The assessment of the rich geothermal energy sources
in some regions of our country enables domestic and renewable energy
production. At the same time, the availability of significant biomass waste
potentials in these regions is also a source of hydrogen gas production, an
energy carrier. As a result of the gasification of the biomass, high purity
hydrogen can be produced using the synthesis gas obtained. In this study,
geothermal and biomass energy resources are aimed to be evaluated together. A
power generation system integrated with hydrogen production from a
biomass-derived synthesis gas, which can be installed in the Manisa Alaşehir
region, which has geothermal resources, is modeled. For this, the synthesis gas
content was determined to be 3 kg/s. On this basis, the proposed system is
simulated using the Aspen HYSYS simulation software and the feasibility of the
system is investigated. As a result of simulation and analysis studies, 729 kWe
of electric energy can be generated for an established capacity using an
organic Rankine cycle designed with the hydrogen production system. Thus, some
of the energy consumed by the hydrogen production process can be met.
Furthermore, the remaining energy requirement can be achieved with the
installed geothermal power plant. The proposed system has a total internal
consumption of 14,886 kWe. The total power of Organic Rankine and geothermal
power cycles is 47,649 kWe. It is assessed that this work may contribute to
preliminary design studies of similar hybrid systems including biomass and
other renewable resources.
