Optimization of Solar Thermo-Chemical Hydrogen Production Process

Abstract

Based on the integration of different systems and the comprehensive step utilization of energy, the system of hydrogen production by biomass gasification in supercritical water using concentrated solar energy has been coupled by using the combination of solar and biomass as an energy source. As a model compound of biomass, glucose was gasified in supercritical water at 25MPa and 873K, whether there is pre-heater water in the hydrogen production system was compared by the way of thermodynamic analysis. The results show that energy and exergy efficiency is high in the hydrogen production system with pre-heat water.
