Abstract

With increasing energy demands, technologies evolved utilizing both renewable and non- renewable resources. With goal of achieving sustainability, solar energy has emerged as one of the potential renewable energy sources globally. The aim of this study is to present a thorough analysis of heat pipe technologies integrated with solar parabolic trough collectors (PTCs). This study focusses on performance improvement of PTC and heat pipe design. In solar energy systems, parabolic collectors are primarily employed for the generation of concentrated solar power (CSP). Heat pipes can be integrated into the system to increase output. With integration of heat pipes, the system is capable producing improved output. Moreover, the economic and environmental advantages of the system is also covered. The paper also identifies future research, including development of nanofluids and optimization of heat pipe designs for improving the performance under varying solar radiation scenarios. PTCs and heat pipes integration have potential to transform solar thermal energy technology and support achieving Sustainable development goals of clean energy and climate action by overcoming these challenges.
