Solid oxide technology: Powering the net-zero future
Combatting climate change and achieving net-zero emissions is one of the greatest challenges—and opportunities—of our time. It demands efficient, scalable and sustainable solutions that reduce reliance on fossil fuels while meeting the global needs for energy affordability and security. Solid oxide technology offers a promising solution with high efficiency, low emissions, and the ability to support both power generation and energy storage, making it key to a more sustainable and resilient energy future.
Solid oxide technology gets its name from the ceramic metal oxide materials it uses, which enable the most efficient conversion of molecules into electricity. Operating at temperatures between 450–1000°C, they excel in both fuel-flexible power generation and green hydrogen production, both of which are essential to delivering a net zero future. Unlike some other clean energy technologies, solid oxide cells do not need to rely on expensive catalysts like platinum, making them cost-effective and resource-efficient. Solid oxide technology includes two primary applications:
- Solid Oxide Fuel Cells (SOFCs): SOFCs generate electricity by converting chemical energy in fuels like hydrogen, natural gas, or biogas. They are highly efficient, with minimal emissions, and are suitable for stationary power generation in industrial facilities and data centres, as well as auxiliary power in marine applications. Robust SOFCs can also be used in mobile applications to power ships. SOFCs provide a cleaner, more reliable energy source for applications requiring high performance and resilience.
- Solid Oxide Electrolysis Cells (SOECs): SOECs work in reverse, using electricity—ideally from renewable sources—to split water into hydrogen and oxygen. This process produces green hydrogen, which is essential for decarbonising industries that cannot be electrified directly like ammonia, steel, sustainable aviation fuels and chemicals.
Why does this matter?
Solid oxide technology addresses the need for a balanced energy future by providing clean, reliable energy, reducing operational costs, and ensuring resilience in the face of rising energy demands. As the world seeks innovative pathways to decarbonisation, solid oxide technology represents critical opportunities to drive both environmental and economic progress. The next blogs will further demonstrate how Ceres’ solid oxide technology stands above the competition. These technologies are not just the future—they are today’s solution for a cleaner tomorrow.
