Ceres Power Holdings plc specializes in the development of solid oxide fuel cell (SOFC) and solid oxide electrolyzer cell (SOEC) technologies, primarily through its proprietary SteelCell platform. The company's technology enables the highly efficient conversion of fuels such as natural gas, biogas, and hydrogen into electricity, and can also be run in reverse as an electrolyzer to produce green hydrogen. Rather than manufacturing systems at scale, Ceres employs an asset-light licensing model, partnering with major global engineering and manufacturing firms like Doosan, Delta Electronics, and Denso. The company generates revenue through upfront license fees, engineering services, and royalties on partner sales. Headquartered in Horsham, UK, Ceres aims to decarbonize energy-intensive industries, commercial applications, and data centers globally.
