About This Topic

Geothermal systems are found in a range of geological settings and each of the different types has distinct characteristics which may be reflected in the superficial features of these systems and the chemistry of fluids. The geothermal exploration could minimize risks related to resource temperature, depth, productivity and sustainability prior to drilling. The surveying techniques used may include surface studies (active surface features, etc.), geothermometry (fluid and soil sampling) and geophysical surveying (gravity, ER, magnetotelluric, seismic, temperature gradient, etc.). 
The estimation of reservoir temperatures is a major goal in geothermal exploration. Geothermometric calculations were used in order to assess the possible temperatures that may allow the exploitation of reservoirs. Chemical geothermometers are based on temperature dependent water-rock equilibrium, and give the last temperature of water-rock equilibrium attained in the aquifer. Nonetheless, the application of some geothermometers to mixed waters or partially equilibrated waters may produce poor results. Furthermore, the evaluation of thermal energy potential may be estimated by using mathematical models, which resolves heat, flow and mass transport equations in order to estimate the efficiency of geothermal applications. At final stage of the geothermal exploration begins the test drilling in order to demonstrate the feasibility of commertial production.
Flooded underground mines also may constitute a potential geothermal resource for low-temperature uses, or even for electricity production, if the reservoir reaches a sufficiently high temperature. The closure of deep abandoned mines involve the cessation of the expensive pumping systems and the progressive mine flooding and groundwater rebound may cause the transport of contaminants and energy. In these cases, mine waters may be a source of renewable energy and their hydrogeochemistry may be useful to determine the origin and nature of fluids. Thus, the use of mine water for geothermal purposes may provide an innovative opportunity to extract low-grade geothermal energy.
The conversion of geothermal energy into electrical energy may require the use of traditional power plants: direct dry-steam, flash steam and binary plants. The study of advances systems (super-critical fluids, etc.) may be of great interest for future geothermal exploitation.

Submission

Manuscripts should be submitted online at http://www.lidsen.com/account-login by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website. Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. Guidelines for authors and other relevant information for submission of manuscripts are available on the Instructions for Authors page. Journal of Energy and Power Technology is an international peer-reviewed Open Access monthly journal published by LIDSEN. Please visit the Instructions for Authors page before submitting a manuscript.
