Geothermal Articles

Since the early twentieth century, geothermal energy has been used to produce electricity. In the 1980’s and 90’s, rapid expansion in the demand for geothermal energy put pressure on suppliers to reduce costs and increase efficiencies. Now geothermal energy production is becoming a common practice around the globe. One of the largest energy companies in Turkey is blazing the ...

January 9, 2017 — At 2:46 p.m. local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1 magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the back-up emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant complex, causing a series of ...

University of Bologna researchers carried out an investigation of the thermal properties of the coastal aquifer at Ravenna Italy in order to evaluate its geothermal potential for residential heating. As part of that investigation, they measured the water temperature versus depth at 56 piezometers. EnviroInsite was then utilized to establish the relationship of water temperature with land use, ...

Earth, sun and atmosphere are the ultimate energy resources. In addition to fossil fuels, earth radiates over 45 TW geothermal energy. Sun radiates about 89 PW energy to earth's surface. Lunar gravity supplies over 100 GW tidal ocean energy. Accessible energy from geothermal, solar, tides, waves and winds is far more than our current 17 TW energy demand, yet there are new avenues like tornadoes ...

By drilling using a specially designed hydride carbide (melting point: 1,365°C) drill, we can drill the earth's crust to about 5 to 40 km to reach temperatures of 700 to 1,000°C, with minimum cost of the drill and drilling technology. Further, we can extract energy by pouring in water on an inserted carbide alloy vessel into the drilled well and bringing out as steam to drive the turbines. By ...

In this study, exergy and exergoeconomic analyses of the Dora II geothermal power plant (DGPP) with 9.5 MW net power output are carried out by using real thermodynamic and cost data. The exergetic efficiency of this plant is calculated to be 29.6%. The highest exergy destruction rate among the DGPP components occurs in the cooling towers followed by the turbines, vaporisers, preheaters and pumps. ...
