4-legged hydrogen-powered robot you can actually ride

CORLEO isn’t your typical off-road vehicle. Instead of wheels, it has four robotic legs that move independently, allowing it to handle uneven ground like rocks, grass and steep inclines. Kawasaki says the design was inspired by the skeletal structure of lions. The name CORLEO is derived from Cor Leonis, the brightest star in the constellation Leo. Riders mount it like they would a horse, but instead of gripping handlebars or using pedals, you control CORLEO with your body. Lean forward, and it moves ahead. Shift your weight to the side, and it adjusts its steps accordingly.

CORLEO is also environmentally friendly. It uses a battery paired with a 150cc hydrogen engine. The hydrogen engine generates electricity, which is stored in the battery. Kawasaki has been pushing hydrogen-powered vehicles for years, and CORLEO is their latest effort to combine sustainability with innovation.

An Engine That Burns WATER

AVL RACETECH, the motorsport division of AVL, unveiled in 2022 a groundbreaking prototype of a hydrogen-powered internal combustion engine. This 2-liter turbocharged engine is fueled by hydrogen and incorporates advanced water injection technology, pushing the boundaries of performance to new heights. 

The release of the engine marked the first time AVL RACETECH designed and constructed a racing engine entirely in-house, showcasing their commitment to innovation in motorsport technology.

Changing the way hydrogen engines operate

AVL RACETECH’s hydrogen internal combustion engine release three years ago was designed to outperform other hydrogen engines, which typically operate with lean-burn, resulting in lower performance. 

Unlike those traditional hydrogen engines, this engine uses only a slight lean-burn, achieving an impressive 150 kW per liter of output. This level of performance puts the 2-liter turbocharged hydrogen engine on par with today’s high-performance racing engines that are close to production models.     READ MORE...

Bosch & the Hydrogen Engine in 2024

The German automaker Bosch announced its plan to launch its first hydrogen engine for trucks and construction equipment in 2024, which will be part of its existing fuel cell and battery-electric offerings.

Despite the gains made by EVs over the past decade, hydrogen is still a hot topic, with a handful of automakers that have developed and even fielded production hydrogen fuel-cell models. You can probably guess right away just which automakers we’re talking about: Toyota, BMW, and Honda.

Despite the huge success of electric vehicles (EVs) over the past decade, automakers such as BMW, Toyota, and Honda still see hydrogen as a potential business in the future. As hydrogen engine technology’s popularity increases, these manufacturers have responded with innovations in the production of hydrogen fuel-cell vehicles.

Besides heavily investing in EVs, they have also been preparing for a time when all sizes of hydrogen fuel-cell cars would coexist with electric vehicles and be a significant part of the zero-emission vehicle landscape.

However, in that bright future, hydrogen models could come in more forms than just fuel-cell cars. Recently, Bosch provided more details about their ideas for a hydrogen engine, an alternative method of using hydrogen as a fuel for automobiles.   READ MORE...

Next Generation of Hydrogen Engines

Hydrogen-based technology is not only setting standards on the racetrack and in the automotive industry in general, it is also present in other areas of human activity where diesel and gasoline internal combustion engines have dominated for decades, such as the construction industry. This is the case of the B6.7H hydrogen engine developed by Cummins, which will be unveiled at the Intermat exhibition in Paris from April 24 to 27 this year.

Intermat is an international trade show that showcases, among other things, the latest advances in technological solutions for the construction industry. Cummins will use this platform to showcase this new engine, which can seamlessly replace diesel and gasoline engines currently used in a variety of construction equipment.

Cummins New Hydrogen Engine
This new design of the B6.7 engine has a displacement of 15 liters and can operate on a variety of clean fuels such as biodiesel, hydrogen and natural gas. One of its great advantages is that it requires no adaptations and can be easily connected to the equipment and accessories that work with conventional engines: cooling system, transmission and hydraulic system. On the other hand, its maintenance is no more demanding than that of a traditional diesel engine.  READ MORE...
