Geothermal energy may be used in a number of ways in the industrial field. Potential applications could include drying, process heating, evaporation, distillation, washing, desalination, and chemical extraction. The most important energy considerations for an industrial complex are the cost, quality, and reliability. Geothermal energy may be attractive to an industry providing: (a) the cost of energy/lb of product is lower than that presently used, (b) the quality of geothermal energy is as good or better than the present supply, and (c) the reliability of geothermal energy is available for the life of the plant. Reliability and availability can only be proven by long-term use or testing
