Electrolyzers working under pressure present an increase in specific energy demand for the dissociation of water into hydrogen and oxygen. However, energy savings are expected in global terms of plant when hydrogen is produced at high pressures, as a result of energy savings obtained in the subsequent compressions of gaseous hydrogen. In a context, wherein the standard of hydrogen refuelling stations for mobile applications will be compressed at 700 bar, the use of pressurized electrolyzers presents especial interest. This work assesses the energy needed to produce hydrogen at 900 bar by using a high pressure PEM electrolyzer working at operating pressures ranging from 1 bar to 130 bar, followed by four stages of compression with intercooling. The results of this work show that there are energy savings under specific conditions. | |
