In this study seasonal changes in the geochemical and stable isotope compositions of Hisaralan thermal waters in Simav Graben, western Turkey, were investigated with regards to a variety of mineral-water interactions and mixing processes. The Hisaralan and Emendere geothermal waters, with temperatures of up to 99 °C, were mostly of Na-HCO3 and Ca-HCO3 types. The δ18O and δ2 H values of the Hisaralan waters ranged from –9.32‰ to –8.73‰ and –65.02‰ to –61.10‰, with maximum seasonal differences of 0.3‰ and 1.8‰. The Emendere waters were represented by a more positive range of δ2 H values (–54.

Before this earthquake, water resources were monitored in the areas of Bayraklı, Gülbahçe, and Seferihisar. For this purpose, 10 groundwater monitoring wells were drilled in the Bayraklı area, where groundwater level, temperature, and electrical conductivity changes were monitored at 1-h intervals in 5 wells. Besides physical parameters such as groundwater levels, temperatures and electrical conductivities, hydrogeochemical cations, and anions measured in the study area. Change in the groundwater levels was observed before, during, and after the Samos earthquake.

This paper aimed to determine the grey water footprint (GWF) of geothermal water resources and to investigate the effect of biochar adsorption on grey water footprint in Southeastern Turkey. In this paper, GWF has been calculated in terms of iron (Fe), arsenic (As), manganese (Mn), boron (B), and chrome (Cr) concentrations for fifteen observation geothermal resources located in Southeastern Anatolia Region. In this study, a new approach based on the GWF was developed in order to determine the geothermal water pollution.

Lithium (Li) is the lightest metal, has unique physicochemical properties and is the main component of lithium-ion batteries. Rechargeable lithium-ion batteries play a very important role in maximizing the performance of electric devices and vehicles. It is predicted that the metal and mineral demand for lithium-ion batteries will increase 56 times by 2050. In order to meet the increasing demand, in addition to known methods, lithium recovery from geothermal waters has become a very popular research subject.

Although the western Anatolian region is a foci for hydrothermal systems, this region has several high heat-generating granitic intrusive bodies that qualify to be candidates for enhanced geothermal systems (EGS). Considering the future energy requirement, carbon dioxide emissions reduction strategies, food, and water security issues, these granites appear to be the future clean energy source for the country. One such granite intrusive is located in the Kestanbol area in the western Anatolian region.

Batch-type laboratory reactivity experiments and mo delling of hydrogeochemical interactions of a granite-scCO2-water system were conducted at 100 °C and 10 MPa in order to evaluate the geochemical and mineralogical responses of the granite to long-term reaction. The laboratory reactivity tests were conducted for a to t l duration of 70 days, and the continued hydrogeochemical interactions for up to 210 days we re determined by geochemical simulations.

Kestanbol geothermal field is located in northwestern Turkey and is one of the highest temperature geothermal fields in the Biga Peninsula. In this study, one geothermal well, two geothermal springs, and two cold springs were monitored for one year in Kestanbol geothermal field to determine hydrogeochemical and isotopic characteristics. Additionally, any possible relationship between seismic activity and variations in the hydrochemistry of geothermal water was investigated.

To improve the utilization rate of hot dry rock resources, it is necessary to recover the energy of geothermal tailwater and improve the net output work. An improved ammonia-water power cycle is proposed based on the Kalina cycle. Taking the geothermal parameters of the Husavik Power Plant in Iceland as the prototype (the water temperature of the geothermal well is 122°C, and the tailwater temperature is 80°C), the numerical simulation of the modified Kalina cycle is carried out by using Engineering Equation Solver software.

Balçova-Narlıdere Geothermal Field (BNGF) hosts the largest geothermal district heating system of Turkey and several geothermal wells used for district heating and thermal tourism activities. This study assesses the use of BNGF geothermal fluid for agricultural activities. The spent geothermal brine was treated using nanofiltration and reverse osmosis membranes on a pilot-scale membrane test system. The qualities of the product were evaluated in terms of agricultural irrigation integrated with the implemented innovative wireless sensor network.

This research explored the thermal property of a warm spring in Nigeria as a potential source of thermal electricity generation. Ikogosi warm spring is located in Ekiti State, Nigeria. The spring consists of cool and warm water flowing at a very close proximity while each maintains its thermal property. For a long time ago, the water from the spring has been used as therapeutic cure of some diseases such as rheumatism and guinea-worm in addition to its tourism while other people used the water as battery electrolyte.

Geothermal ventilation provides a better alternative in securing the energy crises. Geothermal energy is a heat contained within the earth that generates geological phenomena on a planetary scale. It is not only available in the form of volcanoes, hot water stream but, whole earth acts as a source of geothermal energy for 365 days and all season of year. There are three basic components of geothermal heating pump system (GHPS); ground loop, geothermal heat pump and distribution system.

The Mount Sabalan district is regarded as the best place to investigate geothermal activities in northwest Iran. Since the last episode of volcanic activity in the Plio-Quaternary time, hot springs and surficial steams as conspicuous manifestation of geothermal activities have appeared around the slopes of Mount Sabalan.

Renewable energy technologies—including solar, wind, biomass, geothermal, and hydropower—are in many ways attractive to policy makers who must address these market disruptions and the economic and social strife they can create. Renewable energy technologies are advantageous because they are immune to price shocks from fuel supply constraints and cartel pricing. Furthermore, renewable energy resources are much more environmentally benign than their conventional counterparts, such as coal, nuclear, and petroleum products.

Renewable Energy is energy generated from natural resources - such as sunlight, wind, rain, tides and geothermal heat - which are naturally replenished. In 2008, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood burning. Hydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation), followed by solar hot water/heating, which contributed with 1.3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.
