World’s most efficient passenger plane gets hydrogen powertrain

The Celera 500L is a truly remarkable design. Otto Aviation says its odd shape delivers an astonishing 59 percent reduction in drag, and a massive leap in efficiency and range compared to traditional plane geometries. Arguably, this thing should’ve bee… Continue reading World’s most efficient passenger plane gets hydrogen powertrain

First ammonia-powered jet flight in 2023: A roadmap to clean aviation

The entire airline industry needs to wean itself off jet fuel over the next few decades – but it’s still buying enormously expensive jet aircraft that are expected to keep bringing home the bacon for more than 20 years. Australian company Aviation H2 h… Continue reading First ammonia-powered jet flight in 2023: A roadmap to clean aviation

Ultra-light liquid hydrogen tanks promise to make jet fuel obsolete

A revolutionary cryogenic tank design promises to radically boost the range of hydrogen-powered aircraft – to the point where clean, fuel-cell airliners could fly up to four times farther than comparable planes running on today’s dirty jet fuel.Continu… Continue reading Ultra-light liquid hydrogen tanks promise to make jet fuel obsolete

Hydrogen-electric HY4 passenger aircraft sets altitude record

Stuttgart-based German aerospace company H2FLY has claimed a new world record for its four-seater HY4, which became the first hydrogen-powered passenger aircraft to reach an altitude above 7,000 ft (2,134 m) on April 13. In addition, the HY4 made the f… Continue reading Hydrogen-electric HY4 passenger aircraft sets altitude record

Piasecki outlines its path to the world’s first manned hydrogen helicopter flight

Piasecki Aircraft has announced it’s putting a HyPoint turbo air-cooled fuel cell and an electric powertrain into an ultralight helicopter from EDM Aerotec, hoping to achieve the world’s first manned hydrogen-powered helicopter flight – with its own co… Continue reading Piasecki outlines its path to the world’s first manned hydrogen helicopter flight

Hyundai outlines its hydrogen aviation plans, including regional eSTOLs

Hyundai has already made it very clear that it’s making a serious play at next-gen electric aviation, establishing its own eVTOL subsidiary Supernal late last year and promising to flex its automotive-grade manufacturing muscle to get air taxis built i… Continue reading Hyundai outlines its hydrogen aviation plans, including regional eSTOLs

Reusable scramjet launch system to pave way for hypersonic airliners

Australian company Hypersonix Launch Systems is not only looking to make the delivery of satellites into orbit cheaper and more accessible, but also greener. It is developing a reusable launch system powered by green hydrogen that would deliver small s… Continue reading Reusable scramjet launch system to pave way for hypersonic airliners

De Havilland will develop and market hydrogen airliners with ZeroAvia

De Havilland Canada has partnered with ZeroAvia to develop a zero-emissions hydrogen fuel cell powertrain for its Dash 8-400 airliner, which can either be retrofit to existing planes or supplied as a factory option on new aircraft orders.Continue Readi… Continue reading De Havilland will develop and market hydrogen airliners with ZeroAvia

Could hydrogen airships return as fast, cheap, green cargo transports?

California startup H2 Clipper wants to bring back hydrogen-filled airships, claiming they can unlock completely green intercontinental cargo operations carrying 8-10 times the payload of any cargo plane over 6,000 miles, at a quarter of the price.Conti… Continue reading Could hydrogen airships return as fast, cheap, green cargo transports?

Squirrel-cheeked liquid H2 airliner will take you anywhere in two hops

Long-haul aviation presents a tough challenge for decarbonization, but a group of 100 aerospace experts working on the UK government’s FlyZero project says 279-seat liquid hydrogen airliners will connect any two points on the globe with just one stop.C… Continue reading Squirrel-cheeked liquid H2 airliner will take you anywhere in two hops
