Dovetail Electric Aviation has begun tests of an integrated hydrogen fuel-cell powerplant targeted at flight tests on a modified Beechcraft King Air.

The first flight of the ERA is scheduled for 2026 and entry into service for 2028.

Two-thirds of Europe’s Clean Aviation research projects are focused on more sustainable advanced propulsion technologies for service entry in the mid-2030s.

Beta’s Alia electric aircraft has participated in a U.S. Air National Guard exercise.

The GoAero organization has launched a competition to develop and test a vertical-takeoff-and-landing aircraft in simulated emergency response missions.

Daher says the hybrid-electric Ecopulse demonstrator has now logged 1.5 hr. of flight testing in full electric mode.

U.S.-European startup Cosmic Aerospace has raised $4.5 million in seed financing to progress development of a 24-passenger all-electric regional aircraft.

The aircraft propulsion system is powered by hydrogen fuel cells in combination with a booster battery pack that is used during peak power demands.
