**Ballard Power Systems has announced the signing of a multi-year supply agreement with [Stadler](https://stadlerrail.com/en/) US to supply 8 megawatts of [FCmove®-HD+ ](https://www.ballard.com/wp-content/uploads/2024/11/SPC5111379-0D.pdf)fuel cell engines to power trains for the California Department of Transportation (Caltrans). The supply of the 100kW modules will be integrated into Stadler’s line of zero-emission passenger trains, the FLIRT H2.**

The order builds on over three years of collaboration, including the successful integration of Ballard fuel cell engines into the FLIRT H2, which became the first Federal Railroad Administration (FRA) compliant hydrogen fuel cell-powered passenger train demonstrated in the United States.

The order supports Caltrans’ purchase of 10 FLIRT H2 trains, with an option for an additional 19 trains, to strengthen the state’s zero-emission passenger rail capabilities.

The Stadler Flirt H2 was originally unveiled to the public at the INNOTRANS 2022 industry tradeshow in Berlin, Germany, and has since successfully completed rigorous durability and reliability capabilities testing in Europe and the U.S. 

In March 2024 the zero-emission train [set a Guinness world record](https://blog.ballard.com/rail/stadler-flirt-h2-zero-emission-train-breaks-guinness-world-record) for the furthest distance recorded by a hydrogen fuel cell passenger train without stopping to refuel - completing a route of 2,803km (1,742 miles) in 46 hours.

The Flirt H2 is driven by six Ballard FCmove®-HD+ fuel cell engines, delivering a combined power capacity of 600kW. The train seats 108 passengers, and has a maximum speed of 130 km/h (79 mph).
