中德能效基准专家研讨会——聚焦水泥与玻璃行业

2023-10-13 18:09:15

此次会议重点关注水泥和玻璃行业工艺生产的能效基准。

9月20日,中德专家就两国工业能效基准开展了研讨和交流,重点关注水泥和玻璃行业工艺生产的能效基准。此次研讨会由德国国际合作机构(GIZ)和中国标准化研究院(CNIS)在中德能源与能效合作伙伴框架下举办。两国专家介绍了水泥和玻璃行业的现有能效基准。随后,来自政府、学术界和工业界的与会者围绕中德能效测评方法的异同,如何更好地收集数据、保证数据质量以及应对行业内部的复杂性展开讨论。

工业能效基准——评估节能潜力的重要工具

中国和德国都致力于提高工业领域整体能效,促进工业节能减排,助力实现碳中和目标。德国承诺2045 年实现碳中和,并制定了一个具有约束力的目标,即到2030年终端能源消耗较2008年减少26.5%。中国承诺到2060年前实现碳中和,《“十四五”节能减排综合工作方案》提出到2025年,全国单位国内生产总值能源消耗比2020年下降13.5% 。提高能源效率,减少能源消费是以相对较低的成本减少碳排放的核心手段,其中高耗能行业的能效提高发挥着尤为重要的作用。因此,工业能效基准是本次研讨会的重点。  

工业能效基准被视为未来评估节能潜力的重要工具。通过能效基准,可以对能效或碳排放水平进行企业内部或行业内部对标,从而促进和支持企业的能源管理,并帮助分析和制定相关政策,提高行业能源效率。在过去十年中,德国一直在讨论如何建立行业内部能效基准,但到目前为止,实施工作仍处于起步阶段。

会议讨论环节展示中德两国在制定行业能效基准方面都面临挑战,如高质量行业能效数据的收集。在德国,企业数据普遍是公开的,而在中国,数据获取的途径有限。双方都强调,收集数据需要训练有素的专业人员,以避免误差。在为特定行业制定能效基准时,工艺流程或产品甚至企业所处海拔差异带来的复杂性问题仍然普遍存在。为了进一步应对这些挑战,双方强调希望继续就能效和碳排放基准进行交流。

The title is "Statistics of National Key Aggregate Mine Transactions in April". The table counts the transactions of some key aggregate mines in China with a transaction price of more than 50 million yuan, including provinces, cities, names of mining rights, bidders and other information. Because there is no year-on-year and ring-to-ring data, it is impossible to know exactly the change value, but from the transaction price point of view, there are higher and relatively lower values. One of the transaction prices is relatively high and the other is relatively low, but the specific value can not be clearly stated because it is not shown.
