Doosan Fuel Cell Lands Record SOFC Export Deal with Reverion for Europe

Doosan Fuel Cell just scored a big win by landing a supply contract with Germany’s climate-tech firm, Reverion GmbH. This deal, worth around 108.7 billion won, is Doosan's largest overseas order to date. They're set to make staged deliveries of mid-to-low-temperature solid oxide fuel cell stacks all the way through the second half of 2027. It's pretty exciting, as it shows Doosan is stepping up its game from just focusing on the domestic market to making waves globally.

Reverion plans to use these fuel cell stacks in their reversible SOFC/SOEC platforms, which will be utilized for generating power from biogas and producing hydrogen and methane across Germany and beyond. This not only highlights the advancement of fuel cell technology but also aligns with Europe’s strong push towards renewable energy solutions and distributed generation.

Some Background

Solid oxide fuel cells have come a long way thanks to years of research into high-temperature electrochemical conversion. These systems, which now run around 600°C, have transitioned from mere prototypes to commercially viable designs. Doosan began mass production under a licensing agreement with the UK’s Ceres Power Holdings plc and is utilizing the SteelCell architecture to ramp up stack manufacturing at its facility in Korea's Saemangeum region. According to their materials, Doosan's modular 5 kW core stacks and larger modules are well-suited for various stationary applications—think data centers and marine vessels.

At their manufacturing plant in Gunsan, South Korea, Doosan boasts an impressive annual capacity of 50 MW dedicated to SOFC systems. This level of production, along with their rigorous quality control, has earned them the reputation of a trusted supplier for European clients. Their mid-scale modules are engineered for data centers and microgrids, where keeping systems running smoothly and having flexible fuel options are crucial.

On the flip side, Reverion GmbH originated from a spin-off at the Technical University of Munich and has developed a reversible SOFC/SOEC platform that switches between electricity generation from biogas and high-temperature electrolysis for green hydrogen or methane. They've even verified the performance of Doosan's stacks before finalizing the deal, which gives them an extra layer of confidence moving forward.

The Market Impact

This contract is a game-changer for Doosan Fuel Cell, positioning them as a core supplier for European integrators rather than just a vendor of complete systems. This significant financial agreement will help maintain factory utilization at their Korean stack production site, diversify their revenue streams, and bolster their standing in future licensing talks. By exporting key modules instead of entire systems, Doosan can cater to various integrators and ramp up economies of scale in a highly competitive market, where manufacturing costs and reliable performance matter.

For Reverion, having a solid stack supply from a reliable mass-production partner helps mitigate project risks and supply chain issues. The phased delivery plan extending through 2027 allows for step-by-step integration testing and gradual rollouts at biogas sites and green energy plants across Germany. This approach fits neatly into Europe’s broader drive for distributed generation, biogas enhancement, and renewable hydrogen infrastructure. As projects move forward, investor interest in low-emission distributed assets could pick up steam.

Additionally, this deal aligns seamlessly with Europe’s goals for industrial decarbonization, where cutting-edge fuel cell technology contributes to grid stability and promotes carbon-negative strategies and flexible energy markets. As the demand for solid oxide technology remains strong—especially in backup systems, data centers, and microgrids—stakeholders are eager to balance the intermittent nature of renewable energy sources and bio-derived feedstocks.

Quick Technical Snapshot

Mid-to-Low Temperature SOFC: The stacks produced by Doosan operate around 600°C, which helps decrease thermal stress and broadens their material choices compared to older models running at 800°C. Each module connects several 5 kW cells in series to boost output, and balance-of-plant components manage power, regulate heat, and handle fuel reforming or direct hydrogen feeds.

Reversible Operation: The platform created by Reverion can toggle between fuel cell and electrolysis modes. In fuel cell mode, it will generate electricity from biogas or hydrogen-rich gas, while in electrolysis mode, it can split water or CO₂ into hydrogen or methane. This high-temperature reversibility takes advantage of process heat to enhance overall efficiency, although it does require robust sealing and effective thermal management.

Key Takeaways

What’s Happening in the Market

Other players in hydrogen fuel cell news are making strides in securing European contracts for low-temperature SOFC stacks, but few can match Doosan’s scale of operations or breadth of offerings. While several membrane-electrode assembly providers are looking into PEM electrolyzers, traditional turbine manufacturers are shifting gears toward hydrogen combustion. In the niche of reversible solid oxide platforms, interest is rising, particularly in projects that connect biogas valorization with hydrogen storage solutions. As the market continues to evolve, a multi-technology portfolio could soon become the standard.

The Road Ahead

With deliveries set to begin and roll out through late 2027, this partnership has the potential to inspire follow-up orders and reinforce the modular stack-supply model within Europe. All eyes will be on execution risks, stack longevity, and integration effectiveness as key indicators for widespread adoption. Ultimately, solid on-field performance might just position Doosan Fuel Cell and Reverion as frontrunners in a market that's gearing up for significant growth as Europe transitions to cleaner energy sources.
