Methodology for the quantitative exploration for sites for salinity-gradient solar ponds
- Univ. of Texas, El Paso, TX (United States)
Salinity-gradient solar pond (SGSP) energy production is one of the proven solar energy technologies, however only in several instances have these ponds yet proven to be economically competitive. Electricity generation, water desalination, medium grade industrial heat production, and hydrometallurgy have been successfully demonstrated, however, on the whole the technology is seeking a niche within which to thrive and develop. The present study provides a rational basis for the selection of new SGSP sites, and a methodology has been developed to consider the multitudinous variables necessary in such a decision. Twenty physical criteria are considered in SGSP site selection. Four value and seven cost criteria have been considered in the present study. Large values of F correlate with the more favorable SGSP sites. This methodology has been applied to over 100 sites in west Texas and eastern New Mexico. Sites tested include playa lakes, salt lakes, artificial lakes, and empty ground, located both near and distal from active industrial sites in the region. Distance to potential energy user is of great importance. Hydrometallurgical processes may benefit from a SGSP during sodium sulfate production. Salt is also such an important driver in the favorability index that certain industries result with high values. Notable are the nuclear waste storage facility at the WIPP site and the potash mining industry in the Potash Enclave, where salt is a waste product of their activities.
