Geothermal energy is both a clean and sustainable energy source that contributes to economic growth (GDP) and environmentally friendly, as it releases much less harmful greenhouse gas (GHG) emissions than fossil fuels. This study presents a novel perspective by examining the dynamic impact of...

"Jahrhundertaufgaben" erfordern langfristige strategische Ansätze. Photovoltaikfreiflächenanlagen (PVA) oder auch Windkraftanlagen können für ehemalige gewerbliche oder militärische Flächen eine Alternative sein, aber entsprechende Ansätze sind nicht ausreichend, und die finanziellen...

Investment in deep geothermal heating (DGH) plants is hindered by the risks born by geological and market uncertainties. However, various flexibility options inherent to the development process, such as the option to abandon or defer, could partly mitigate these risks. To account for managerial...

Proper management of geothermal data is essential to the long-term development of geothermal resources at economically attractive costs. Even after a particulargeothermal resource has come on stream, the data gathered in the process may be useful in the development of other projects-if they are...

Innovative technologies in the field of geothermal energy focus on three areas: (i) resource assessment, (ii) resource development, and (iii) resource utilisation and management for electricity, heat supply and mineral extraction (lithium). They include increased electric power system...

The affordability and availability of water and energy have a huge impact on food production. Research has shown that there exists a direct and indirect link between power production and clean water generation. Hence the inclusion/importance given to the energy-water-food (EWF) nexus in the...

Social visions to replace fossil fuels with renewable energy sources have motivated unprecedented growth in global renewable energy manufacturing. Previous literature shows that people committed to realizing such visions have difficulties reconciling with the negative social-ecological impacts...

The use of new energy sources, including geothermal energy, is expanding rapidly in the world, and this energy is a good alternative to fossil fuels. In the present study, a combined power generation system (combined instantaneous evaporation cycle with supercritical carbon dioxide recovery...

Highlights● A review of ages of granite emplacement is reported● Low temperature thermochronology as a new tool for geothermal exploration● Apatite fission track data reveal buried magmatic intrusions● The Mid-Tuscany Metamorphic Ridge is a promising exploration target

Advanced iron boride protective coatings on carbon steels were tested and evaluated, for the first time, in actual corrosion conditions in the geothermal Rittershoffen and Soultz-sous-Forets sites (France) with positive results. Moreover, large size boronized spools demonstrated high performance...

The working fluid in geothermal wells often contains naturally occurring CO2. In an aqueous environment, CO2 forms carbonic acid and subsequently reacts with the binding components of cement, resulting in the loss of strength and early failure. Well cement formulations containing hydroxyapatite...

CO2-Plume Geothermal (CPG) technologies are geothermal power systems that use geologically stored CO2 as the subsurface heat extraction fluid to generate renewable energy. CPG technologies can support variable wind and solar energy technologies by providing dispatchable power, while Flexible CPG...

Achieving global goals for access to energy and mitigation of climate change will require a quadrupling of present levels of solar photovoltaic (PV), a multiplication by nine of the wind power generation and a doubling of the geothermal power generation in the developing world by 2025. To reach...

Geothermal energy has a significant role to play in the global transition to renewable and low-carbon energy systems because of its ability to supply steady and flexible electricity particularly for baseload demand because of its cost competitiveness compared to fossil fuel energy options....

Türkiye has substantial geothermal potential, and the country's government is committed to exploiting it, both for economic reasons and to meet its obligations as a signatory of the Paris Agreement on Climate Change. Türkiye has more than 400 known geothermal fields in 63 different provinces....

This article examines how rural roads relate to differences in livelihood patterns, attitudes toward social change, and land disputes in Baringo, Kenya. Although their direct use is limited for many residents, roads have a highly differentiating impact. While some households orientate themselves...

Determining geothermal target area priorities benefits overall planning of geothermal resource development. This study investigated five geothermal resource target areas in the Songyuan area of China by developing and applying an improved analytic hierarchy process to four factors: water...

Carbon dioxide (CO2) emission factors from Turkish geothermal plants have been measured in the 400 to 1,300 gram per kilowatt-hour (g per kWh) range, significantly higher than the reported global average (121 g per kWh). The good news is that despite these unusually high initial emission factors...

Purpose This paper aims to conduct a detailed analysis of the industrial practices currently being used in the geothermal energy industry and to determine whether they are contributing to any limitations. A HAZOP-based upgradation model for improvement in existing industrial practices is...

The growing concern about decarbonization of the energy production system led to the use of Renewable Energy Sources (RES). However, RES has the drawback of being inherently intermittent and lack controllability, placing limitations on their use. To avoid such limitations, the exploitation of a...

Geothermal energy has significant untapped potential for both electrical and direct-use applications in the EU. Currently, 'traditional' hydrothermal applications are most common for electricity production, but if EGS technology is proven the technical potential increases significantly. The...
