Abstract: This study evaluates the performance of a Solar-Wind-Biomass Hybrid Renewable Energy System (SWB-HRES) optimized for Hoa Bac conditions. The system comprises a 15 kW solar panel, 9 kW wind turbine, 8.3 kW syngas generator, 20 kW electrolyzer, 24 kW converter, and a 1 kg hydrogen storage tank. It supplies 7,300 kWh/year of electricity and produces 1,183 kg/year of hydrogen. When integrated with a hydrogen production grid, the solar-biomass (SB-H2) configuration demonstrates superior economic and environmental performance, offering double the profit and half the payback period compared to the wind-biomass (WB-H2) option. The economic viability of hydrogen production matches that of grid electricity sales when hydrogen is priced at $4.5/kg (non-continuous engine operation) or $5/kg (intermittent operation). Incorporating biomass significantly reduces greenhouse gas emissions: while a solar-wind system without hydrogen production cuts 33 tons CO₂-eq/year, the solar-wind-biomass system with hydrogen production achieves a reduction of 217 tons CO₂-eq/year.
