Top Solid Oxide Fuel Cell Companies

The global solid oxide fuel cell market is projected to reach USD 11.61 billion by 2030 from USD 2.98 billion in 2025, registering a CAGR of 31.2%. Market growth is driven by the increasing demand for clean and efficient power generation technologies, particularly due to decarbonization and net-zero commitments. Solid oxide fuel cells provide high levels of efficiency, fuel choice, and low emissions, enabling deployment in stationary power, combined heat and power systems (CHP), and industrial solutions. Improvements in materials, system integration, and digital control technologies are improving SOFC performance, reliability, and scalability. In addition, strict regulations associated with the environment and increased energy security concerns have prompted investment in resilient, low-carbon energy infrastructure. Key global and regional players continue to produce and solidify their market position through product portfolio additions, expanded R&D funding, and leveraging of extensive deployment experience in various applications.

Major players in the solid oxide fuel cell market include Bloom Energy (US), Mitsubishi Heavy Industries, Ltd. (Japan), AISIN Corporation (Japan), and Kyocera Corporation (Japan). These leading companies are adopting various growth strategies to strengthen their market presence, such as entering into long-term power purchase agreements (PPAs), forming strategic partnerships for system integration and deployment, and investing in R&D to enhance fuel cell efficiency, durability, and scalability. In addition, these players are expanding their manufacturing capabilities and leveraging collaborations with utilities and industrial partners to accelerate the commercialization of SOFC systems across residential, commercial, and industrial applications.  For example, in February 2025, Bloom Energy and Equinix partnered to add over 100 megawatts of fuel cell capacity across 19 Equinix data centers in six US states. Starting from a 1MW pilot in 2015, the partnership now includes 75MW operational and 30MW under construction, providing cleaner, on-site power to meet the growing energy demands of AI-driven computing. Bloom's fuel cells offer reliable electricity with minimal environmental impact, enhancing Equinix's sustainability efforts and reducing reliance on traditional grid power.
