Special Issue Information
Dear Colleagues,
The global transition toward sustainable and low-carbon energy systems requires efficient technologies for energy conversion, storage, and sector integration. In this context, solid oxide cells (SOCs) have attracted significant attention due to their high efficiency, fuel flexibility, and potential to support the emerging hydrogen economy. SOC technologies include solid oxide fuel cells (SOFCs) for electricity generation and solid oxide electrolysis cells (SOECs) for hydrogen production and energy storage. In addition, reversible solid oxide cells (rSOCs) offer the possibility of operating in both fuel cell and electrolysis modes, enabling the development of integrated solutions for energy conversion and storage in renewable energy systems.
SOCs play an important role in hydrogen and Power-to-X (P2X) technologies, where renewable electricity can be converted into hydrogen or other energy carriers. Through efficient electrochemical energy conversion, SOC systems can contribute to sustainable hydrogen production, energy storage, and the integration of intermittent renewable energy sources. Their high operating temperatures allow the use of a wide range of fuels and enable efficient catalytic and electrochemical reactions, making them promising technologies for future energy systems.
Recent years have witnessed significant progress in advanced ceramic materials, particularly in the development of mixed ionic–electronic conductors, improved electrode and electrolyte materials, and innovative cell architectures and designs. Advances in interfaces and surface engineering have also contributed to improved electrochemical performance and stability. Furthermore, emerging fabrication methods, including additive manufacturing and advanced processing techniques, are opening new opportunities for the scalable and cost-effective production of high-performance SOC components.
Despite these advances, several challenges remain before SOC technologies can achieve widespread commercial deployment. Long-term durability, performance degradation, and material stability under realistic operating conditions continue to be important research topics. Efforts to understand degradation mechanisms, improve device lifetime, and optimize materials and microstructures are essential for reliable and economically viable SOC systems.
In addition, the modelling and simulation of SOC systems are increasingly important tools for understanding electrochemical processes, transport phenomena, and system-level performance. These approaches support the design and optimization of materials, cell architectures, and operating strategies.
This Special Issue aims to provide a platform for researchers and engineers to present recent advances in energy conversion and storage using advanced solid oxide cells and electrolysers. We welcome contributions addressing materials development, cell design, fabrication and processing technologies, advanced characterization, modelling and simulation, and system integration. We are particularly eager to publish studies related to hydrogen production and storage, renewable energy integration, and P2X technologies.
By bringing together contributions from academia, research institutes, and industry, this Special Issue seeks to highlight emerging developments and promote further innovation in SOC technologies for sustainable energy systems.
