PEM Fuel Cell Rail Dominance: Ballard’s 8 MW Stadler Deal, CPKC Expansion, and 10+ Global Projects (2021 to 2026)

Proton Exchange Membrane (PEM) fuel cells are the definitive technology for decarbonizing global rail networks, offering high power density and the operational flexibility required to replace diesel engines. The market has matured from initial pilot programs in North America and Europe into a phase of global commercial scaling and intense competition. While incumbents like Ballard Power Systems and Accelera by Cummins secured early leadership, the period from 2025 has been defined by the strategic entry of new players into high-growth Asian markets, signaling a new chapter in the sector’s expansion. This technology’s versatility is also being demonstrated in other demanding sectors, from the shipping and maritime industry to providing resilient power for data centers.

Ballard and Accelera Cement Market Leadership with 10+ Rail Projects

From 2021 to 2024, Ballard Power Systems and Accelera by Cummins established a market duopoly by securing foundational projects in North America and Europe, which have now progressed to expansion and replication phases from 2025 onwards.

Ballard’s North American and European Foundation

• Ballard’s early projects with Canadian Pacific Kansas City (CPKC), Stadler Rail for the San Bernardino County Transportation Authority (SBCTA), and PESA in Poland established the company as a leader in both retrofitting freight locomotives and powering new-build passenger trains. The SBCTA project alone represents an 8 MW order for fuel cell engines.
• These initial deployments were critical for proving the technology’s viability and have resulted in follow-on orders, such as the April 2025 announcement that CPKC would expand its Ballard-powered hydrogen locomotive fleet.

Accelera’s Passenger Rail Focus

• Accelera by Cummins, formerly Cummins New Power, focused on the passenger rail segment, notably through its partnership with Alstom to power the world’s first fleet of hydrogen passenger trains in Germany.
• Additional projects, including powering a locomotive in Austria and North America’s first green hydrogen-powered passenger train, solidified Accelera’s position in the commuter and intercity rail market, demonstrating the effectiveness of its PEM fuel cell systems for high-traffic routes.

2025-2026 Expansion and Validation

• The period from 2025 saw validation of these initial projects. The successful operation of early fleets led to expansions like the one at CPKC and the official launch of India’s first hydrogen-powered train in July 2026, which utilizes eight of Ballard’s 100 k W FCmove™-HD+ modules.
• This phase demonstrates a market shift from one-off pilots to fleet-level commitments, underscoring customer confidence in the technology’s performance and reliability, with Ballard-powered trains having accumulated over 500, 000 km of service.

Partnership Analysis: New Alliances Challenge Ballard’s Existing Foothold

While Ballard’s long-term partnerships with rail OEMs like Stadler and operators like CPKC remain central, new strategic alliances formed in 2025, particularly in Asia, signal a shift in the competitive landscape.

The Incumbent Alliances: Ballard & Accelera

• Ballard’s strategy relies on deep integration with rail manufacturers such as Stadler and PESA, alongside direct collaboration with major rail operators like CPKC. This approach creates high barriers to entry through proven technology and established service relationships.

Horizon Fuel Cell’s Strategic Entry into India

• Horizon Fuel Cell Technologies’ exclusive 10-year partnership with India’s state-owned Bharat Heavy Electricals Limited (BHEL), signed in September 2025, is a significant maneuver to capture the vast Indian Railways decarbonization market. This alliance directly challenges Ballard’s first-mover project in the country.

HDF Energy’s Diversified Heavy-Duty Approach

• HDF Energy is pursuing a broader strategy across heavy-duty transport. Its partnership with ABB in December 2025 to develop high-power fuel cells for ships and a $500 million green hydrogen initiative in Vietnam create a strong technological and logistical base that can be leveraged into the rail sector, representing a new competitive vector.

Geographic Shift: North America & Europe Pilots Give Way to Asian Market Expansion

The PEM fuel cell rail market is undergoing a significant geographic pivot, moving from initial high-profile pilots in North America and Europe between 2021 and 2024 to large-scale commercial deployments and new partnerships targeting the massive rail networks in Asia from 2025 onwards.

2021-2024: The North American & European Proving Grounds

• Early market leadership was established in North America through Ballard’s projects with CPKC in Canada and the U.S. and the Stadler-built train in California. In Europe, Accelera’s work with Alstom in Germany and Ballard’s project with PESA in Poland served as critical proving grounds.

2025-2026: The Race for Asia

• From 2025, the competitive focus shifted decisively to Asia. India became a key battleground, with Ballard powering the country’s first hydrogen trains while Horizon Fuel Cell formed a strategic alliance with state-owned BHEL to pursue future large-scale projects.
• Other significant activity includes HDF Energy’s $500 million green hydrogen initiative in Vietnam and a strategic partnership in Indonesia, highlighting Southeast Asia’s emergence as the next major growth frontier for hydrogen-powered transportation.
• Hyundai Rotem’s continued development and promotion of its hydrogen fuel cell tram, showcased in February 2025, underscores South Korea’s domestic focus and its potential as a future technology exporter in the region.

Hydrogen Fuel Cell Market Set for 320% Growth by 2032
The overall Hydrogen Fuel Cell Market, which includes Proton Exchange Membrane Fuel Cells (PEMFC) and transportation applications, is forecast to surge from $4.35 billion in 2024 to $18.24 billion by 2032, driven by a robust 19.64% CAGR. This rapid expansion signifies a major opportunity across all segments, including the burgeoning rail sector.

Scenario Modelling: Will Ballard’s First-Mover Advantage Hold in 2026?

The critical test for 2026 and beyond is whether Ballard’s established technological lead and incumbency with major operators like CPKC can defend its market share against aggressive, regionally-focused partnerships like the Horizon/BHEL alliance in India.

• If this happens: Watch for announcements from Horizon and BHEL regarding a follow-on order or a large-scale fleet deployment plan for Indian Railways, potentially leveraging local manufacturing incentives to create a significant cost advantage.
• Watch this: The key counter-signal would be an announcement from Ballard deepening its partnership with its initial Indian client or establishing a local manufacturing presence to neutralize the “made in India” advantage of the Horizon/BHEL partnership.
• These could be happening: In this competitive environment, Ballard may be forced to adjust its pricing strategy in competitive tenders, impacting margins. Alternatively, the company could pivot to focus on premium applications where its deep experience with heavy-haul freight provides a defensible technological moat that new entrants cannot easily replicate.
