  • Hydrogen Basics Electrolysis Production

    Hydrogen is evolved and collected at the cathode and oxygen is generated and collected at the anode. Limited quantities of hydrogen are currently produced from electrolysis, since electrolytic hydrogen is relatively expensive, with approximately 80 percent of the operating cost being the cost of electricity.

    Mar 29, 20180183;32;Introduction. The annual production of hydrogen is about 45 million metric tons and its consumption increases by 6% per year [7]. Today hydrogen is produced mainly from fossil fuels (mostly from natural gas) using the steam reforming process [7] and only 4% of hydrogen are produced by water electrolysis [8], [9].

    The electricity for electrolysis can come from any of the three energy sources. The cost of hydrogen production is an important issue. Hydrogen produced by steam reformation costs approximately three times the cost of natural gas per unit of energy produced. This means that if natural gas costs $6/million BTU, then hydrogen will be $18/million BTU.

  • Electrolysis of water

    OverviewHistoryPrincipleEquationsThermodynamicsElectrolyte selectionElectrolysis of water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current. The reaction has a standard potential of 1.23 V, meaning it ideally requires a potential difference of 1.23 volts to split water. This technique can be used to make hydrogen gas and breathable oxygen. However, as hydrogen is an important industrial commodity, by far most industrial methods produce hydrogen from natural gas instead, in the steam reforming process.Online Chat
