The dynamical role of geothermal heating in abyssal circulation is reconsidered using three independent arguments. First, we show that a uniform geothermal heat flux close to the observed average (86.4mWm−2) supplies as much heat to near-bottom water as a diapycnal mixing rate of ∼10−4 m2 s−1 – the canonical value thought to be responsible for the magnitude of the present-day abyssal circulatio...

A new and economically attractive type of geothermal resource was recently discovered in the Krafla volcanic system, Iceland, consisting of supercritical water at 450 °C immediately above a 2-km deep magma body. Although utilizing such supercritical resources could multiply power production from geothermal wells, the abundance, location and size of similar resources are undefined. Here we prese...

Background After decades of research carried out in India by several government organizations, a decision has been taken to generate 1000 MW of electricity using geothermal energy by 2022. Geothermal energy is perceived as a hidden potential in the earth’s crust. The USA, Indonesia, Philippines, Italy, Mexico and Iceland are the leading nations in utilizing this potential. Research efforts in I...

Geographic Information System (GIS) was used as a decision-making tool to target potential geothermal power plant sites in Sabalan geothermal field, northwestern part of Iran. The aim of the study was to identify suitable areas to establish 55 MW geothermal power plants (GPP). After comprehensive study about required data for GPP site selection project, available data in the area on a regional ...

In Central Europe, the utilization of low enthalpy reservoirs for electricity production has not yet fully developed. Reliable technological experience will only be obtained from future projects. Currently, the utilization is still at an experimental stage and the failure of only a single project could easily have dramatic consequences for the continuation of other projects due to limited publi...

China is in geothermal According to latest statistical data , the number hot springs with in the country is over 2 700. If the hot water wells in basins and water in mines werc i t would be well over 4 I n recent years. progress in geothermal exploration and utilization has bcen made. Geothermal resources diflerent types are for diflerent purposes. The high temperature gcothermal resources the ...

The Las Tres Vírgenes (LTV) geothermal reservoir is a liquid-dominated resource located in the Baja California Peninsula (NW-Mexico) with a currently installed power capacity of 10 MWe. The sustainability of future electricity production at the LTV geothermal field raises concerns about the origin and hydraulic dynamics of exploited geothermal fluids. As part of the present study, water samples...

11 12 13 In this study, we report chemical and isotope data for 23 geothermal water samples collected in New Zealand 14 within the Taupo Volcanic Zone (TVZ). We analyzed major and trace elements including Li, B and Sr and their 15 isotopic compositions ( 7 Li,  11 B, 87 Sr/ 86 Sr) in high temperature geothermal waters collected from deep boreholes 16 in different geothermal fields (Ohaaki, Wa...

Europe is the world leader in geothermal direct use. Geothermal is used in 32 European countries mainly for space heating, bathing and balneotherapy, than for heating greenhouses, aquaculture, and industrial use. In a number of countries the development is based on waters exploited from deep wells. Some countries have been dynamically developing shallow geothermal based on heat pumps. Power gen...
