ZeroAvia H2 Hybrid Plane Ready For Test Runs

Their headline is a bit misleading. These tests will have jet engines on one side and H2 power cells running the other side. If all goes well, then they move into 100% H2 powered planes.

Canary Media headline: ZeroAvia’s hydrogen-powered test plane is nearly ready for takeoff

Subheadline: The California startup will fly its 19-seat prototype in the U.K. and U.S. this summer as the aviation industry searches for zero-emissions fuels.
22 June 2022…

Airports worldwide are swarming with travelers paying sky-high fares for jampacked flights this summer. Far away from those chaotic hubs, however, is a small airfield in the English village of Kemble. At a single working runway surrounded by farms and grazing sheep, aviation experts are preparing to launch a different kind of trip, one that’s powered partly by hydrogen.

The startup ZeroAvia is planning to flight-test a 19-seat aircraft equipped with hydrogen fuel cells in mid-July at the Cotswold Airport in Kemble, the company says. A second test-bed plane will take flight in the coming months near ZeroAvia’s headquarters in Hollister, California. The two dual-engine aircraft will use fuel cells — which convert hydrogen into electricity to drive propellers — and batteries on one side, while the other side will use a conventional jet engine.

If all goes smoothly, the demonstrations could play a key early role in advancing hydrogen as an alternative to highly polluting, oil-based jet fuel. So far, hydrogen has only been tested a handful of times in tiny, single-digit-passenger prototype models. Yet major aviation companies are increasingly considering the carbonless fuel as a long-term solution for cleaning up the notoriously hard-to-decarbonize industry.

The test flights will follow a flurry of recent hydrogen-related developments. Delta Air Lines is partnering with Airbus, the world’s largest aircraft manufacturer, to develop a hydrogen-powered passenger plane and explore how to store and supply hydrogen at airports. Airbus itself is building a demonstration engine to test hydrogen propulsion in one of its A380 superjumbo jets. Universal Hydrogen, a Los Angeles–based startup, is building hydrogen planes as well as portable storage capsules designed to replace traditional pipes and hoses. The company plans to test its 1-megawatt fuel-cell powertrain in a 40-passenger plane in September near Moses Lake, Washington.
