French president Emmanuel Macron says the first commercial aircraft relying on hydrogen should be in service by 2030, earlier than Airbus’ stated target of 2035.

A shift from electric and hybrid-electric propulsion toward hydrogen is evident among sustainable aircraft projects announced so far this year, according to European consultancy Roland Berger.

U.S. startup Prometheus Fuels expects to begin delivering commercial quantities of its carbon-neutral sustainable aviation fuel toward the end of 2022.

The aim of the collaboration is to reduce the weight and improve the durability of HyPoint’s hydrogen fuel cell.

A project to demonstrate low-carbon production of sustainable aviation fuel from corn stover—the leaves and stalks left in fields after harvesting—has been funded by the U.S. Energy Department.

Underlining that advanced air mobility has become a driver for new technologies in aviation, Honeywell has introduced Anthem, its fifth generation of integrated flight deck, with electric air taxi developers Lilium and Vertical Aerospace as launch customers.

GE Aviation says it will use a modified Saab 340B regional airliner as a flying testbed for hybrid electric propulsion technology to be evaluated as part of NASA’s Electric Powertrain Flight Demonstration (EPFD) program.

NASA has awarded contracts to GE Aviation and MagniX for the Electric Powertrain Flight Demonstration (EPFD) program, which aims to mature megawatt-class electrified aircraft propulsion (EAP) technologies for regional and single-aisle transport aircraft from 2035 onwards.
