The use of glycerol in particular is motivated … catalysts led to a hydrogen-rich gas phase. However, a good potential activity with high production of hydrogen and low …

As part of Pilot Project of KIP of CAS, a feasibility study of hydrogen production system using biomass residues is … catalyst cost are the two most important factors to influence hydrogen production cost. …

dynamic behaviour of hydrogen fuel cells in automotive applications. The study was conducted on a dynamic test bench able to …

We compare two models to determine the size of grid units and dispatch in a wind-diesel power system with hydrogen … costs, the hydrogen storage-conversion system is excluded from the solutions, so the interesting operation rules associated … with the option of harvesting do not arise. However, the costs of hydrogen storage technologies are decreasing with …

The paper evaluates and discusses the combustion characteristics of electrolytically produced stoichiometric hydrogen … of a hydrogen-oxygen fuelled engine. Maximum combustion pressures are investigated and compared to theoretical …

The effect of the amount of hydrogen/ethyl alcohol addition on the performance and pollutant emission of a four … improved when operating the gasoline spark ignition engine with dual addition of hydrogen and ethyl alcohol. The important … power of hydrogen-supplemented engine. An equation has been derived from experimental data to specify the least quantity of …

water flow rate on hydrogen production and boron oxide gasification were studied at different furnace set point temperatures … and water flow rates. The produced hydrogen was measured by inline gas chromatography. Results show that the hydrogen … production rate increased by increasing the reaction temperature and water flow rate. The range of hydrogen production efficiency …
