Abstract

The global freshwater crisis poses an existential threat to sustainable development worldwide. Desalination has emerged as a critical solution, but conventional fossil-fuel plants are energy-intensive and emit substantial greenhouse gases. Concentrating solar power (CSP) offers a promising renewable pathway to drive thermal desalination processes. However, CSP-desalination integration requires thoughtful system configuration design to maximize efficiency. This review consolidates insights from diverse case studies worldwide, highlighting the merits of CSP-desalination integration, such as significantly improved energy efficiency and sustainability through the utilization of renewable solar energy and enabling multi-generation systems for combined electricity, water, and heating services. The review's novelty lies in its systematic assessment of modeling simulations, pilot facilities, and commercial plants to elucidate key learnings on technical configurations and optimizations. It also proposes innovative configurations to enhance system efficiency and performance. The review identifies and analyzes optimization strategies employed in the reviewed case studies, including the role of thermal storage for 24-h operation, cogeneration for enhanced energy utilization, and multi-generation systems for combined electricity, water, and heating services. Recognizing the growing interest in hybrid systems, this review specifically examines the integration of thermal and membrane desalination processes driven by CSP, highlighting potential synergies and performance enhancements. The review provides a critical assessment of the diverse case demonstrations proving the technical viability of concentrated solar desalination under proper design conditions. It offers valuable insights on configurations that maximize renewable energy utilization and minimize water costs tailored to local ambient and operational parameters. Furthermore, it provides a forward-looking perspective by exploring the application of supercritical CO2 cycles in CSP-desalination systems, examining their potential for high-temperature heat supply without compromising power generation efficiency.

实现聚光太阳能热海水淡化的前景：技术配置和优化回顾

全球淡水危机对全世界的可持续发展构成了生存威胁。海水淡化已成为一个重要的解决方案，但传统的化石燃料发电厂能源密集，并排放大量温室气体。聚光太阳能（CSP）为推动热海水淡化过程提供了一条前景广阔的可再生途径。然而，聚光太阳能发电与海水淡化的整合需要深思熟虑的系统配置设计，以最大限度地提高效率。本综述综合了世界各地不同案例研究的见解，强调了 CSP-海水淡化一体化的优点，例如通过利用可再生太阳能显著提高能源效率和可持续性，并实现多发电系统的电力、水和供热服务。该综述的新颖之处在于它对模型模拟、试验设施和商业工厂进行了系统评估，以阐明技术配置和优化方面的关键经验。它还提出了提高系统效率和性能的创新配置。综述确定并分析了所审查的案例研究中采用的优化策略，包括热存储在 24 小时运行中的作用、热电联产在提高能源利用率中的作用，以及多发电系统在电力、水和供热综合服务中的作用。考虑到人们对混合系统的兴趣与日俱增，本综述特别研究了由 CSP 驱动的热能和膜法海水淡化过程的整合，强调了潜在的协同作用和性能提升。综述对各种案例演示进行了批判性评估，证明了聚光太阳能海水淡化在适当设计条件下的技术可行性。它为根据当地环境和运行参数最大限度地利用可再生能源和最小化水成本的配置提供了宝贵的见解。此外，它还提供了一个前瞻性视角，探讨了超临界二氧化碳循环在聚光太阳能海水淡化系统中的应用，研究了其在不影响发电效率的情况下提供高温热能的潜力。

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.
