In the perspective of increasing the share of renewable energies to mitigate global warming and to respond to fossil resources depletion, the use of geothermal resources for the polygeneration of energy services has gained interest and is expected to know an important development in the future. Some of the major issues linked with the use of geothermal energy concern the increase of the efficie...

Hybrid solar and geothermal utilisation is a promising option for effective exploitation of renewable energy sources. Concentrated power (CSP) systems with preheating are acknowledged as an attractive solution, supercritical CO2 (SCO2) cycle adopted generation thanks to the favourable properties offered by working fluid. In order further improve overall performance such systems, organic Rankine...

At the Kakkonb geothermal area, Japan, a large Quaternary granitic body is dstributed below ca 2.5 km ckpth from the surface, associating with thick high-temperature contact me&amorphic zones in the overlying formations, and a meteoric-water-cbminated type hydrothermal system is developedat present time. During the 'Deep-seated Geothermal Resources Survey', WD-la well was drilled to 3729 m dept...
