When the world’s first hydrogen-powered off-road racing series launched in Qiddiya City, Saudi Arabia, it wasn’t just a milestone for motorsport, it was a defining moment for hydrogen technology. Extreme H marks the start of a new era where clean, green hydrogen power takes centre stage in one of the toughest, most unforgiving environments imaginable.
For GeoPura, the event represented the culmination of years of collaboration with Extreme H, Siemens, and Siemens Energy, and a powerful demonstration that hydrogen is safe, reliable, and ready to perform under pressure.
Pushing hydrogen to the limits
Motorsport has long been a testing ground for innovation. From carbon fibre to regenerative braking, many of today’s technologies were proven first on the track. Now, hydrogen is taking its turn in the spotlight.
Extreme H’s debut in Qiddiya City wasn’t just about racing, it was about proving that hydrogen technology can operate safely in extreme heat, high-performance conditions, and remote environments. With track temperatures soaring above 40°C, every system, from refuelling infrastructure to onboard fuel cells, was put to the ultimate test.
And that’s exactly what the Qiddiya race achieved, showing that hydrogen can be powerful, efficient, and safe when managed with precision and expertise.
Safety at the core
Transitioning to hydrogen meant starting with safety. GeoPura was brought in as a core technical partner to support the design, testing, and operational deployment of hydrogen systems across the series. Our team worked closely with Siemens and the FIA, the global governing body of motorsport, to validate the car’s hydrogen systems and ensure they met stringent international safety standards.
Using computational fluid dynamics (CFD) modelling in partnership with Siemens, GeoPura simulated a range of potential scenarios — from hydrogen leaks to crash impacts — to predict how the fuel would behave and confirm that the vehicle systems were safe to race.
As GeoPura CTO, Theo Elmer, explained:
“We wanted to understand exactly what would happen to hydrogen in a worst-case scenario. Siemens’ Simcenter CFD software allowed us to model that very accurately. Hydrogen, like any fuel, needs to be correctly managed and maintained – when it is, it’s perfectly safe.”
These insights provided the Extreme H engineering team with the confidence to race at full performance, knowing that every aspect of the hydrogen system was designed with safety at its core.
From race track to real world
The Qiddiya City launch showed the world what’s possible when innovation meets collaboration. Hydrogen is not just a future concept — it’s a working, proven technology that can deliver clean power safely and efficiently in the most demanding conditions.
Theo Elmer stated: “It was incredible to see the technology we’ve helped develop come to life on the track in Qiddiya. The conditions were extreme, the heat, the speed, the pressure, but that’s exactly what makes this project so exciting. Seeing the race cars perform safely and reliably in such an environment was a real validation of the work our teams have done. Being on site to provide technical support and witness hydrogen power in action was a proud moment for everyone involved.”
At GeoPura, our mission is to accelerate the transition to clean energy by proving that hydrogen can work in real-world applications — from construction and data centres to film production, transport, and now, elite motor sport.
