ABSTRACT
PRELIMINARY STUDY ON HYDROGEN PRODUCTION PROCESS BY APPLYING VHTR REACTOR COGENERATION CONCEPT. Increasing demand on clean energy quantitatively triggers the development of the renewable energy systems, which have to fulfill several criteria, such as abundant, safe and sustainable. As an energy carrier, hydrogen have been more researched even used as a settled energy generation as well as movable energy generation likely used in transportation. However, the proper and economically hydrogen production process still more necessary to be assessed and researched. There are three methods underlying the hydrogen production processes: water electrolysis, steam reforming of methane, and sulfur-iodine cycle. The energy resource necessities to the hydrogen production process supplied by fossil fuel combustion, resulting in the total efficiency are decreased. This paper explains the assessment of feasibility of several hydrogen production processes using nuclear energy. As a nuclear energy resource, the very high temperature reactor (VHTR) is used. VHTR is one of the six generation IV reactor concepts. The assessment are stressed in the comparison of the advantage and disadvantage for each hydrogen production process coupled with the reactor system of the VHTR as the concept of cogeneration, and the comparison of the efficiency of each process. The result shows that VHTR reactor cogeneration concept combined with sulfur-iodine cycle process become good alternative for hydrogen production installation.
