Reversible solid oxide cells (rSOCs) are emerging as a promising technology for flexible energy conversion, long-duration energy storage, and renewable energy integration. By enabling bidirectional conversion between electricity and hydrogen within a single system, rSOCs address key challenges associated with renewable intermittency, grid flexibility, and seasonal energy storage. Recent advancements in cell materials, stack architectures, thermal management, and system integration have improved efficiency, durability, and operational flexibility while expanding opportunities for hydrogen production, power generation, and Power-to-X applications. Growing investments in hydrogen infrastructure, industrial decarbonization, and integrated energy systems are accelerating commercialization and positioning rSOCs as a critical enabler of resilient, low-carbon, and interconnected energy networks.
