Cost Analysis of Nuclear Hydrogen Production Using IAEA-HEEP 4 Software

Abstract Hydrogen is a commercially important element. Basically, there are several methods of hydrogen production that have been used, such as Steam Methane Reforming (SMR), High Temperature Electrolysis (HTSE), and thermochemical cycles, like Sulphur-Iodine (SI). Among these methods, SMR the most widely used for large-scale production, with conversion efficiency between 74–85% it has in some fertilizer industries Indonesia. reforming method to convert alkane (natural gas) compounds carbon dioxide (synthetic by adding moisture at high pressure temperature (35-40 bar; 800-900°C). These technologies can be coupled different nuclear reactors based on heat required process. The Gas-cooled Reactor (HTGR) using helium coolant, outlet (900°C), so potentially supply process coal liquefaction/gasification or other industrial processes requiring heat. cost from influenced range technical economic factors. fuel component natural gas needed replaced power plant (NPP) operating cogeneration mode (i.e. simultaneous producing electric heat), hence contributing reduction In method, costs largest component, accounting 45% 75% costs. Therefore, opportune assess economics evaluation done IAEA HEEP-4 Software. results comprise break up 2 cases, coupling with: (1) HTGRs 170 MWth/unit; (2) 1 HTGR 600 MWth/unit. highly depend scale NPP energy source indicated Unit600 MWth (Case 2) lower value (1.72 US$/kgH ), than obtained when units each (case 1) considered (2.72 ).
