Feasibility Study of Green Hydrogen Production from Geothermal Power Plant

Abstract

Fossil energy such as coal, gas, and oil are nonrenewable energy, and the use of fossil energy has negative effects in the environment. Global warming as one of the effects of the use of fossil energy encourages many countries to start using renewable energy. Geothermal energy and green hydrogen are an alternative energy to reduce the use of fossil energy. This study is to aim feasibility of using geothermal energy to produce green hydrogen. Simulation of the geothermal power plant system was carried out to evaluate the levelized cost of geothermal energy (LCOE) from Geothermal Power Plant (GPP). The results of the technical evaluation of the GPP, the LCOE are USD 7.52 c/kWh. Proton Exchange Membrane (PEM) technology is used to evaluate the price of green hydrogen production from geothermal power plants. The results of the technical and economic evaluation of GPP and PEM obtained a green hydrogen production price of USD 6.59 /KgH2. LCOH sensitivity evaluation obtained a value range of USD 4.96 /KgH2 to USD 8.23 /KgH2. The feasibility price of Green Hydrogen with IRR values of 12%, 14%, and 16%, are USD 8.14 /KgH2, USD 9.18 /KgH2, and USD 10.3 /KgH2. The NPV values of the 3 IRR scenarios are positive and PB for 9-11 years.
