Doosan SOFC Pivot: $974 M in Cancellations, a 50 MW Factory Launch, and KEPCO’s 20-Year PPA (2025)

Execution Risks for Doosan’s SOFC, $974 M in Cancellations versus New 50 MW Capacity

Doosan Fuel Cell’s 2025 strategy represents a high-risk, high-reward pivot from its established Phosphoric Acid Fuel Cell (PAFC) technology to the more efficient Solid Oxide Fuel Cell (SOFC) market. This transition was not entirely voluntary; it was accelerated by the collapse of its legacy project pipeline, including nearly $1 billion in contract cancellations in early 2025. This turn of events placed immense pressure on the successful execution of its new SOFC manufacturing and commercialization plan, turning the year into a critical test of strategic resilience and operational capability.

• The year began with the cancellation of a $414 million, 100 MW hydrogen fuel cell project with KOMIPO in January, a major blow to its PAFC order book.
• By April, three additional PAFC-related contracts worth a combined $560 million were also terminated, bringing the total loss to over $974 million and underscoring the market’s shift away from the older technology.
• In response, Doosan aggressively executed its SOFC strategy by launching a new 50 MW annual capacity factory in South Korea, with mass production commencing in the second half of 2025.
• The company is now targeting high-growth sectors like AI data centers and hospitals, positioning its new SOFC products, which are based on licensed technology from Ceres Power, to compete directly with market leader Bloom Energy.

$974 M in PAFC Contract Losses, Doosan’s Pivot Catalyst

The termination of nearly $1 billion in legacy Phosphoric Acid Fuel Cell (PAFC) contracts in early 2025 acted as a powerful catalyst, forcing Doosan Fuel Cell to accelerate its pivot to the higher-efficiency SOFC market while simultaneously navigating severe financial headwinds. These cancellations highlighted the increasing market preference for newer, more efficient fuel cell technologies and exposed the vulnerability of Doosan’s previous project pipeline.

Doosan’s New Commercial Alliances, from Alleima to KEPCO (2025)

In response to its strategic pivot and the loss of its legacy contracts, Doosan moved decisively to establish a new commercial foundation for its SOFC business throughout 2025. The company forged critical new partnerships aimed at de-risking its supply chain, securing long-term revenue streams, and penetrating key growth markets for high-efficiency power generation, such as data centers and distributed power.

South Korea as Proving Ground for Doosan’s Global SOFC Ambitions

Doosan’s 2025 SOFC strategy is heavily concentrated in its home market of South Korea, which serves as a critical proving ground for its new manufacturing capabilities, commercial models, and technology integration before a broader global expansion. The company is leveraging domestic partnerships and government support for hydrogen to validate its products and build a track record for its new high-efficiency systems.

• The centerpiece of the strategy, the new 50 MW SOFC factory, is located in Saemangeum, South Korea, establishing a domestic manufacturing hub for the new technology.
• Initial commercial deployments are focused domestically, with the first sales of SOFC products targeted for local sites like data centers and hospitals before the end of 2025.
• Key commercial agreements secured in 2025, including the 20-year PPA with KEPCO and collaborations with SK Ecoplant and HD Hyundai, are with major South Korean entities, solidifying its local market position.
• Despite the domestic focus, Doosan initiated its first-ever export of core SOFC stacks to the European market in 2025, a clear signal of its long-term ambition to compete on a global scale.

SOFC Commercialization, Doosan’s Transition from PAFC

The year 2025 marks Doosan’s definitive technological transition from its mature Phosphoric Acid Fuel Cell (PAFC) products to the commercial-scale production of higher-efficiency Solid Oxide Fuel Cells (SOFC). This shift moves the licensed Ceres Power technology from a development-stage asset into a market-ready product line, targeting more demanding and profitable applications.

• Prior to 2025, Doosan’s primary focus was on large-scale PAFC projects, a business model that proved vulnerable as demonstrated by the massive contract cancellations early in the year.
• The launch of the 50 MW SOFC factory in the second half of 2025 represents a major milestone, making Doosan the first of Ceres Power’s strategic partners to achieve mass production scale.
• The new SOFC systems, boasting a high electrical efficiency of 54.3%, are now being deployed commercially, validated by the first domestic sales and a significant long-term power agreement with utility KEPCO.
• This technological upgrade allows Doosan to compete more effectively in power-intensive markets like AI data centers, where high efficiency, fuel flexibility, and continuous operation are critical requirements.

Doosan Shifts to SOFC for Mid-Term Growth
Doosan is strategically pivoting towards Solid Oxide Fuel Cell (SOFC) technology, projecting SOFC to drive mid-to-long-term growth from 2025, diversifying from its stable PAFC sales. Significant investments, including KRW 155.8 billion for a Gunsan SOFC factory, underscore this aggressive transition.

SOFC Targets Data Centers, Stack Foundries
This pivot signals Doosan’s intent to capture emerging high-growth markets like data centers and commercialize SOFC stack foundries from 2025, moving beyond traditional applications. The substantial facility investment (KRW 155.8B) positions Doosan for large-scale SOFC manufacturing, crucial for competitive advantage.

SWOT Analysis for Doosan’s High-Stakes SOFC Pivot

The strategic analysis reveals a company navigating a perilous but necessary transition. Its key strength lies in its new SOFC manufacturing capabilities and licensed technology, but this is counterbalanced by the significant weakness of recent financial losses and the external threat of dominant, well-capitalized competitors.

Doosan’s 2026 Trajectory, Converting 50 MW Capacity into Contracts

Doosan’s success in 2026 hinges entirely on its ability to convert its 50 MW of new SOFC manufacturing capacity into firm, large-scale commercial contracts, particularly in the hyper-competitive data center market. The initial agreements of 2025 are a start, but the coming year will determine if the high-stakes pivot can deliver sustainable growth.

• If Doosan announces a significant data center contract, particularly one exceeding 10 MW, with a major international or domestic client, watch for a sharp increase in market confidence and a validation of its competitive stance against Bloom Energy.
• If reports of a slow production ramp-up persist through mid-2026 and the 50 MW factory capacity remains visibly underutilized, watch for renewed investor skepticism and potential pressure to revise its growth forecasts downward.
• If the European export channel, initiated in 2025, expands with a named customer or a multi-unit framework agreement, this would signal successful geographic diversification beyond the Korean market and a crucial step toward becoming a global player.
