In a world powered by intermittent renewable energy, electrolyzers will play a central role in converting electrical energy into chemical energy, thereby decoupling the production of transport fuels and chemicals from today's fossil resources and decreasing the reliance on bioenergy. Solid oxide electrolysis cells (SOECs) offer two major advantages over alternative electrolysis technologies. First, their high operating temperatures result in favorable thermodynamics and reaction kinetics, enabling unrivaled conversion efficiencies. Second, SOECs can be thermally integrated with downstream chemical syntheses, such as the production of methanol, dimethyl ether, synthetic fuels, or ammonia. SOEC technology has witnessed tremendous improvements during the past 10 to 15 years and is approaching maturity, driven by advances at the cell, stack, and system levels.
在一个由间歇性可再生能源驱动的世界里，电解槽将在将电能转化为化学能方面发挥核心作用，从而使运输燃料和化学品的生产与今天的化石资源脱钩，并减少对生物能源的依赖。固体氧化物电解槽 (SOEC) 相对于其他电解技术具有两大优势。首先，其工作温度高，导致热力学和反应动力学有利，实现了无与伦比的转换效率。其次，SOEC 可以与下游的化学合成进行热集成，例如甲醇、二甲醚、合成燃料或氨的生产。SOEC 技术在过去 10 到 15 年中取得了巨大的进步，并在电池、堆栈和系统层面的进步的推动下，逐渐走向成熟。
