UK technology licensor Ceres has launched a new 10.8kW solid oxide stack, which it believes could meet growing demand for on-site data centre power and cut green hydrogen production costs.
The Endura stack is based on Ceres’ steel substrate-based solid oxide cells, which operate at 450–630ºC. It can be used for both power generation in fuel cell configurations and hydrogen production in electrolysis setups.
“Ceres Endura turns decades of solid oxide development into a mature platform that’s ready for scale and built to last,” said Nick Lawrence, Chief Product Officer.
In power generation, Ceres claims the stack offers 69% electrical efficiency on natural gas, and over 90% total efficiency for combined heat and power applications.
For electrolysis, the company said the stack can produce 20.88kg per day of hydrogen at 34.5kWh per kg. It says that when using waste industrial heat, the stack is around 30% more efficient when using industrial waste heat than “conventional low-temperature electrolysis.”
The stack configuration has been launched with a five-year lifetime – a sign of the degradation rates experienced in higher-temperature platforms.
It follows Ceres’ 2025 launch of its new strategy to prioritise opportunities for its solid oxide technology in fuel cell applications.
While solid oxide fuel cells (SOFC) are capable of running on hydrogen, Ceres argues natural gas offers a faster route to meet increasing demand for behind-the-meter power solutions, with the option to switch to hydrogen in the future.
Doosan Fuel Cell – Ceres’ first fuel cell licensee – opened a in South Korea to manufacture fuel cell systems in 2025 for stationary natural gas-fuelled power generation.
Last month, energy major a partnership agreement with the company to explore natural gas-fuelled fuel cells to help meet onsite power generation for European data centres and industrial sites.
While natural gas fuel cells do produce some carbon dioxide emissions, they are lower than the comparable combustion-based systems, which also generate nitrogen oxides and particulate emissions.
Ceres has increasingly been positioning its solid oxide tech as a long-term play in green hydrogen production, with demand for the gas forming far slower than original industry estimates.
Solid oxide electrolysers remain nascent, with no large-scale plants operating globally.
