The present study aimed at ranking and selecting the superior geothermal project for hydrogen production in 14 provinces of Iran using a multi-objective optimization fuzzy hybrid approach through analyzing the ratio (fuzzy Moora) and expanded entropy weighting method. In this research, the extended entropy weighing method and the Fuzzy-Moora approach were utilized to weigh the criteria and proj...

Geothermal energy is a renewable energy source which can provide base-load power supply both for electricity and direct uses, such as space heating. In this paper, district heating systems that are fed by geothermal energy, the so-called geothermal district heating systems, are studied. It is proposed to apply a hot water storage tank in these systems to store hot water in times of low-load and...

Understanding of the permeability of reservoir rocks at elevated temperature is becoming increasingly important both in oil field development and stimulation and in geothermal energy production. Rock properties such as permeability are often measured at ambient conditions with reservoir characteristics then based on these ambient measurements. liowever, rock and fluid properties may be radicall...

The dominant structural feature of Jordan is the north-south trending Dead Sea Rift. It is an active part of the African-Syrian Rift, which extends for about 6000 km, from east Africa through the Red Sea, Wadi Araba, Dead Sea, Jordan Valley to south Turkey. The groundwater aquifers of Jordan are divided into three main complexes: A deep sandstone aquifer complex, an Upper Cretaceous aquifer com...

office building, or school, or replace your heating and cooling system, you may want to consider a geothermal heat pump (GHP) system. GHP systems are also known as GeoExchange, ground-source, or water-source heat pumps (as opposed to air-source heat pumps). Regardless of what you call them, energy-efficient geothermal heat pumps are available today for both residential and commercial building a...

This paper introduces a theoretical analysis of a comple problem involving non Fourier and non Darcy behavior. A high quality experime,tal set up is used for a chosen configuration and results agree with a numerical explicit network model. The physical analysis based on relevant literature is especially well conducted and this pioneering paper will be of interest in the field of geothermal ener...

In NE Iceland there are ample geothermal resources both high temperature and low temperature geothermal fields as well as boiling low-temperature or medium enthalpy resources. It is of utmost importance not to waste the energy even where the resources are ample and cascade use of the energy is desirable. Many of the high-temperature fields in the area are now being harnessed for electricity pro...

The Queensland Government recently awarded A$15 million to the University of Queensland to establish a new “hot rocks” research and development centre, called the Queensland Geothermal Energy Centre of Excellence. The vision for the Centre is to provide urgent, forward looking research, development and support for establishment of geothermal energy as a clean energy option through a program of ...

Geothermal power generation and mineral extraction from geothermal brines are affected by chemical processes within the reservoir. Until recently, numerical simulation technology for geothermal systems could not handle most chemical processes, except for tracking total salinity, one or two noncondensable gases, and non-reactive tracers. The Lawrence Berkeley National Laboratory (LBNL) has devel...
