This paper compares thermodynamic performance, through energy and exergy efficiencies, of the some renewable-based (e.g.geothermal) and non-renewable-based hydrogen production processes, namely: (1) steam methane reforming (SMR), (2) hybrid copperchlorine (Cu-Cl) supplied by geothermal heat and electricity from a geothermal power plant, (3) high temperature steam electrolysis (HTSE) supplied by geothermal heat and electricity from a geothermal power plant.These processes are essentially driven by two different sources such as fossil fuel and geothermal.The results show that energy and exergy efficiencies during hydrogen production range from 65-89% and 63-80% for the SMR.The efficiencies of geothermal-based hydrogen production processes seem to be a bit lower than that of SMR.However, these processes can drastically reduce the GHG emissions compared to non-renewable energy based ones, e.g., SMR process.
