摘要：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 hydrogen storage to address these challenges. A multi-objective capacity optimization model is developed to minimize costs and carbon emissions, ensuring reliable hydrogen supply. To manage computational complexity, time variational autoencoder is applied to extract patterns from high-dimensional data for scenario generation and typical day selection. A refinery case study validates the system's capacity configuration. Pareto analysis reveals a tradeoff between costs and emissions, necessitating large-scale seasonal hydrogen storage to balance renewable energy fluctuations, while battery storage manages short-term fluctuations. Sensitivity analysis shows exceeding a 0.38 electrolyzer minimum load reduces the economic viability of renewable hydrogen production. The system achieves an LCOH of 2.28 USD/kg and annual carbon emissions of 361,139 tons, offering cost-effective and sustainable hydrogen production.
