Effects of CuO/Al2O3/Water-WO3 nanomaterials on NETZERO energy/emission-based hydrogen generation

•Net Zero Emission /Energy utilized for Hydrogen Generation with PTC and Nanofluids.•Neglected viscosity changes by 0.02 wt% concentration of CuO, Al2O3, and Water-WO3.•High thermal efficiency recorded by CuO Nanofluid as 79% and Exergy was 7.2%.•Net power output of the absorber system is 897 KW with CuO Nanofluid.•Average rate of hydrogen generation is roughly 0.031 kg/s with CuO Nanofluid.•By using Al2O3 & WO3 Nanofluids achieved were 72% & 68% respectively.
