Hydrogen-powered

Liquid hydrogen is a giant pain to handle, but it's one of the few technologies with a genuine chance of decarbonizing long-range flight. So it's huge news for clean aviation that H2Fly has now landed the word's first piloted liquid hydrogen flight.

A student team from TU Delft presented the latest Eco-Runner in May, a hydrogen-powered city car concept designed to be more than a hundred times more fuel-efficient than modern fossil-fuel vehicles. Now the car has set a Guinness distance record.

French transport multinational Alstom debuted the world's first hydrogen fuel-cell passenger train back in 2016, which went into service in Germany last year. Now the Coradia iLint is rolling down the track in North America for the first time.

Tevva has been working to ease the burden of carbon reductions on fleet operators. In January, it began production of its battery-powered medium-duty electric truck. Now it's improved the efficiency of its regenerative braking system by four times.

The blended-wing Natilus Kona aircraft, which is now flying in quarter-scale testing in California, is set to have a zero-emissions variant thanks to a partnership with Zeroavia, which will provide a 600 kW hydrogen-electric powertrain option.

Alpine's street cars might not be known for outrageous design, but this Alpenglow concept would grab its share of eyeballs even parked next to a Delage D12, an Aston Martin Valkyrie and a Bugatti Bolide. Plus, it's noisy. Plus, it's zero-emissions.

Compared to the electric camper vans, a hydrogen fuel cell RV could immediately boost driving range to something practical. First Hydrogen explores just such a concept, showing its next-generation fuel cell vehicle as an all-terrain camper van.

The world's largest rail vehicle manufacturer has rolled out a zero-emissions train running on hydrogen fuel cells with a supercapacitor buffer. The four-car train is capable of 100 mph (160 km/h), making it the fastest hydrogen train to date.

ZeroAvia's 19-seat Dornier 228 has taken its first test flight in the UK. It's a testbed for the company's clean aviation technology, using a zero-emissions hydrogen-electric powertrain that's slated for certification and commercial flights by 2025.

France's H3 Dynamics has presented a self-contained hydrogen propulsion pod for drones and airplanes, delivering huge range and endurance figures without heavy batteries. It mirrors the approach Airbus and others are taking with commercial airliners.

Toyota forges ahead with its multi-pronged sustainable vehicle strategy. The Hilux Revo BEV concept makes an appearance just days after the company announced a fuel cell Hilux prototype. Will the future of the rugged pickup be BEV, FCEV or both?

Hydrogen combustion engines offer a chance to go (nearly) green without losing the sound, feel and excitement of driving a noisy, mechanical, piston-driven engine. Toyota has been racing one, and now it's evaluating a prototype Corolla for the street.
