Demand response is a viable concept to deal with and benefit from fluctuating electricity prices and is of growing interest to the electrochemical industry. To assess the flexibility potential of such processes, a generic, interdisciplinary methodology is required. We propose such a methodology, in which the electrochemical fundamentals and the theoretical potential are determined first by analyzing strengths, weaknesses, opportunities, and threats. Afterward, experiments are conducted to determine selectivity and yield under varying loads and to assess the additional long-term costs associated with flexible operation. An industrial-scale electrochemical process is assessed regarding its technical, economic, and practical potential. The required steps include a flow sheet analysis, the formulation and solution of a simplified model for operation scheduling under various business options, and a dynamic optimization based on rigorous, dynamic process models. We apply the methodology to three electrochemical processes of different technology readiness levels—the syntheses of hydrogen peroxide, adiponitrile, and 1,2-dichloroethane via chloralkali electrolysis—to illustrate the individual steps of the proposed methodology.

评估电化学过程的可实现灵活性潜力
需求响应是一个可行的概念，可以处理波动的电价并从中受益，电化学行业越来越感兴趣。为了评估此类流程的灵活性潜力，需要通用的跨学科方法。我们提出了这样一种方法，首先通过分析优势、劣势、机会和威胁来确定电化学基础和理论潜力。然后，进行实验以确定不同负载下的选择性和产量，并评估与灵活操作相关的额外长期成本。评估工业规模的电化学过程的技术、经济和实际潜力。所需的步骤包括流程图分析、各种业务选项下操作调度的简化模型的制定和解决，以及基于严格的动态流程模型的动态优化。我们将该方法应用于不同技术准备水平的三个电化学过程——通过氯碱电解合成过氧化氢、己二腈和 1,2-二氯乙烷——以说明所提议方法的各个步骤。
