Summary
Solar thermal technology is a cornerstone of sustainable development, providing a clean, renewable energy source with enormous global potential. Harnessing solar energy represents a practical solution to meet the growing demand for thermal energy while maintaining environmental sustainability. The solar thermal sector has seen increasing adoption in numerous applications, including process heating, cooling, drying, distillation, and power generation. To fully harness solar thermal energy, optimizing collection and storage systems, along with intelligent demand-side management, is essential to address the intermittent nature of solar energy. This Special Collection provides a forum for the publication of the latest thought-provoking research in the field of solar thermal energy collection and storage technologies. This issue will primarily focus on presenting the latest developments, advanced analyses, and performance improvements for various solar thermal collectors and their applications, including water, air, and concentrator types. It also focuses on solar distillation systems, which are currently receiving significant attention due to the high energy consumption of conventional desalination systems and environmental concerns. We invite submissions of research papers that include the latest technical developments, comprehensive reviews, in-depth case studies, analytical papers, and multidisciplinary evaluations related to " Thermal Solar Energy System Technology and Future Development".
Potential topics may include, but are not limited to the following:
