Proven technology, U.S. partnership and AI-driven power demand create a new growth opportunity
Doosan Fuel Cell is gaining a foothold in the U.S. power market as demand for reliable electricity continues to surge alongside the rapid expansion of AI data centers.
The South Korean fuel cell maker recently signed a 501.4 billion won ($350 million) agreement with HyAxiom, the U.S. subsidiary of Doosan Corp., to supply phosphoric acid fuel cell (PAFC) systems for AI data centers in the United States.
The scale of the deal is significant, but its importance goes beyond the size of the contract. It marks Doosan Fuel Cell’s first entry into the U.S. power market and highlights the factors that have helped the company establish a competitive position in one of the world’s fastest-growing energy markets.
A major advantage is Doosan Fuel Cell’s extensive experience in fuel cell deployment. The company has accumulated more than 800 MW of installed capacity and operates a major manufacturing facility in Iksan, South Korea. Its PAFC systems are designed for stable, continuous power generation, making them well suited to the requirements of AI data centers.
AI data centers require highly reliable electricity to operate computing infrastructure around the clock. At the same time, power shortages and grid congestion are emerging as major obstacles to data center expansion in the United States.
The rapid growth of AI has widened the gap between the speed of data center construction and the development of power infrastructure. New power plants and transmission networks can take years to build, while data center projects often need electricity on much shorter timelines.
This mismatch is driving interest in behind-the-meter power generation, where electricity is produced directly at or near the facility where it is consumed. Fuel cells are emerging as a potential solution because they can provide continuous power without depending entirely on expanded transmission infrastructure.
This shift in the U.S. power market gives Doosan Fuel Cell an opportunity to apply its existing technology to a rapidly expanding customer base.
Another important factor is the role of HyAxiom. Based in the United States, the company provides sales, engineering, project execution, commissioning and long-term service capabilities across North America and Europe.
The partnership allows Doosan Fuel Cell to combine its manufacturing and fuel cell technology with HyAxiom’s local market expertise. This is particularly important for large data center projects, where customers require more than equipment. Engineering, installation, commissioning and long-term maintenance are all critical components of the project.
Deployment speed could also give Doosan Fuel Cell an advantage. The two companies aim to complete installation at U.S. customer sites within roughly one year of signing a contract, potentially allowing data center operators to secure additional power without waiting for lengthy grid expansion projects.
The modular structure of the fuel cell systems provides another benefit. Capacity can be added in stages as electricity demand increases, giving data center operators greater flexibility as AI computing requirements continue to grow.
Doosan Fuel Cell also has the potential to provide more than electricity. Heat generated during fuel cell operation can be integrated with absorption chillers or heat pumps for data center cooling.
Cooling represents a significant energy requirement for large-scale data centers. Integrating power generation and cooling could therefore improve overall energy efficiency while creating an additional value proposition for customers.
The technology also offers a potential pathway toward hydrogen-based power generation. As hydrogen infrastructure expands, existing systems could potentially be adapted to use hydrogen fuel, supporting customers seeking to reduce carbon emissions over the longer term.
Doosan Fuel Cell’s expansion into the U.S. is also backed by capabilities developed through Korea’s growing hydrogen economy. Government policies and the development of the domestic hydrogen power generation market have helped strengthen demand, technology and supply chains for fuel cell systems.
The company has worked with Korean partners to improve its technology and supply network and currently has annual production capacity of approximately 275 MW. It is also considering additional capacity expansion in response to expected growth in global demand.
The latest agreement with HyAxiom could therefore represent more than a single project. It provides Doosan Fuel Cell with an entry point into a U.S. market where AI-driven electricity demand is expected to remain strong.
The company is also looking beyond data centers. Semiconductor plants, battery factories and other large industrial facilities face similar challenges in securing stable and timely power supplies, creating additional opportunities for distributed fuel cell generation.
Competition in the U.S. power market is expected to intensify as companies seek solutions to the growing electricity requirements of AI infrastructure. Doosan Fuel Cell, however, enters the market with an established technology platform, significant deployment experience, manufacturing capabilities and a U.S.-based partner with project execution expertise.
The key challenge will now be converting its first major U.S. contract into a broader pipeline of projects.
If it succeeds, the agreement could become an important starting point for Doosan Fuel Cell’s expansion in the U.S. distributed power market and strengthen its position as AI data centers continue to reshape the country's energy landscape.
