Airbus on Thursday broke ground on its second final assembly line in North China's Tianjin municipality as the European aircraft manufacturer seeks expansion on the Chinese market.
France-headquartered aircraft manufacturer Airbus said China has the huge capability of producing sustainable aviation fuels, and it will continue to strengthen cooperation with Chinese suppliers to promote the use of SAF to contribute to the sustainable growth of the aviation industry.
Airbus said nearly all the airlines in China have expressed an interest in using SAF and the plane maker plans to further promote its use in the delivery flights of aircraft at its final assembly line in Tianjin.
By the end of this year, its new aircraft lifecycle service center in Chengdu, Sichuan province, is expected to be put into operation.
"We need to look at the overall lifecycle of the aircraft from design, supply chain, operations, maintenance and end-of-life recycling.
We will be able to recycle 90 percent of the weight of an aircraft.
Meanwhile, Airbus' research center in Suzhou Industrial Park in Suzhou, Jiangsu province, opened in April, which focuses on the research of the infrastructure for its futuristic hydrogen-powered aircraft.
"Our ambition is to have the first hydrogen-powered aircraft in service by 2035.
We are working to create a supportive ecosystem to ensure the storage, distribution and availability of green hydrogen can supply the commercial aircraft, and that's going to take time," Kitcher said.
The airline has ordered 72 Boeing B787 widebody aircraft and plans to order more single-aisle planes to expand its fleet.
SF Airlines, the aviation branch of logistics giant SF Express, has been expanding its freighter fleet, reaching 84 aircraft in July.
YTO Express, another parcel delivery company, said its air cargo fleet reached 11 aircraft by the end of last year.
另一家包裹递送公司YTO Express表示,截至去年年底,其航空货运机队已达到11架。

- Airbus has delivered more than 630 A320 family aircraft assembled at its Final Assembly Line Asia (FALA) in North China's Tianjin municipality over the past 15 years, according to the European aircraft manufacturer.
In November 2021, Airbus revealed its plans to expand the capabilities of FALA in Tianjin to accommodate A321 production, responding to rising market demand for the aircraft type.
In March 2023, Airbus delivered the first A321neo aircraft assembled at FALA in Tianjin to China's Juneyao Air.
In April, Airbus entered into an agreement with its Chinese partners to enhance the final assembly capacity for its A320 family aircraft with the addition of a second final assembly line planned at the same site.
By then, Airbus will have 10 A320 family aircraft final assembly lines worldwide, including two in Tianjin, according to Airbus.
Commercial Aircraft Corp of China, or COMAC, will deliver the third Chinese-developed C919 aircraft next month to China Eastern Airlines, sources at the Shanghai-based airline told local media.
"China Eastern is scheduled to receive its third C919 in October, and a few more new flights are going to be launched before June next year, to enable more Chinese passengers to take flights on the Chinese-developed passenger aircraft," an executive in charge of the airline's aircraft operations was quoted as saying by local media Jiefang Daily on Thursday.
The aircraft's maiden commercial flight was from Shanghai Hongqiao International Airport to Beijing Capital International Airport on May 28.
As C919 flights increase, the experience gathered would help in making future Chinese aircraft safer, thus helping its manufacturer COMAC to meet market demand better, Zheng said.
Aircraft manufacturer vows to increase investment to expand supply chainEuropean aircraft manufacturer Airbus said it would continue to increase investment in China, its largest single-country market, and expand its supply chain in the country by cooperating with more Chinese suppliers, including startups, driven by China's strong demand for new aircraft and rapid recovery of the air travel market.
Opened in 2008, the facility serves as the first Airbus commercial aircraft assembly line outside of Europe.
In the meantime, the second C919, China's first self-developed narrow-body aircraft, was put into commercial operation by China Eastern Airlines in August, serving travelers between Shanghai and Chengdu, Sichuan province.
It recently announced an order for an additional 32 Airbus single-aisle aircraft, including A321neo and A320neo, which are expected to join the fleet by 2029.
The Aviation Industry Corporation of China (AVIC), the nation's major aircraft maker, has held a series of educational activities to promote Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era.
China Eastern Airlines, the aircraft's first global customer, received the second C919 on July 16.
China Eastern received the very first C919 on Dec 9, 2022, and the aircraft accomplished its maiden commercial flight from Shanghai Hongqiao International Airport to Beijing Capital International Airport on May 28.
European aircraft manufacturer Airbus has again raised its forecast for aircraft demand in China, saying that over the next 20 years, Chinese carriers are expected to acquire 9,440 new airplanes to meet expanding commercial air travel demand.
By 2042, the global fleet size of cargo aircraft in service is likely to reach 3,230, including 920 newly manufactured planes and 1,590 freighters that are converted from passenger aircraft, Airbus projected.
Now, it has a fleet size of over 50 aircraft, including widebody B787 and single-aisle A320 family aircraft.
