A review of geothermal energy-driven hydrogen production systems

This paper presents a review of hydrogen production systems using geothermal energy, showing the importance and potential this technology in addition to main obstacles facing domain. The effect several parameters was taken into consideration, such as fluid temperature, water electrolysis working fluid, type power cycle. different types plants were also compared, namely, flash, binary, flash-binary, recuperative, regenerative, organic Rankine flash cycles. study covers wide range investigations regarding rate, cost, energetic efficiency, exergetic electricity generated. Hydrogen rate is one most important mentioned which it found vary from 5.439 kg/h 13958 kg/h. Multigeneration have shown great enhance overall system’s leading reduced costs. integration another energy source be interesting geothermal-driven systems. would promote adoption multigeneration system well increasing fluid’s temperature before entering
