Doosan’s 2025 Fuel Cell Pivot: Inside the High-Stakes Shift to SOFC and New Markets

Industry Adoption: Doosan’s Fuel Cell Strategy Evolves from PAFC Dominance to SOFC Diversification

Between 2021 and 2024, Doosan Fuel Cell cemented its status as a market leader by scaling its proprietary Phosphoric Acid Fuel Cell (PAFC) technology. The company’s commercial dominance was epitomized by the 50 MW Shinincheon Bitdream Fuel Cell Power Plant, the world’s largest of its kind, and a consistent order book exceeding KRW 1 trillion for three consecutive years. However, this period also revealed the strategic imperative to diversify. Recognizing the limitations of relying on a single technology and its domestic market, Doosan initiated a multi-pronged expansion, forging partnerships to develop Solid Oxide Fuel Cells (SOFC) with Ceres Power for high-efficiency stationary and maritime use, and Proton Exchange Membrane (PEMFC) systems with Ballard Power for the mobility sector. This strategy extended to niche applications, with a KRW 27 billion ($22.4 million) investment in its subsidiary, Doosan Mobility Innovation (DMI), to develop hydrogen-powered logistics drones, signaling a clear intent to move beyond large-scale power generation.

The year 2025 marks a critical inflection point where this strategy has transitioned from development to high-stakes execution. The most significant development is Doosan’s aggressive commercial pivot to SOFC technology, culminating in the July 2025 commencement of mass production at its new 50MW factory in Jeollabuk-do, South Korea. This facility, the world’s first for Ceres’ metal-supported SOFCs, is squarely aimed at lucrative, high-growth markets like AI data centers, where SOFC’s 60%+ electrical efficiency offers a compelling value proposition. This forward momentum, however, is contrasted by a harsh market reality. In a major setback, Doosan terminated three PAFC supply contracts in April 2025, totaling ₩818 billion (approx. $560 million), citing project delays and financing challenges. This event highlights the volatility and bankability risks inherent in the large-scale hydrogen project landscape and starkly validates Doosan’s strategic decision to diversify. The variety of new initiatives—from biogas-fed fuel cells with Korea Western Power to maritime applications with Shell—demonstrates a sophisticated strategy to de-risk and capture a broader range of commercial opportunities across the energy value chain.

Investment Analysis: Funding Doosan’s Fuel Cell Ambitions

Doosan Fuel Cell’s strategic evolution is underpinned by a series of targeted investments designed to build capacity, fund new technology, and consolidate its market position. The company’s financial data reveals a classic growth-stage profile: high capital expenditure and a focus on capturing market share, currently operating at a net loss as it invests heavily in its future. With a trailing twelve-month net income of -₩18.12 billion and a negative profit margin of -4.33% as of July 2025, the pressure to successfully commercialize its new SOFC products is immense. Capital has been raised and deployed to expand its established PAFC business while simultaneously building out entirely new production lines for next-generation technologies. A pre-IPO funding round for its US unit HyAxiom further illustrates the strategy to attract external capital to fuel global ambitions, separate from its core balance sheet. These financial maneuvers are critical to funding the transition from a regional PAFC leader to a global, multi-technology clean energy provider.

Geographic Analysis: Doosan’s Fuel Cell Footprint from Korea to Global Markets

Between 2021 and 2024, Doosan’s commercial activity was overwhelmingly centered on its home market of South Korea. This domestic dominance was built on large-scale PAFC deployments like the Shinincheon power plant, the Iksan factory expansion, and a dense network of local partnerships (KOSPO, KHNP, SK Energy). Early forays into international markets were cautious but strategic, highlighted by a 1.8 MW fuel cell export to Foshan, China, and a more substantial 105 MW supply agreement with China’s ZKRG Smart Energy. The United States served as a base for technology development and niche market entry via its subsidiary HyAxiom, which demonstrated hydrogen drones with SoCalGas.

From 2025 onwards, Doosan’s geographic strategy has become markedly more global and integrated. While South Korea remains the core manufacturing and deployment hub for its new SOFC technology (Jeollabuk-do factory, Samchully MOU), the ecosystem supporting this pivot is international. The critical SOFC technology is licensed from the UK-based Ceres Power, and a key supply chain component is sourced from Alleima in Sweden. The letter of intent with Shell, a global energy major, for maritime applications intrinsically targets a global market. Furthermore, the partnership with Tyczka Hydrogen GmbH via its subsidiary Accelera signals a clear strategic push into the highly regulated and lucrative German and broader European markets. This evolution shows a shift from a strategy of domestic leadership and opportunistic exports to building a truly global and resilient operational footprint.

Technology Maturity: Tracking Doosan’s Fuel Cell Portfolio from Commercial to Pilot

From 2021 to 2024, Doosan’s technology portfolio was led by its fully commercial and scaling Phosphoric Acid Fuel Cell (PAFC) technology. With a 275 MW production capacity and a flagship 50 MW power plant, PAFC was a mature, bankable product generating recurring service revenue. During this period, Solid Oxide Fuel Cell (SOFC) technology was in an advanced demonstration phase; the Ceres Power partnership was active, culminating in a world-first maritime environmental test pass in March 2024, a key validation milestone. Proton Exchange Membrane (PEMFC) technology for mobility was in an earlier development stage, formalized by the 2022 partnership with Ballard Power.

The period from 2025 to today represents a dramatic shift in technological maturity. The most significant event is the graduation of SOFC technology from demonstration to commercial-scale production. The July 2025 launch of the 50MW mass production factory is the ultimate validation point, moving SOFCs from a future promise to a present-day commercial product, with first sales anticipated by year-end. PAFC technology, while still commercial, is showing signs of market headwinds with major contract cancellations. Meanwhile, PEMFC is advancing from development toward its first commercial application, with Doosan’s plan to launch hydrogen buses in Korea by mid-2025. Finally, new concepts are entering the demonstration phase, such as the development of a biogas-fed fuel cell with Korea Western Power, showing a continuous pipeline of innovation.

2025 Forward Outlook: Key Signals for Doosan’s Fuel Cell Trajectory

The data from 2025 paints a clear picture: Doosan Fuel Cell is in a pivotal, high-risk, high-reward transition. While its legacy PAFC business faces headwinds, the company has placed a decisive bet on the commercialization of higher-efficiency SOFC technology. Understanding these complex shifts requires detailed, real-time tracking of commercial activities, a challenge for any strategy team seeking to navigate the energy transition. For the year ahead, market actors should watch three critical signals to gauge the success of this pivot.

First is the execution of initial SOFC sales. Doosan anticipates the first commercial sales from its new factory before the end of 2025. The key will be to identify the buyers and applications. Securing contracts for data centers or high-value commercial buildings would strongly validate its market thesis. Second, watch for concrete progress in the maritime sector. The August 2025 letter of intent with Shell and KSOE is a powerful signal, but it must translate into a firm joint development agreement or a funded pilot project to maintain momentum. This will be the clearest indicator of its potential to capture a share of the massive marine decarbonization market. Finally, financial performance will be paramount. With significant capital already deployed, the market will look for any signs of a path to profitability, driven by new high-margin service agreements like the recent ₩411.8 billion LTSA and revenue from the new SOFC business line. The ability to manage cash flow and demonstrate commercial traction in these new areas will determine whether Doosan’s bold strategic pivot succeeds.
