Hydrogen-powered
-
A nanoporous material that holds hydrogen at twice the density of cryogenic liquid H2 could address the challenges of large-scale liquid and gas storage that have held this clean fuel back.
-
Yamaha previously announced it would show a prototype hydrogen outboard at the 2024 Miami Boat Show. Instead of simply revealing the motor, it's installed it on a prototype boat complete with fuel delivery system. Testing will begin this year.
-
Transporting goods by inland waterways can be a dirty business, but an EU-backed project is looking to clean up its act – launching a container vessel powered by green hydrogen on a major cargo route between the Netherlands and Germany.
-
ZeroAvia is working with San Francisco startup Verne to bring an even more energy-dense form of hydrogen to the clean aviation space. Cryo-compressed H2 could reduce costs, speed up fueling, and unlock 40% more flight range than cryogenic liquid H2.
-
MIT's Electric Vehicle Team has taken to the racetrack with a Ducati 900SS that's been gutted and converted into a hydrogen fuel cell motorcycle, hoping to start collecting a few fossil-fuelled scalps. It's also open-sourcing the design for others.
-
The Sirius Jet will fly up to 1,150 miles (1,851 km) at speeds up to 323 mph (520 km/h) on a clean liquid-hydrogen powertrain. It'll rise vertically off a pad thanks to a deflected vectored thrust system using 20 smallish electric ducted fans.
-
Kawasaki is doing some fascinating work toward decarbonizing motorcycles. After launching the world's first hybrid streetbike in the Ninja 7 Hybrid, it's now built a supercharged, zero-emissions, hydrogen-powered Ninja H2 SX. An H2 H2, if you will.
-
Yamaha has become an early leader in hydrogen engine development for autos, and now it's looking to launch its hydrogen-combustion program into the water. Its new hydrogen outboard prototype will debut at the 2024 Miami International Boat Show.
-
AVL had a pretty good day earlier this month, when it confirmed its prototype 2.0-liter turbo hydrogen race engine could generate over 200 hp-per-liter. AVL uses a water-injection system alongside its turbo to moderate combustion for more power.
-
Launched in February of this year, BMWs iX5 pilot fleet of hydrogen-powered cars has been getting field tested in countries around the world. Most recently, the passenger car got put through its paces in the punishing conditions of the UAE.
-
HySE, a Japanese research association that counts Honda, Toyota and Yamaha as members, is preparing a hydrogen ICE-powered side-by-side for Dakar 2024. Its supercharged X1 off-roader will tackle part of the grueling event for hydrogen engine R&D.
-
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.
