Hydrogen-fueled trucks can keep thousands of tons of carbon out of the air every year. A prototype rescue truck from the US Department of Energy shows just how viable the clean-burning haulers are becoming – by bagging a new world record.

The first and largest of its kind: a 30 MW, pure-hydrogen electrical generator called the Jupiter One just completed its first successful full-system test.

The Alpine Alpenglow is back, this time equipped with an all-new "Hy6" twin-turbo V6 engine developed from the ground up to run on hydrogen. The Hy6 doubles the power of the last Alpenglow, delivering true supercar performance and rumble.

The Pioneer 25 marks a momentous step in the world of motorsports as it passed the mandatory FIA crash tests. Developed solely for Extreme H, the world’s first hydrogen-powered motorsport, the car has a top speed of 200 km/h (124 mph).

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing but fresh water out of the tailpipe.

As we move to a zero-carbon transport future, Kawasaki is testing the waters of greener and cleaner motorcycle technologies. Following the reveal of a hydrogen-powered Ninja H2 SX last year, the prototype has made its first public appearance in Japan.

One of the world's largest engines becomes a clean generator. Originally designed to burn diesel, dual-fuel, or gasoline for tankers and container ships, the Wärtsilä 31 marine engine gets a new life generating clean, renewable electricity.

The latest hydrogen ICE to rumble to life was born with a special mission: claim a land speed record or two for the emerging hydrogen-combustion space. A University of Bath team has successfully gotten its hydrogen-burning prototype working.

After a hell-raising concept iteration, Alpine's hydrogen combustion fire-and-ice Alpenglow supercar is finally prepped and revved to take the track. It'll make its dynamic debut next month at the Spa-Francorchamps 6 Hours endurance event in Belgium.

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.

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.
