Hydrogen-powered

Segway-Ninebot has rather sensationally announced that it's building a hydrogen fuel cell sportsbike – and boy does this thing look like it glitched its way out of Cyberpunk 2077, complete with a highly improbable steering design and an amazing price.

Hydrogen commercial vehicle conversion company ULEMCo and industry partners have agreed the design of a new fuel cell rapid response ambulance prototype that's destined to hit the streets of London later this year.

Ten times the energy density of a lithium battery, in a simple magnesium-based paste that can be refilled at a pump or changed out in cartridges. Fraunhofer's Powerpaste offers a safe, convenient, high-density way to store, transport and use H2 energy.

With the move towards electric aviation comes new opportunities to explore what a powertrain looks like, and Airbus is experimenting with a new design that builds entire hydrogen propulsion units, tanks and all, into detachable pods along the wings.

Spanish company Quaternium has destroyed its own record for gasoline-electric drone endurance with a 10-hour, 14-minute flight. But how does that stack up against hydrogen and batteries, and what are the implications for the emerging eVTOL market?

VTOL (vertical take-off and landing) drones are quite versatile, as they combine the vertical flight of a helicopter with the efficient forward flight of a fixed-wing airplane. This one features an extended range, thanks to a fuel cell power system.

ZeroAvia says it completed the world's first hydrogen-fuel-cell powered flight of a commercial-grade aircraft when a modified Piper M-class six-seater plane took off from its facility in England, and completed a full-pattern circuit before landing.

Hydrogen is on the rise as the zero-emissions aviation fuel of the future, and LA-based fuel logistics startup Universal Hydrogen is partnering with electric aviation specialists Magnix to develop a 40-seat hydrogen-electric airliner for 2024.

Nemesis Yachts has put forward a blue-sky vision for a super-fast, hydrogen-powered, autonomous luxury catamaran that can rise out of the water on hydrofoils to achieve crazy speeds over 50 knots. Oh, and you can swap this 300-footer's cabins out.

California's Hyperion has released images, video and details on its wild-looking XP-1 hydrogen supercar, the first fuel cell performance car. Forget the Lucid Air's 517-mile range, this electric beast will go more than 1,000 miles on a tank of H2.

Progress hasn't come as quickly as expected, but Skai remains committed to pioneering liquid hydrogen as a power source for its ultra-long range eVTOL air taxis, which will travel vastly longer distances than anything with a lithium battery system.

The first 10 units of Hyundai's hydrogen-powered Xcient Fuel Cell – the world's first heavy duty fuel-cell-powered truck – have rolled off the production line and are on their way to Switzerland, with 40 more to follow later this year.
