Hydrogen-powered

Back in 2019 we heard about the sleek electric Bubble Taxi, a five-seat enclosed hydrofoil created by French manufacturer SeaBubbles. The company has now announced a bigger and faster model, simply called the SeaBubble.

Four years after embarking on a two-year operational trial run in Germany, a bunch of Coradia iLint hydrogen fuel-cell trains have entered passenger service along a 100% hydrogen route in Lower Saxony.

H2 Clipper says large electric airships lifted and powered by green hydrogen stand ready to transport massive cargo loads over enormous distances much faster than cargo ships, and with zero emissions. But can they overcome the obvious obstacles?

UK startup Viritech has launched its gorgeous Pininfarina-penned Apricale hypercar at Goodwood, and dropped some impressive specifications to go with it. This hydrogen-powered monster will break both the 1,000-horsepower and 1-hp-per-kg barriers.

The Celera 500L is a truly remarkable design. Otto Aviation says its odd shape delivers an astonishing 59% reduction in drag, so it can cruise as fast as a small jet while using 80% less fuel. Now, Otto and ZeroAvia are giving it a clean powertrain.

A Norwegian team has claimed a world-first, running a gas turbine on 100 percent hydrogen. The modifications made to the turbine, fuel systems and the natural gas infrastructure, could be used to convert other turbines to zero emissions.

Toyota wants hydrogen to power entire cities in Japan, and over the weekend it presented prototype H2 canisters it's developed with its subsidiary Woven Planet. These hydrogen tubes will twist-lock into sockets in vehicles, homes, and other devices.

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.
