ABSTRACT The motivation for this study stems from the global demand clean energy solutions and limitations of conventional fluids in hydrogen production systems. By exploring hybrid nanofluids, research aims to enhance efficiency sustainability solar‐thermal applications. An evacuated tube solar collector (ETSC) with a polymer electrolyte membrane (PEM) electrolyzer efficiently harnesses production. ETSC's vacuum design minimizes heat loss, providing consistent thermal performance. This system enables generation, reducing emissions. investigated integration an ETSC PEM organic Rankine cycle (ORC) efficient Water as working fluid circuit resulted lower rates, prompting introduction Al 2 O 3 SiO nanoparticles at 50:50 ratio form enhanced nanofluid. resulting various volume concentrations (0.5%, 1%, 1.5%, 2%) nanofluid were tested, yielding gains 13.22%, 21.37%, 30.38%, 48.52%, respectively, compared water. ORC by 12.29% 0.5 vol.%, 23.10% 1 34.15% 1.5 48.40% vol.%. produced maximum yield 3105.6 g, overall 71.3% 2156.7 g demonstrating significant performance enhancements achieved nanofluids. results demonstrated effectiveness nanofluids enhancing output, underscoring their importance promoting sustainable technologies.
