It is well known that power recovery from liquid geothermal brines could be considerably increased by means of efficient two-phase expanders. Hitherto proposals for them have not been economically viable either due to the low adiabatic efficiencies of the expanders or their relatively high manufacturing cost. It has already been reported how, as a result of a long term research and development ...

Just because of burning fossil fuels and the fact that renewable energy sources (solar, wind, hydraulic, geothermal, biomass, tidal, wave etc.) have not become widespread globally, many parallel environmental problems such as global warming, climate change carbon emissions been emerged. In present study, two different orange cultivars (Valencia Washington Navel) were dried under air-convective ...

Renewable energy is seen as the future source for meeting the world’s growing demand, with geothermal offering a constant and independent supply. Tapping geothermal energy is not always straightforward as deep drilling is required in order to access this high -temperature resource. Geothermal drilling is expensive and is financed by the operator (usually districts or state representatives) with...

It is well corroborated that the earth is relentlessly bubbling inside since its birth and traversing continuously through a geological change. The source of this dynamism is the heat stored inside i.e. the geothermal energy, which is believed to be the product of mainly the decay of natural radio-isotopes in the crust and mantle, and in the core of earth. This heat exerts pressure towards the ...

Growth in geothermal power production in the Hengill area of Iceland, and a need for environmental impact studies that look hundreds of years ahead, has resulted in new challenges for numerical model developers. An existing, large-scale, iTOUGH2based 3-D reservoir model of the Hengill volcano has recently been recalibrated and used to study the impact of 400 MWe and 700 MWt cogenerations in two...

Introduction High enthalpy geothermal systems have been harnessed for electrical power generation for over a 100 years. While the classification scheme for low, medium, and high enthalpy systems varies for different authors (Axelsson and Gunnlaugsson 2000; Benderitter and Cormy 1990; Hochstein 1990; Kaya et al. 2011; Muffler and Cataldi 1978; Nicholson 1993), reservoir temperatures above 150–22...

Generally, greenhouses are high energy-consuming, sometimes accounting for 50% of the cost greenhouse production. Geothermal energy plays a very important role in maintaining desired temperature and reducing consumption. This work deals with project hybrid heating plant (97% geothermal 3% gas-condensing boiler) innovative Plant Phenotyping Greenhouse at University Campus Grugliasco (few km West...

Geothermal energy is a clean, green renewable resource, which can be utilized for power generation, heating, cooling, and could effectively replace oil, gas, and coal. In recent years, oil companies have put more efforts into exploiting and utilizing geothermal energy with advanced technologies for heat-tracing oil gathering and transportation, central heating, etc., which has not only reduced ...
