The assessment of nuclear hydrogen cogeneration system application for steel industry

Abstract

The assessment have been carried out on Nuclear Hydrogen Cogeneration System (NHCS) applications for the steel industry. The steel industry is an industry that requires large amounts of energy which has implications for large amounts of CO2 emissions to the environment. The NHCS application is expected to be able to reduce the use of fossil fuels which automatically can also reduce the rate of CO2 emissions. The objectives is to understand the process of the NHCS as a source of heat energy, hydrogen and the electricity that can be used for the steel industry. The method used in this study is the study of literature. The development of the process of reducing iron ore into iron sponges that allows hydrogen to be used as a reducing agent, opens the opportunity for the use of NHCS to replace fossil fuels as a conventional energy source. NHCS is a high temperature nuclear reactor based cogeneration system as a source of energy. NHCS is able to provide large amounts of heat, electricity and hydrogen energy. The heat output of High Temperature Gas-cooled Reactor (HTGR) at high temperatures is used to produce hydrogen, and is used as a heat source for shaft furnaces. While electrical energy is used for energy sources in electric arc furnaces. The replacement of conventional technology based on fossil fuels with the NHCS system is expected to be able to save on the use of fossil fuels, which will have implications for the significant reduction in the rate of CO2 emissions.
