Energy efficiency improvements can enhance industry’s decarbonization. A major challenge however is that the energy efficiency potential often remains untapped, due, among other things, to the lack of information on energy end-use and available energy efficiency measures. Further, this lack of information also makes the deployment of energy efficiency difficult to monitor and evaluate. The creation of a standard or taxonomy on how to categorize energy end-use for major industries would help to close this knowledge gap. This paper presents a novel taxonomy for energy end-use in the food industry, with four hierarchical levels. Further, results show that the production process utilizes two-thirds of the total energy used in the food industry and only one-third is used for support processes. Another result is that heat processing and space heating are the most intensive unit processes in terms of energy and carbon dioxide emissions for production and support processes, respectively. The paper also presents an array of energy performance indicators for the identified energy-intensive processes. The case study was carried out in the Swedish food industry. However, taxonomy and energy performance indicators can be generalized internationally. In addition to the above results, this research presents a novel concept of the energy planning framework, which helps with simple and effective planning of energy improvement activities in an industrial context. The energy planning framework can help in benchmarking, setting targets, and monitoring energy performance in the industry.

能源效率的提高可以促进工业的脱碳。然而，一个主要的挑战是，由于缺乏关于能源最终使用和可用能源效率措施的信息，能源效率潜力往往仍未开发。此外，信息的缺乏也使得能源效率的部署难以监测和评估。创建关于如何对主要行业的能源最终用途进行分类的标准或分类法将有助于缩小这一知识差距。本文介绍了食品行业能源终端使用的新分类法，分为四个层次。此外，结果表明，生产过程使用了食品工业总能源的三分之二，只有三分之一用于支持过程。另一个结果是，就生产和支持过程的能源和二氧化碳排放而言，热处理和空间加热分别是最密集的单元过程。该文件还针对已确定的能源密集型过程提出了一系列能源绩效指标。案例研究是在瑞典食品工业中进行的。然而，分类学和能源绩效指标可以在国际上推广。除了上述结果，本研究还提出了能源规划框架的新概念，有助于在工业环境中简单有效地规划能源改进活动。能源规划框架有助于对标、设定目标和监测行业能源绩效。
