Decarbonization of the power sector offers ammonia industry an opportunity to reduce its CO₂ emissions through sector coupling. Extending from our previous work, we propose a power‐based process for ammonia and nitric acid production. The coupling of nitric acid production facilitates highly efficient heat integration between steam electrolysis and the rest of the process. We investigate the economic performance of the production complex through a model‐based dynamic optimization approach, considering scenarios with or without incorporation of intermittent wind power as well as deployment of battery storage. In all cases, the wind power integration proves to be economic with a peak‐to‐base load ratio of up to 2.3. The new process reduces primary energy consumption by more than 13% compared to conventional technologies. However, it is only economically competitive with help of either a low‐cost battery storage or a higher carbon price on fossil fuels. The results also confirm the importance of considering process dynamics during process design.

可再生生产氨和硝酸

电力行业的脱碳为氨行业提供了减少其CO ₂的机会通过部门耦合产生的排放。在先前工作的基础上，我们提出了一种基于动力的氨和硝酸生产工艺。硝酸生产的耦合促进了蒸汽电解与其余工艺之间的高效热整合。我们通过基于模型的动态优化方法研究生产综合设施的经济绩效，考虑了是否包含间歇性风能以及部署电池存储的情况。在所有情况下，风电集成都被证明是经济的，峰值/基本负载比高达2.3。与传统技术相比，新工艺将一次能源消耗降低了13％以上。然而，只有通过低成本的电池存储或更高的化石燃料碳价，它在经济上才具有竞争力。结果还证实了在过程设计中考虑过程动力学的重要性。
