“…Thermal pollution can also be caused by discharged hot water. In general, geothermal waters from power plants are re-injected into the geological units from which they were extracted to prevent environmental problems and to re-feed the reservoir (Baba and Sözbilir 2012; Shortall et al 2015;Bosnjakovıc et al 2019). Furthermore, GPPs have been using H 2 S reduction systems for the emitted steam since 1976 (Matek 2013).…”

The use of renewable energy is critical to the long-term development of global energy. Geothermal Power Plants (GPP) differ in the technology they use to convert the source to electricity (dual, single ash, double ash, back pressure, and dry steam) as well as the cooling technology they use (water-cooled and air-cooled). The environmental consequences vary depending on the conversion and cooling technology used. Environmental consequences of geothermal exploration, development, and energy generation includes land use and visual impacts, microclimatic impacts, impacts on ora-fauna and biodiversity, air emissions, water quality, soil pollution, noise, micro-earthquakes, induced seismicity, and subsidence. It can also have an impact on social and economic communities. As geothermal activity progresses from exploration to development and production, these effects become more signi cant. Before beginning geothermal energy activity, the positive and negative aspects of these effects should be considered. The number of GPPs in the Büyük Menderes Graben (BMG) geothermal area is increasing rapidly. According to the ndings, in order to reduce the environmental and social impacts of the GPPs in the BMG, resource conservation and development, production sustainability, and operational problems should be continuously monitored.

“…This condition has been described by Muraoka et al [10]; the tectonic, volcanic, and stratigraphic geology of the Bajawa area contains a collective cinder cone called the Bajawa Cone Complex. On January [11][12][13][14][15][16]2001, the phreatomagmatic eruption showed potential as a geothermal resource in the Indie Lika volcano, Flores Island [11]. This cinder cone is produced from volcanic processes, tectonic processes in the zone, representing the Bajawa fracture zone [10].…”

“…In practice, the gas effect can only be overcome by evacuating using a portion of the main vapor. The NCG released by geothermal power plants into the outside environment contains carbon dioxide, hydrogen sulfide, methane, and ammonia [16].…”

“…In addition, GPP also produces CO2 and CH4 emissions. In general, GPP's carbon emissions are lower than fossil fuel power plants such as coal or gas (14)(15)(16). However, although GPP has only about 400g CO2/kWh (depending on location and technology conversion) [21], it still has an impact on the environment and contributes to climate change [22].…”

The Mataloko geothermal system in Ngada-Flores Regency, East Nusa Tenggara, is located in three active volcanic mountains (Inerie, Ebulobo, and Inielika). The contribution of high levels of CH4 and exhaust emissions of SO2 due to its utilization as a geothermal power plant (GPP) impacts the environment. This study aims to analyze and spatially model the distribution and impact of SO2 and CH4 gas levels in the Mataloko GPP area. The quantitative descriptive method was used through direct measurement at gas wells and laboratory testing. The results showed a tendency to increase SO2 levels in the MT-4 gas-well with levels of 8.00 ppm exceeding the quality standard, which could disturb the environment in the Mataloko-GPP area. Impact of high SO2 will experience dry sediment because it is not combustible in the air, then it will drop slowly to be absorbed by soil and plants. Droplets of acid gas blown by the wind and left on trees and buildings are even inhaled into the breath. In addition, the advantages of model with surfer 12 software can help identify the distribution of SO2 and SO4 emissions in the generating area.

The use of renewable energy is critical to the long-term development of global energy. Geothermal Power Plants (GPP) differ in the technology they use to convert the source to electricity (dual, single flash, double flash, back pressure, and dry steam) as well as the cooling technology they use (water-cooled and air-cooled). The environmental consequences vary depending on the conversion and cooling technology used. Environmental consequences of geothermal exploration, development, and energy generation includes land use and visual impacts, microclimatic impacts, impacts on flora-fauna and biodiversity, air emissions, water quality, soil pollution, noise, micro-earthquakes, induced seismicity, and subsidence. It can also have an impact on social and economic communities. As geothermal activity progresses from exploration to development and production, these effects become more significant. Before beginning geothermal energy activity, the positive and negative aspects of these effects should be considered. The number of GPPs in the Büyük Menderes Graben (BMG) geothermal area is increasing rapidly. According to the findings, in order to reduce the environmental and social impacts of the GPPs in the BMG, resource conservation and development, production sustainability, and operational problems should be continuously monitored.
