Exploring Hydrogen Combustion Through Motorsport
The Hydrogen For Life conference in London last week showcased a forward-looking discussion on the future of hydrogen technology in motorsport. Bosch, Ferrari, and Alpine Racing, along with other key industry players, shared groundbreaking updates on their hydrogen race cars and how these advances could shape not only motorsport but the broader transportation industry.
One of the first keynote speeches was delivered by Lionel Martin, Bosch Engineering’s H2 engines and storage product manager. Martin focused on Bosch’s development of the Ligier JS2 RH2, a high-performance hydrogen combustion “race-ready” demonstrator. Powered by a 3.0-litre V6 gasoline engine converted to hydrogen, this vehicle represents the convergence of innovation and practicality.
Bosch’s Hydrogen Race Car Breakthrough
The JS2 RH2, revealed at the Centenary edition of Le Mans 24 Hours last year, has logged over 5,000 testing kilometers in just 18 months. Producing upward of 600 horsepower, the car has proven capable of maintaining track performance for 20–25 minutes per stint. Key to this progress is the seamless conversion of a gasoline engine to a hydrogen combustion system—a development Bosch sees as a stepping stone to larger applications.
Lionel Martin outlined Bosch’s future goals, including the incorporation of liquid hydrogen into motorsport, aligning with the FIA’s vision. “Liquid hydrogen is a massive challenge,” he remarked. “From onboard systems to logistics, it requires significant innovation, but it could be the key to unlocking hydrogen’s potential in high-powered racing applications.”
While development on the JS2 RH2 has paused, Bosch remains committed to refining the next generation of hydrogen engines and vehicle storage systems.
Ferrari’s Pursuit of Hydrogen Combustion
Ferrari, renowned for its V12 engines and Formula 1 pedigree, brought a unique perspective to the table. Massimo Medda, Ferrari’s powertrain innovation manager, emphasized the company’s focus on hydrogen combustion as opposed to fuel cell technology. According to Medda, hydrogen’s ability to replicate the performance characteristics of traditional internal combustion engines (ICEs) has strong appeal for Ferrari, blending power and high-revving dynamics.
“Keeping the soul of combustion engines alive is at the core of our goals,” Medda stated. He explained that Ferrari has been exploring hydrogen options for years and believes its combustion technology aligns with emission regulations without sacrificing performance.
Still, Ferrari highlights the challenges hydrogen must overcome to expand its footprint. Beyond the racetrack, developing infrastructure for rapid hydrogen refueling and addressing tank efficiency are among the key hurdles they aim to solve.
Alpine Looks Ahead With Hydrogen V6 Development
Alpine Racing also presented its hydrogen innovation efforts at the conference, showcasing the Alpenglow Hy6, which debuted earlier this year at Le Mans. Their bespoke twin-turbo V6 with a cutting-edge combustion chamber design stemmed from lessons learned in Formula 1, marking another leap forward in hydrogen-fueled race cars.

Pierre-Jean Tardy, Alpine’s chief hydrogen engineer, expressed the company’s preference for liquid hydrogen as a racing fuel. He emphasized that its quicker refueling time and higher energy density make it a better fit for motorsport than gaseous hydrogen. However, like Ferrari, Alpine stressed the importance of reducing storage tank mass and establishing efficient distribution channels for long-term success.
Advancements in Hydrogen Combustion Technology
The advancements in internal combustion hydrogen engines discussed at the conference have the potential to reshape the approach to carbon-neutral motorsport. Key features include:
-
Engine Compatibility:
- Efficient adaptation of traditional gasoline engines to run on hydrogen.
- Retention of high power and RPM characteristics similar to traditional ICEs.
-
Performance Enhancements:
- Achieving over 600 horsepower in race cars such as the JS2 RH2.
- Potential for a 20% power boost through engine hardware optimization.
-
Fueling Innovations:
- Development of onboard systems for handling liquid hydrogen.
- Reduction in refueling times, suitable for competitive motorsport scenarios.
-
Emission Improvements:
- Hydrogen combustion aligns with carbon-neutral targets by eliminating CO2 emissions.

How Hydrogen Technology Applies Today and in the Future
Hydrogen’s application in motorsport offers a practical demonstration of its capabilities in high-demand environments. Racing innovations can be transferred to everyday use, particularly for industries relying on heavy-duty engines and high power outputs. Adapting these advancements for public transport, trucking, and energy generation could significantly reduce global emissions.
For example, the research into liquid hydrogen storage and refueling could pave the way for more viable and accessible hydrogen solutions for long-haul transportation fleets. Furthermore, converting existing gasoline engines to hydrogen could reduce dependency on fossil fuels without requiring immediate fleet overhauls.
Nevertheless, the road to hydrogen adoption is not without challenges. Developing a reliable hydrogen refueling infrastructure and efficient distribution remains critical for scaling beyond the racetrack. This transition will also depend on collaboration between manufacturers, legislators, and researchers to ensure affordable and sustainable hydrogen production.
The innovations presented at the Hydrogen For Life conference underscore hydrogen’s promise as a versatile and powerful energy source. By fusing competitive motorsport with cutting-edge engineering, the industry showcases how hydrogen can meet today’s challenges while fueling a cleaner energy future. Whether on the racetrack or in everyday vehicles, these advancements are paving the way for new sustainable possibilities.
