, and the company said it will work closely with its partners to accelerate this to 100% by 2030.

She told Sky News: “Airbus has great ambitions … we have a zero-emission program to bring two zero-emission aircraft into service by 2035. We will pull them together.”

Airbus not only puts all the eggs in one basket, but is also marked as a sustainable aviation fuel. Manufacturers are also doing a lot of work on hydrogen as a vehicle, unlike rival Boeing, which appears to be keen on sustainable aviation fuels. Airbus CEO Guillaume Foley previously said he would support the latter only as a short-term alternative to hydrogen.

But obviously, the aviation sector is trying to reduce carbon emissions by the end of the last decade, so sustainable aviation fuels will be doing most of the hard work.

Rolls-Royce wants the government to approve a small modular reactor to support the UK’s commitment to zero-carbon power generation.

Today’s announcement from Rolls is behind a series of recent developments that have raised expectations for the company after a cruel period in which profits were lost due to the decline in air travel as a result of a pandemic.

last month Earn $ 2.6 billion (£ 1.9 billion) A contract from the US Air Force has been awarded to Rolls to replace the engine of the Boeing B-52H Stratofortress bomber fleet. Recent AUKUS security agreements between Australia, the United Kingdom and the United States also expect the latter two vessels to share nuclear technology to power the former submarines. May bear fruit on bread rolls..

Mr. East said: [UK’s] The nuclear fleet of the last 60 years has clearly had a lot of UK-specific expertise, but it is up to the government to decide who will do what with this when it comes to implementing that agreement. “

At least as big an award would potentially be government approval for a small modular reactor to support Britain’s efforts to generate zero-carbon energy.

“I’m absolutely hoping to see something at the end of the decade,” East added.

Investors will certainly want that. Perhaps the government is pushing Britain towards a net-zero future?
