This study explores the biomass gasification potential for decentralized power generation in remote, off-grid areas with minimal environmental impact. Focusing on an integrated gasification system utilizing sacha inchi residues, the research evaluates its exergetic and exergoeconomic performance in generating 35 kW for a rural location in Santander, Colombia. Utilizing Aspen Plus software, detailed modeling is conducted to analyze mass, energy, and exergy flows across gas and solid streams, considering gasifier conditions and solid fuel composition. Optimal operation is identified at an equivalence ratio of 0.25, achieving a lower heating value of 6.126 MJ/kg, 100% carbon conversion efficiency, and 73.5% cold gas efficiency. Exergetic analysis highlights heat exchangers and the power generator as least efficient components (0.214% to 27.85%), while the gasifier, air blower, and cyclone exhibit superior efficiencies (82.85% to 96.13%). Exergoeconomic assessment reveals an energy cost of 10.25 USD/GJ, significantly lower than Colombian energy costs for equivalent power needs.
