The long-term sustainable growth of air transport will hinge on the development of net zero carbon propulsion technologies and NASA has taken a concrete step toward fostering the development of one such option.

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.
