China's dual carbon goals and rural energy poverty in western provinces necessitate cost-effective autonomous energy solutions where grid extension remains economically unfeasible. This study addresses the economic optimization challenge of off-grid hydrogen energy systems serving remote communities in Qinghai, Tibet, Inner Mongolia, and Xinjiang, where diesel generation costs exceed $0.30/kWh including transportation. We develop an economic-centered energy management framework integrating solar photovoltaics with hydrogen production, storage, and fuel cell generation to minimize total system costs while ensuring reliable energy supply.The research presents a techno-economic optimization model analyzing capital expenditure, operational costs, component replacement schedules, and system degradation economics across 20-year project lifetimes. A predictive energy management strategy employing machine learning forecasting and dynamic control algorithms optimizes production-consumption patterns to reduce equipment cycling costs and maximize revenue from energy sales. Economic feasibility analysis under Chinese market conditions reveals levelized cost of energy (LCOE) of $0.19–0.24/kWh for hydrogen-integrated systems, achieving cost parity with diesel alternatives while eliminating fuel supply chain vulnerabilities.Cost-benefit analysis demonstrates: (1) optimized energy management reduces annual equipment replacement costs by $4800 through extended component lifespans, (2) thermal energy recovery decreases hydrogen production costs by 13.2%, saving $6400 annually in operational expenditures, (3) integrated system efficiency improvements lower total energy costs by 18.7% compared to conventional control strategies, and (4) net present value reaches $58,000 over project lifetime with internal rate of return of 11.3% under current subsidy frameworks. This study suggests establishing hydrogen equipment subsidies at 35–45% of capital costs for remote installations, implementing differentiated feed-in tariffs ($0.10–0.15/kWh) for off-grid renewable hydrogen systems, creating low-interest financing mechanisms (2–3% annual rate) for rural energy cooperatives, and developing technical certification standards for economic energy management systems. These interventions can accelerate deployment of 500–800 MW hydrogen capacity in underserved regions by 2030, benefiting 2.3 million rural residents while reducing diesel consumption by 180,000 tons annually.
