Dear Colleagues,

Geothermal resources are used in the generation of electricity and for numerous direct thermal applications including space heating and cooling, industrial processing and agricultural applications. Increasingly, combined heat and power projects involving both power generation and direct thermal applications are helping to maximize not only resource utilization, but also economic return as well. Low temperature geothermal resources, coupled with heat pumps, provide both space heating and cooling.
Recent trends in the geothermal industry include greater emphasis on low temperature power generation, combined heat and power, the development of enhanced geothermal systems, the conversion of abandoned oil and gas wells to geothermal producers and the extraction of minerals from geothermal brine, thus allowing for greater thermal recovery while at the same time providing an important additional source of revenue.
As the demand for electricity and thermal energy steadily increases and fossil fuel prices spiral continually upwards, greater and greater emphasis is being directed toward the development of environmentally responsible and increasingly cost competitive renewable energy resources such as geothermal. This special issue covers current development trends as well as research and development directed toward enhanced geothermal system development and the extraction of minerals from geothermal brines.

Abstract: The aim of the paper was to provide a critical and comprehensive review of desalination using geothermal resources. The main advantage of geothermal energy is that thermal storage is unnecessary, since it is both continuous and predictable. A high-pressure geothermal source, for example, allows the direct use of shaft power on mechanically driven desalination, while high temperature geothermal fluids can be used to power electricity-driven reverse osmosis plants. The availability and/or suitability of low and high temperature geothermal energy, in comparison to other renewable energy resources for desalination will be discussed.
