China's high-tech, energy-efficient aircraft engines showcased at Zhuhai Airshow

China's domestically developed aircraft engines are capturing the limelight at the ongoing 15th China International Aviation and Aerospace Exhibition in the southern coastal city of Zhuhai, wowing visitors with their cutting-edge technologies and energy-efficient designs.

The exhibition kicked off in Zhuhai City of Guangdong Province on Tuesday, showcasing the latest in aircraft, spacecraft, and weaponry, along with impressive aerial performances.

Among the attention-grabbing exhibits, a number of innovative aircraft engines are demonstrating China's gains in this competitive and fast-evolving industry, spanning the gamut from fighter jet engines to those for civilian aircraft.

As an important aviation enterprise, Aero Engine Corporation of China, or AECC, is engaged in the development, production and maintenance of aircraft engines, gas turbines, and more. Its turbojet engines, turbofans, and turbo-shafts have been widely installed in various types of military and civilian aircraft.

The company's star product, the AEF1200, debuted at the event, catching eyes with its sheer size. It is the country's first self-developed high bypass ratio dual rotor turbofan engine, a highly efficient type of jet engine that uses two sets of rotating blades to compress air, with most of the air bypassing the engine core to create thrust more quietly and with better fuel efficiency. This design will help China's large airplanes fly farther on less fuel while keeping engine noise down.

AECC also displayed new engines designed for helicopters and drones, which are expected to be increasingly important in coming years.

"Our AES100 engine is an advanced turbo-shaft engine independently developed by AECC in response to the national call for the development of the low-altitude economy, which is energy-saving and environmentally friendly. It is equipped with a very useful health-monitoring system. So, its stability and reliability can also be assured. The AEP100 is a 900-kilowatt turboprop engine developed by us using a turboshaft engine. It can also be used in drones, business jets, and trainer aircraft," said Liu Jie, a staff member at AECC.

Since its launch, the event, also known as Airshow China, has been one of the top five airshows worldwide. This year, nearly 900 enterprises from 47 countries and regions are participating, with 149 of them global attendees.

A carbon dioxide (CO2) capture and liquefaction facility now runs smoothly in south China's Hainan Free Trade Port (FTP), signaling a major technological advance in the region's push toward green and low-carbon development.

The facility, located in Hainan's Chengmai County, was developed by Southern Petroleum Exploration and Development Corporation -- a Hainan-based subsidiary of China National Petroleum Corporation (CNPC) -- which focuses on oil and gas exploration and new energy development.

It captures, purifies and liquefies CO2 extracted from associated oilfield gas, with daily output of liquid CO2 now surpassing 100 metric tonnes.

"To date, our pilot project has cumulatively stored 360,000 tonnes of CO2 while boosting oil and gas output by 150,000 tonnes. This is equivalent to offsetting the annual carbon emissions of about 150,000 cars," said Wang Haisheng, executive director of Southern Petroleum Exploration and Development Corporation.

Building on its successful industrialization of carbon capture, utilization and storage (CCUS), the corporation is now pioneering advanced carbon storage technologies.

By refining capture technology and implementing a multi-dimensional monitoring network, the project has achieved long-term and stable CO2 storage, solidifying the foundation for a safe and low-carbon energy system in Hainan.
