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.

The present study investigates a process for the selective production of hydrogen from the catalytic decomposition of formic acid in the presence of iridium and iridium–palladium nanoparticles under various conditions. It was found that a loading of 1 wt.% of 2% palladium in the presence of 1% iridium over activated charcoal led to a 43% conversion of formic acid to hydrogen at room temperature after 4 h. Increasing the temperature to 60 °C led to further decomposition and an improvement in conversion yield to 63%. Dilution of formic acid from 0.5 to 0.2 M improved the decomposition, reaching conversion to 81%. The reported process could potentially be used in commercial applications.
