Abstract

Latent heat thermal energy storage, by using phase change materials (PCMs), is considered as a promising technology that can be integrated into concentrated solar power (CSP) applications to mitigate the load and electricity supply. Multiple PCMs connected in series has attracted considerable research attention as this configuration has the potential to improve the thermal performance compared to single PCM storage. However, this technology has not yet been deployed in commercial CSP plants. One of the major restrictions is the lack of reliable thermophysical property data for high temperature PCMs. This study gives a broad review of the experimentally verified PCMs with melting temperatures from approximately 500 °C–700 °C, applicable to CSP systems. A further twelve PCM candidates, containing low-cost sodium and/or potassium salts, were identified in this study and their thermophysical properties were experimentally evaluated. It was found that nine of the new candidates can be used as PCMs.

500 - 700℃高温相变材料候选材料的回顾和表征

利用相变材料(PCMs)的潜热储能技术被认为是一种很有前途的技术，可以集成到聚光太阳能(CSP)应用中，以减轻负荷和电力供应。多个PCM串联已经引起了相当多的研究关注，因为与单个PCM存储相比，这种配置有可能改善热性能。然而，这项技术尚未在商业CSP工厂中部署。其中一个主要的限制是缺乏可靠的高温PCMs热物性数据。本研究对实验验证的pcm进行了广泛的回顾，其熔化温度约为500°C - 700°C，适用于CSP系统。本研究还确定了另外12种含低成本钠盐和/或钾盐的PCM候选材料，并对其热物理性质进行了实验评估。结果发现，新候选人中有9人可以作为PCMs使用。

期刊介绍： The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change. Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
