Investigation of Sour Natural Gas Decomposition in a Nozzle-type Solar Reactor for Hydrogen Production

Analysis of Solar Thermochemical Water-Splitting Cycles for Hydrogen Production

Approach • Review all published papers, reports, patents, etc. in the past 25+ years that relate to thermochemical water-splitting cycles, in general, and solar driven cycles, in particular. • Use FactSageTM program to perform chemical equilibrium calculations. • Employ HYSYS/ASPEN Plus chemical process simulation (CPS) program for developing process flowsheet, process analyses and optimization...

Thermochemical solar hydrogen generation.

Solar direct, indirect and hybrid thermochemical processes are presented for the generation of hydrogen and compared to alternate solar hydrogen processes. A hybrid solar thermal/electrochemical process combines efficient photovoltaics and concentrated excess sub-bandgap heat into highly efficient elevated temperature solar electrolysis of water and generation of H2 fuel utilizing the thermodyn...

One-Dimensional Electrolyzer Modeling and System Sizing for Solar Hydrogen Production: an Economic Approach

In this paper, a solar based hydrogen production in the city of Tehran, the capital of Iran is simulated and the cost of produced hydrogen is evaluated. Local solar power profile is obtained using TRNSYS software for a typical parking station in Tehran. The generated electricity is used to supply power to a Proton Exchange Membrane (PEM) electrolyzer for hydrogen production. Dynamic nature of s...
