The transition toward sustainable and carbon-neutral energy systems has motivated the exploration of integrated renewable energy solutions capable of producing electricity, cooling, and hydrogen simultaneously. This study investigates and optimizes various thermodynamic configurations based on biomass gasification to achieve multi-product energy generation. Several system arrangements combining gasification with power cycles, cooling systems, and hydrogen production units are modeled and analyzed using energy, exergy, and exergoeconomic methods. Multi-objective optimization is performed to identify the best configuration that maximizes energy and exergy efficiencies while minimizing production costs and environmental impact. Parametric studies reveal the influence of key design and operational parameters, such as gasifier temperature, biomass feed rate, and cycle pressures, on system performance. The optimized configuration demonstrates a significant improvement in overall efficiency, hydrogen yield, and electricity generation, providing a technically and economically feasible pathway for sustainable energy production. The results offer valuable insights for the design and implementation of advanced biomass-based hybrid energy systems capable of meeting growing energy and environmental demands.
