Propulsion startup ZeroAvia conducted the first flight of its hydrogen-electric powertrain on a Dornier 228 testbed from Cotswold Aircraft, England, on Jan. 19. 

The aircraft flew for 10 min. with the 600-kW ZA600 fuel-cell propulsion system replacing the 19-seat regional turboprop’s left-side turboprop. With a weight at takeoff of 5,650 kg (12,450  lb.), the modified 228 is the largest and heaviest aircraft yet to fly with hydrogen-electric propulsion.
 

Airlines using Belgian airports will have easier access to SAF in the future after NATO began allowing the use of its pipeline network to transport it. Liège and Brussels airports said an agreement had been reached to use the military alliance’s Central Europe Pipeline System (CEPS) to transport SAF from fuel manufacturer Neste’s blending facility in Ghent. Brussels Airlines marked the occasion with a symbolic first flight Jan. 1 from Brussels to Malaga, Spain, that used some of the first SAF transported by CEPS
 

Air France-KLM issued the first sustainability-linked bond, which attracted strong investor interest amounting to around €1 billion ($1.08 billion) and an order book of around €2.6 billion.

Virgin Atlantic plans to operate the first-ever 100%-sustainable aviation fuel (SAF) powered transatlantic flight by the end of this year. The London Heathrow-New York JFK flight will use a Boeing 787 powered by Rolls-Royce Trent 1000 engines. The SAF will be made primarily from waste oils and fats, such as used cooking oil. Virgin Atlantic CEO Shai Weiss said research and data from the flight would provide “a huge step in fast-tracking SAF use across the aviation industry and support the investment, collaboration, and urgency needed to produce SAF at scale.” 
 

All Nippon Airways (ANA) and Japan Overseas Infrastructure Investment Corporation for Transport & Urban Development (JOIN) signed an MOU to mutually cooperate on initiatives aimed at manufacturing and procuring sustainable aviation fuel (SAF) overseas. 

ANA will provide advice and other support to JOIN’s SAF projects overseas, based on its experience and know-how in the aviation business, and JOIN will work to secure and increase ANA’s opportunities to stabilize its procurement of SAF by expanding investments in the SAF projects as well as actively working to supply SAF from the projects to ANA.
 

Sunan Ruili Airlines signed an agreement with Embraer to join the Energia Advisory Group, making it the first Chinese carrier to participate in the electric aircraft project.
