Ceres launches Ceres® Endura - A game-changing solid oxide platform

• Designed for scale reduces risk and accelerates deployment
• Built to last works in the real world, with a five-year stack life
• Low cost up to onethird lower fuel cell system cost at scale
  

HORSHAM, United Kingdom, April 15, 2026 (GLOBE NEWSWIRE) -- Ceres Power Holdings plc (Ceres) today launched Ceres^® Endura, its flagship solid oxide stack platform designed to meet the surging demand for resilient, efficient, onsite power for data centres and other energyintensive applications.

From a single production facility, Ceres partners can unlock access to both the power and hydrogen markets from a shared platform. Fuel flexibility allows for operation on natural gas today, while supporting hydrogen and other low carbon fuels tomorrow.

Systems can be installed and commissioned in months rather than years, avoiding the long lead times associated with grid upgrades and conventional infrastructure. The platform supports high voltage DC architectures up to 800V & beyond, aligned with modern data centre standards and enabling fast load response from a compact footprint.

Designed for scale

Every element of Ceres Endura has been engineered for reliable power to reduce risk, enable scale and accelerate deployment. Using steel-supported cells, Ceres Endura operates at the lower temperature of 450630°C, compared to high temperature solid oxide. This allows the use of widely available, cost-effective and recyclable materials. This proprietary design from Ceres lowers overall fuel cell system costs by around a third, whilst also reducing supplychain risk, therefore supporting gigawattscale manufacturing across power and hydrogen.

Designed to perform in realworld power environments

For power generation, Ceres Endura delivers over 65% electrical efficiency on natural gas and over 90% total efficiency in combined heat and power applications. The performance holds through the products life, making it more efficient than the competition. Furthermore, it is developed to withstand all forms of real-world use to enable rapid load following with robustness for emergency stops and rapid power and thermal cycles.

Engineered for lowcost hydrogen

When integrated with heat from industrial applications, Ceres Endura achieves around 30% higher efficiency than conventional low-temperature electrolysis, significantly lowering operating costs and supporting industrial scale hydrogen economics.

Ceres Endura, combined with Ceres partnership model, provides a direct route to market for companies looking to scale quickly and competitively. Ceres supports partners through a proven business model and factory blueprint, enabling local manufacturing, access to national incentives, and export into global markets.

Ceres Endura turns decades of solid oxide development into a mature platform thats ready for scale and built to last
