Hydrogen-powered

Universal Hydrogen has signed letters of intent with three airlines to convert regional airliners to run on green hydrogen. The company is developing conversion kits that accept interchangeable hydrogen modules that work like recyclable coffee pods.

German clean aviation companies H2Fly and Deutsche Aircraft are joining forces to develop a hydrogen-fuel-cell-powered airliner capable of carrying 40 people, with a demonstration aircraft set to take its first flights in 2025.

Despite an abrupt and unscheduled ending to its six-seater test program, hydrogen aviation pioneer ZeroAvia is ramping up development of the largest fuel cell-powered aircraft to date – a pair of 19-seaters – and is preparing for something much bigger.

French company Hopium has wasted no time getting a prototype up and running. The company announced its intentions to build high-performance hydrogen cars in October 2020, and has now shown video of its 200-km/h Alpha 0 prototype on a test track.

The Land Rover Defender is one of the world's great explorers, a natural candidate for a zero-emissions powertrain. Land Rover thinks the right fit might be a hydrogen fuel cell drive that stands up to driver demands while leaving behind only water.

Switch Maritime says its Sea Change ferry is nearly built and ready to work in the San Francisco Bay in Q3 this year. Powered by compressed hydrogen gas running through a fuel cell, it'll be the first of its kind, running for two days on a tank.

Aquarius Engines has developed a tiny hydrogen engine it hopes can serve as a range-extender in electric vehicles and as a standalone micro-generator. Weighing just 22 lb, the small, simple engine uses a single moving piston to develop power.

Suggestively-named UK company Viritech has announced that it's making an altogether different kind of male enhancement supplement than we'd have expected, in the form of a hydrogen-powered hypercar called the Apricale.

Airbus is working on a number of hydrogen-powered aircraft, and it's just found a new angle on cryogenic liquid H2 fuel: using it to supercool the powertrain down to superconducting temperatures, possibly unlocking huge weight and efficiency savings.

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.
