This study aims to determine the most cost-effective approach for production of green hydrogen, a crucial element global decarbonization efforts despite its high costs. The primary research question addresses optimal and economically viable strategy hydrogen considering various scenarios technologies. Through comprehensive analysis eight scenarios, employs economic parameters such as net present value, minimum cost, payback period sensitivity analysis. is validated using established metrics real-world considerations ensure feasibility. results suggest that hybrid system combining solar photovoltaic (PV) with storage onshore wind turbines promising yielding cost $3.01 per kg an internal rate return (IRR) 5.04% 8-year period. These findings provide practical solution supporting transition sustainable energy sources. also highlights future potential integrating thermal (CSP) organic Rankine cycle (ORC) waste heat recovery in production. provides importance capacity factor, levelized capital expenditure discount influencing
