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...

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 demand from a geothermal modeler’s point of view has grown beyond the features provided by existing geothermal reservoir simulators. Existing packages are either built on code which is over 30 years old (e.g. TOUGH2) or is proprietary (e.g. TETRAD); in both cases adapting the code to include new features required for simulating a developed geothermal field is challenging. In particular, the...

We present the results of GPS measurement and modeling of active crustal deformation and its spatial relationship to active geothermal systems in the northern Walker Lane. Using a block modeling method we use the GPS data to estimate the slip rate and style on faults in our study area. Our results show that there is a spatial correlation between zones of high dextral slip rate that also have a ...

A recently developed variational principle of virtual dissipation along with a new approach to the thermodynamics of open systems is applied to coupled mass and heat transfer in a porous solid containing a fluid. General differential field equations are derived directly from the variational principle. A general energy flux theorem is formulated. Vapor-liquid phase transition and capillary conde...
