CATL Successfully Testing Condensed Batteries in Electric Aircraft

CATL announces electric aircraft range breakthrough and advances in sodium-ion battery technology, revolutionizing sustainable air travel. At the 15th Annual Meeting of the New Champions of the World Economic Forum, CATL’s chairman, Robin Zeng, made a groundbreaking announcement that could reshape the future of aviation. CATL tweeted on the X platform: „Another focus of our technology development is high energy-density batteries. Our condensed batteries, achieving up to 500 watt-hours per kilogram, are currently being tested in planes, allowing 4.0-ton aircraft to take off. We aim to support 8.8-ton aircraft next. By 2027 or 2028, we expect four-seater private jets to use these batteries, with a standardized range of 2,000 to 3,000 kilometers, making them feasible for private and business jets.“

CATL’s significant progress in their civil, electric manned aircraft cooperation project marks the first public disclosure of the range capabilities of CATL’s electric aircraft, highlighting a substantial advancement in aviation technology. According to the company, the 8-ton model is expected to be operational between 2027 and 2028, featuring a range that could revolutionize regional air travel. The key to this advancement lies in CATL’s cutting-edge condensed-state battery technology, boasting an energy density of 500Wh/kg. This energy density is double that of current electric vehicle (EV) power batteries, which typically offer around 250Wh/kg and meet the strict energy requirements for regional aircraft.

This development signifies a significant leap in the aviation industry, potentially leading to more sustainable and efficient air travel options. The high energy density of the batteries means that electric aircraft could become a viable alternative to traditional fossil fuel-powered planes, significantly reducing carbon emissions and operating costs.

New generation of sodium-ion batteries
In addition to developing electric aircraft, CATL is also focusing on enhancing its battery technology across various applications. During his participation at the Annual Meeting of the New Champions, Zeng also disclosed that the company is advancing its sodium-ion battery technology, which is expected to offer better cost, lifespan, and low-temperature operation performance, with the anticipated growth and potential of sodium-ion batteries. According to Zeng, these batteries could be launched as early as next year, with the technology already at a developmental stage rated at level 7 out of 10. He stated, “This new generation of sodium-ion batteries will help not only in terms of cost but also on the low-temperature performance.”

With the introduction of condensed state and sodium-ion batteries, the potential applications range from more efficient EVs to advanced energy storage solutions. CATL’s progress in electric aircraft development underscores its role in driving forward sustainable technologies. As the aviation industry looks towards a greener future, CATL’s electric aircraft could be a game-changer, offering a glimpse into a future where air travel is both efficient and environmentally friendly.

The future of electric aviation holds immense promise, with potential benefits including reduced carbon emissions, lower operating costs, and increased efficiency. As technology advances, the vision of electric-powered flights becoming a mainstream mode of transportation is increasingly within reach. Innovative efforts like the ones by CATL pave the way for a new era in aviation, where sustainable and efficient air travel becomes a reality, ushering in a cleaner and greener future for the aviation industry.

CityAirbus NextGen makes its debut

Schreibe eine Antwort

Airbus recently presented its full electric CityAirbus NextGen prototype to the public, ahead of its maiden flight later this year. The two-tonne class CityAirbus, with a wing span of approximately 12 metres, is being developed to fly with an 80 km range and to reach a cruise speed of 120 km/h, making it perfectly suited for operations in major cities for a variety of missions.

The unveiling coincided with the opening of the new CityAirbus test centre in Donauwörth, which will be dedicated to testing systems for electric vertical takeoff and landing vehicles (eVTOLs). The centre, which is part of Airbus’ ongoing and long-term investment in Advanced Air Mobility (AAM), began its operations with the CityAirbus NextGen’s power-on in December 2023 and it will be now used for the remaining tests required before the prototype’s maiden flight later in the year. These tests cover the electric motors with their eight rotors as well as the aircraft’s other systems such as flight controls and avionics.

At the same time, Airbus is expanding its global network and partnerships to create a unique ecosystem that will foster a successful and viable AAM market. Airbus recently signed a partnership agreement with LCI, a leading aviation company, to focus on the development of partnership scenarios and business models in three core AAM areas: strategy, commercialisation and financing.

World’s First Piloted Flight of Liquid Hydrogen Powered Electric Aircraft

Schreibe eine Antwort

Project HEAVEN, a European-government-supported consortium assembled to demonstrate the feasibility of using liquid, cryogenic hydrogen in aircraft, today announced it has successfully completed the world’s first piloted flight of an electric aircraft powered by liquid hydrogen. The consortium is led by H2FLY and includes the partners Air Liquide, Pipistrel Vertical Solutions, the German Aerospace Center (DLR), EKPO Fuel Cell Technologies, and Fundación Ayesa.

The day consisted of four flights powered by liquid hydrogen as part of the project’s flight test campaign, including one flight that lasted for over three hours. The flights were completed with H2FLY’s piloted HY4 demonstrator aircraft, fitted with a hydrogen-electric fuel cell propulsion system and cryogenically stored liquid hydrogen that powered the aircraft.

Results of the test flights indicate that using liquid hydrogen in place of gaseous hydrogen will double the maximum range of the HY4 aircraft from 750 km to 1,500 km, marking a critical step towards the delivery of emissions-free, medium- and long-haul commercial flights.

Besides project HEAVEN, the work has been funded by the German Federal Ministry for Economic Affairs and Climate Action (BMWK), the German Federal Ministry for Digital and Transport (BMVD), and The University of Ulm. Compared with pressurized gaseous hydrogen storage (GH2), the use of liquified, cryogenic hydrogen (LH2) enables significantly lower tank weights and volume, therefore leading to increased aircraft range and useful payload.
