Interconnected with solar collectors such as parabolic throughs and flat plate collectors, solar-generated thermal energy storage devices are essential components of sustainable energy solutions. This study examines the application of hybrid nanofluids as a viable working fluid in thermal energy storage units, specifically emphasizing their capacity to enhance system efficiency. The study emphasizes the efficacy of hybrid nanofluids, which consist of oil and nanoparticles, as efficient heat transfer fluids in thermal energy storage and heat transmission systems based on solar energy. The key results emphasize the exceptional heat transmission properties of multi-walled carbon nanotubes and alumina NPs when distributed in different base fluids. In addition, phase change materials such as erythritol and nitrate salt are identified as well-suited options for effectively storing thermal energy. During periods of low sunshine, the stored energy becomes extremely important, providing a consistent and dependable energy source. The adoption of hybrid nanofluids for thermal energy storage implementation fundamentally includes a variety of solar collectors, with 54% consisting of hybrid nanofluids. The present work emphasizes the potential of hybrid nanoparticles as heat transfer fluids in solar-generated thermal energy storage systems, paving the way for sustainable and efficiently utilized energy advancements. Further optimization of hybrid nanofluids, integration of enhanced phase change materials, and innovative approaches to improve the overall efficiency of solar energy storage systems are potential future areas.
