HyAxiom's David Alonso on fuel cells and time to power for AI data centers

HyAxiom, a Connecticut-based fuel cell manufacturer and part of the Doosan group, is addressing the growing power challenges faced by rapidly scaling AI data centers. As AI facilities expand from tens of megawatts to potentially gigawatt-scale operations, traditional electric grids and local utilities struggle to deliver sufficient capacity quickly. HyAxiom’s stationary fuel cells offer a solution by enabling on-site power generation that can be deployed rapidly—within about 12 months—bypassing grid delays. Their fuel cells also produce significantly lower emissions compared to conventional combustion-based power sources, addressing environmental concerns as data centers grow more power-dense. A key product in HyAxiom’s portfolio is the PureCell® Model 400, a modular, containerized fuel cell system that integrates fuel handling, electricity generation, and power conversion. Each unit delivers 460 kilowatts and can be scaled incrementally to meet specific data center demands, from small to very large capacities. This modularity and rapid deployment capability make fuel
