The Elements Of Direct Uses
Journal Article: The Elements Of Direct Uses
AbstractDirect uses of geothermal energy are important in many countries of the world. Well-known examples are district heating (hitaveita) in Iceland, industrial processing in New Zealand, greenhouse heating in Hungary, and traditional bathing uses in Japan. Although direct uses are also called non-electrical applications, they span the whole range of geothermal temperatures, as evident from the Lindal Diagram shown in Fig. 1. A recent paper on direct uses is that of Gudmundsson and Lund (1985). Because of the many possible applications of geothermal energy, there is a need to identify the main elements that make up direct use projects. The purpose of this paper is to consider these elements, in an attempt to better organize the field of geothermal engineering. The paper concerns the technologies needed to bring geothermal fluids from resource to user. However, corrosion and water quality matters are not discussed, neither are environmental issues. Geothermal drilling, production and reservoir engineering are also outside the scope of this paper.
