Abstract

Insulating materials are key components of power systems for the generation, transmission, storage, conversion and utilization of electrical energy. However, most insulating materials remain unsustainable and pose increasing environmental concerns. Developing sustainable insulating materials is therefore essential for achieving long-term sustainability in power systems. This Review summarizes the gas, liquid and solid insulating materials widely used in power systems and outlines strategies for improving their sustainability, including substitution, benign degradation, recycling, reuse and resource conversion. The Review also highlights the scientific and technological challenges in materials design, waste conversion and engineering applications, together with pathways involving policy frameworks, technology maturity and industry standards towards global net zero goals. This Review provides a holistic view of sustainable gas, liquid and solid insulating materials, focusing on substitution, benign degradation, recycling, reuse and resource conversion to support net zero power systems.

电力系统用可持续绝缘材料

绝缘材料是电力系统中电能的产生、传输、存储、转换和利用的关键部件。然而，大多数绝缘材料仍然是不可持续的，并造成越来越多的环境问题。因此，开发可持续绝缘材料对于实现电力系统的长期可持续性至关重要。综述了电力系统中广泛使用的气体、液体和固体绝缘材料，并概述了提高其可持续性的策略，包括替代、良性降解、回收、再利用和资源转化。该报告还强调了材料设计、废物转化和工程应用方面的科技挑战，以及涉及政策框架、技术成熟度和行业标准的实现全球净零目标的途径。本综述提供了可持续气体、液体和固体绝缘材料的整体观点，重点是替代、良性降解、回收、再利用和资源转换，以支持净零电力系统。
