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.
