Hydrogen-powered
-
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.
-
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.
-
Piasecki Aircraft is working on a full-size winged helicopter running HyPoint's air-cooled hydrogen fuel cell system – but to test that powertrain, it's converting an ultralight compound chopper for the world's first manned H2 helicopter flight.

A Geneva concept car without a Geneva Motor Show, the Alpine A4810 is a look at an absolutely menacing hydrogen supercar. Its rear-end looks like an intergalactic fighter jet, contributing to an absolutely futuristic vision for supercar supremacy.
-
The Extreme E electric off-road race series is either going to expand to include an Extreme H hydrogen-powered zero-emissions race series, or flat-out switch to hydrogen-only from 2024. It's quite an announcement from a one-year-old championship.
-
Hydrogen combustion engines are inefficient, costly to maintain and worse for the environment than fuel cell or battery powertrains. But they're also noisy and fun, so automakers are starting to pitch them as a greener option for die-hard motorheads.
-
Developing a zero-emissions fuel-cell off-roader to compete in Baja 1000 is hard enough. But using cryogenic liquid hydrogen that stores at -423 ºF as fuel? That's just lunacy. Lunacy reigns at SCG, where a cryo-hydrogen Baja Boot is in development.
-
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.
-
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.
-
Combining two forms of sustainable energy into one, Swiss Sustainable Yachts' Aquon One catamaran harnesses solar energy to create its own hydrogen, powering a fuel cell drive to potentially limitless autonomy.
-
French company Gaussin is pushing hard on hydrogen-based long-haul trucking, and to prove it's ready to bang with the big boys, it's taking the first hydrogen race truck to the Dakar rally in Saudi Arabia next year for the ultimate torture test.
-
Back in February, ULEMCo and industry partners announced plans to design an electric rapid response ambulance powered by batteries and hydrogen fuel cells. Now, the working prototype has driven into Glasgow for display at the COP26 climate summit.
