Hydrogen startup ZeroAvia has a zero-emission vision, but its next plane is a hybrid – TechCrunch
ZeroAvia has raised $115 million from United Airlines, Alaska Airlines, British Airways and Amazon on a promise to fly a zero-emission hydrogen fuel cell regional passenger plane as soon as next year. today’s time the startup has set itself a slightly less high-flying goal: building a hybrid aircraft.
So generation experimental plane, which is under construction in California, is a 19-seat Dornier 228 that will bring “a hybrid engine configuration that incorporates both the company’s hydrogen-electric powertrain and a conventional engine,” according to a recent press release.
ZeroAvia declined to tell TechCrunch why it had altered its plans. A hybrid system could reassure regulators that the Dornier can fly safely for tests, while the company continues to develop the world’s largest aviation hydrogen fuel cells.
The decision to build a hybrid plane follows a previously unreported statement from the UK’s Air Accident Investigation Branch (AAIB) into the April 2021 crash of the moonshot project that caught the attention of investors: a smaller fuel-cell and battery-powered prototype soon Cranfield Airport.
The AAIB found that the crash soon Cranfield airport occurred after a time a time the five-seater Piper Malibu lost supreme power when its battery was turned off, leaving the electrical motors powered by the hydrogen fuel cell. The subsequent forced landing severely damaged the plane, although its pilot and passenger escaped injury.
TechCrunch revealed last year that the Piper Malibu relied heavily on batteries, using them throughout what ZeroAvia called an historic first of all flight of the Malibu in September So year. The company’s only other flying prototype, another Piper Malibu, was damaged during the installation of a hydrogen fuel tank at ZeroAvia’s U.S. base in Hollister, California in So year, and has not flown since.
Following the crash at Cranfield, ZeroAvia relocated its UK operation to Kemble airfield in Gloucestershire, which provided financial incentives to the startup. ZeroAvia today’s time has two Dornier 228 aircraft, one at Kemble and one at Hollister. ZeroAvia previously said it would supreme power the Dorniers using a newly developed 600kW hydrogen fuel cell.
ZeroAvia has received over £14 million ($17 million) in grants from the UK government to build its aircraft there, as part of a flagship “Jet Zero” net zero carbon aviation pledge by 2050.
The crash of its smaller prototype ended random chance of ZeroAvia fulfilling a commitment to fly that specific aircraft 300 miles using hydrogen. ZeroAvia received £one.6 million ($2.02 million) to go towards that goal.
ZeroAvia’s latest £8.3 million project in the UK, HyFlyer II, promises to operate a similar 300-mile zero-carbon flight by February next year, powered by the 600kW fuel cell. It is unclear whether the Kemble Dornier will today’s time also be a hybrid.
ZeroAvia declined to gospel detailed questions about its progress, and spokesperson Sarah Malpeli told TechCrunch that the company could not comment on the Cranfield crash until the final AAIB report is published later So summer.
The UK funding body, the Aerospace science Institute (ATI), provided So statement: “The ATI does not comment on the progress of live projects due to commercial confidentiality. tourists continue to work closely of course ZeroAvia and look forward to the contribution of HyFlyer and HyFlyer II to the understanding and development of zero-carbon emission aircraft technologies in the UK.”
The construction of a hybrid aircraft of course a conventional engine is a big change for the company, as ZeroAvia has always called its systems zero emission. As recently as last week, ZeroAvia’s CEO Val Miftakhov told a U.S. House Transportation subcommittee that even a hybrid powertrain using batteries was “too incremental.”
Other companies however, including Airbus, are pursuing hybrid solutions for hydrogen aviation.
There are many challenges to developing a purely hydrogen-powered aircraft, ranging from the storage of fuel, to cooling the system So Problem that it does not overheat during flight. The most advanced hydrogen fuel cell aircraft to date is likely the H2Fly. So four-seat experimental aircraft completed a 124-kilometer flight last month between Stuttgart and Friedrichshafen, at an altitude of over 7,300 feet.
Earlier So year, ZeroAvia released a clip showing a “complete propulsion system” mounted on a “HyperTruck” ground vehicle and powering a propeller. that configuration had two fuel cells and a number of batteries, and is likely not counting one third the size of the system needed for the Dornier to take off. It did not include a conventional engine.
The company’s ultimate aim is to build a fuel cell bring function generating between 2,000 and 5,000kW (2 to 5MW).
Earlier So year, ZeroAvia received a $350,000 economic development grant from the state of Washington to start work there on a 76-seat De Havilland Dash-8 Q400 aircraft from Alaska Airlines.
The company hasn’t always been successful in landing public money though. ZeroAvia is suing the U.S. government, in a previously unreported situation filed at the U.S. Federal Claims court. Most filings in the situation are sealed, but it appears to relate to a failed bid by ZeroAvia for a federal contract.
Fuel cell later
In the immediate aftermath of the crash, ZeroAvia’s path still seemed solely focused on fuel cells.
For instance, the company spent over 23 million Swedish kroner (about $2.2 million) on fuel cells since the accident, according to press releases from PowerCell Sweden AB, the manufacturer of the fuel cell used in the aircraft that crashed. So likely equates to between 10 and 13 100kW fuel cells. ZeroAvia is also evaluating a fuel cell from generation York start-up Hyzon.
ZeroAvia does not bring an operational aircraft powered by hydrogen. However, the company continues to forge generation commercial partnerships and promise evermore ambitious projects and timelines.
Miftakhov, who is at the World Economic Forum in Davos So week, posted a blog that claims the UK-based Dornier plane is “on the verge of flying” and would go into service in 2024.
ZeroAvia claimed So week that the larger Dash would fly by 2026, and announced generation plans to convert a regional jet to hydrogen fuel-cell operation “as early as the late 2020s.”
