The noncondensable gases in most geothermal resources include CO2 and smaller amounts of other gases. Currently, the worldwide geothermal power is a small sector within the energy industry, and CO2 emissions related to the utilisation of geothermal resources are consequently small. In some countries, however, such as Turkey and Iceland, geothermal energy production contributes significantly to their energy budget, and their CO2 emissions are relatively significant. SUCCEED is a targeted innovation and research project, which aims to investigate the reinjection of CO2 produced at geothermal power production sites and develop, test, and demonstrate at field scale innovative measurement, monitoring and verification (MMV) technologies that can be used in most CO2geological storage projects. The project is carried out at two operating geothermal energy production sites, the Kizildere geothermal field in Turkey and the CarbFix project site at the Hellishei eth i geothermal field in Iceland. Together with a brief description of the project, this paper presents the details of the two field sites and the progress made in seismic velocity characterisation and modelling relevant to the Kizildere geothermal field in Turkey

Geochemical characterization of geothermal systems in western Anatolia (Turkey): implications for CO2 trapping mechanisms in prospective CO2-EGS sites
Elidemir, Sanem; Güleç, Nilgün Türkan (2018-02-01)
Geological storage of CO2 is currently regarded as one of the major strategies to mitigate the increasing CO2 concentrations in the atmosphere due to anthropogenic emissions from large-scale point sources. Enhanced geothermal systems (EGS) are a novel concept in which CO2 is used as a working fluid to increase energy recovery, combined with its subsurface storage. In this study, the geothermal systems of western Anatolia are considered as potential sites for EGS, and the published hydrogeochemical data rele...
Numerical simulations of gas production from Class 1 hydrate and Class 3 hydrate in the Nile Delta of the Mediterranean Sea
MEREY, ŞÜKRÜ; Longinos, Sotirios Nik (Elsevier BV, 2018-04-01)
Gas hydrate reservoirs are considered as near-future energy resources in the world. As well as the many places in the world, there is also gas hydrate potential in the Mediterranean Sea. In this study, by using the literature data, it was aimed to understand whether the Mediterranean Sea includes necessary parameters for producible gas hydrate reservoirs. It was shown that the Mediterranean Sea contains all of these parameters (source gas, appropriate pressure and temperature, coarse sand potential, etc.). ...
Geochemical modeling of CO2-water-rock interaction in indonesian geothermal fields for a possible future carbon capture and storage project
Utomo, Gagas Pambudi; Yılmaz, Koray K.; Department of Geological Engineering (2019)
The rise of CO2 concentration in Earth’s atmosphere from anthropogenic emissions is the main cause of global warming and climate change. Carbon Capture and Storage (CCS) is considered as an effective method to reduce such emission. CCS can be performed in various sites including geothermal reservoirs. This study is concerned with geochemical modeling of CO2-water-rock interaction for a possible future CCS project in Indonesian geothermal fields, namely Ungaran, Baturaden, Dieng and Awibengkok. The modeling ...
Fluid-CO2 injection impact in a geothermal reservoir: Evaluation with 3-D reactive transport modeling
AKIN, TAYLAN; Baser, Ali; Saracoglu, Onder; Akın, Serhat (2022-01-01)
Geothermal energy is commonly recognized as an environmentally friendly source of energy. However, geothermal fluids have unusually high CO2 content, particularly, in carbonated geothermal reservoirs. An efficient method to mitigate the CO2 emissions of geothermal power plants is to re-inject the captured CO2 with the effluent fluid to mineralize mainly into calcite under reservoir conditions (e.g., reservoir temperatures ranging from 200 to 220 degrees C). One of the major concerns about the re-injection o...
Investigation of Turkey's carbon dioxide problem by numerical modeling
Can, Ali; Tokdemir, Turgut; Department of Engineering Sciences (2006)
CO2 emission is very important, because it is responsible for about 60% of the "Greenhouse Effect". The major objectives of this study were to prepare a CO2 emission inventory of Turkey based on districts and provinces by using the fuel consumption data with respect to its sources, to find the CO2 uptake rate of forests in Turkey based on provinces and districts, and to estimate the ground level concentration of CO2 across Turkey using U.S. EPA's ISCLT3 model for the preparation of ground level concentratio...
