Ballard to Supply 8 MW of Fuel Cell Engines to Stadler for Californian Passenger Rail

VANCOUVER, BC, Dec. 9, 2024 /CNW/ - Ballard Power Systems (NASDAQ: BLDP) (TSX: BLDP) today announced the signing of a multi-year supply agreement with Stadler US ("Stadler"; www.stadlerrail.com) to supply 8 megawatts of FCmove^®-HD+ fuel cell engines to power trains for the California Department of Transportation (Caltrans).

The supply of the FCmove^®-HD+ engines will be integrated into Stadler's line of zero-emission passenger trains, the FLIRT H₂.

The order builds on over three years of joint 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.

'We are thrilled to deepen our partnership with Stadler and support their work with Caltrans to decarbonize commuter rail transportation in California," said Randy MacEwen, Ballard CEO. "This order grows our footprint in the rail market and validates the value proposition for Ballard fuel cell engines to power passenger rail in regions lacking catenary wire infrastructure. Fuel cells offer a zero-emission replacement for diesel engines, with comparable payload, range, reliability, and refueling times," Mr. MacEwen concluded.

Martin Ritter, CEO of Stadler US commented, "Stadler is looking forward to working with Ballard and Caltrans to provide leading zero-emission trains to California and support the advancement of their zero-emission goals. The FLIRT H₂ train can replace diesel trains on non-electrified or partially electrified lines for emission-free passenger transport avoiding the investment in costly overhead catenary lines electrification would otherwise require."
