Abstract The refining industry's substantial hydrogen demand relies on high‐carbon‐emission production methods, facing dual challenges of reducing costs and achieving net‐zero emissions. This study proposes a renewable energy‐powered water electrolysis system integrated with seasonal storage to address these challenges. A multi‐objective capacity optimization model is developed minimize carbon emissions, ensuring reliable supply. To manage computational complexity, time variational autoencoder applied extract patterns from high‐dimensional data for scenario generation typical day selection. refinery case validates the system's configuration. Pareto analysis reveals tradeoff between necessitating large‐scale balance energy fluctuations, while battery manages short‐term fluctuations. Sensitivity shows exceeding 0.38 electrolyzer minimum load reduces economic viability production. achieves an LCOH 2.28 USD/kg annual emissions 361,139 tons, offering cost‐effective sustainable
