A process simulation-based study was done to evaluate the integration of steam gasification and chemical looping combustion to produce hydrogen while generating power from algae (Fucus serratus). The process simulation was done using ASPEN Plus software package. The integrated system consists of drying, steam gasification, chemical looping combustion, and power generation. Enhanced process integration technology was adopted to maximize the heat circulation throughout the system. Chemical looping combustion used in this study consists of fuel, steam, and air reactors. Iron oxide was utilized as the circulated oxygen carrier in the chemical looping system which was reduced and oxidized through the reactors. The performance of the integrated system was evaluated under different steam-to-biomass ratios during gasification and operational pressures of the chemical looping combustion. The simulation result shows that the integrated system had a relatively high total efficiency (about 72%) which consisted of hydrogen production and power generation efficiencies of about 57% and 15%, respectively.
