Geothermal energy in Santiago del Estero, Argentina: a flesibility study of power generation from medium enthalpy thermal sources

"The Organic Rankine Cycle technology is a reliable way to convert heat into electricity, especially when free heat is available in form of renewable energy (biomass, geothermal, solar) or as exhaust heat from industries. In the present study the attention has been paid on the application of an...

In the present study the attention has been paid on the application of an ORC unit for the production of electric energy in Termas de Río Hondo, north-west Argentina, making use of an existing medium-temperature geothermal source. Earlier explorations of this area have assured a hot source of about 80-90°C at 900 m of depth, thanks to a fractured saturated sedimentary basin of more than 6000 m of depth. Commercial and economic evaluations have been carried out to analyse the ORC units that are available in the market that can work with such low temperature. Three companies have been selected as potential providers of a unit to be installed in Termas de Río Hondo. The potential energy production from these units is calculated and various economic scenarios are evaluated to function as a reference to potential strategic decisions. The units’ gross power output ranges from 30 to 300 kWe, with a required hot water flow rate between 10 and 57 l/s, and a cold water flow rate between 15 and 155 l/s. The economic analysis is based on the calculation of their payback period, sale price of produced energy and Internal Rate of Return. In general, it is found that larger units are more profitable, in the face of their higher initial cost." "La tecnología de los Ciclos Orgánicos Rankine es una manera confiable de convertir el calor en electricidad, especialmente cuando hay calor disponible en forma de energía renovable (biomasa, geotérmica, solar) o en forma de escape de aplicaciones industriales. En el presente estudio, se ha prestado atención a la aplicación de una unidad ORC para la producción de energía eléctrica en Termas de Río Hondo, noroeste de Argentina, utilizando una fuente geotérmica existente de temperatura media. Las exploraciones anteriores de esta área han asegurado una fuente caliente de aproximadamente 80-90°C a 900 m de profundidad, gracias a una cuenca sedimentaria saturada y fracturada de más de 6000 m de profundidad. Se han llevado a cabo evaluaciones comerciales y económicas para analizar las unidades de ORC que están disponibles en el mercado y que pueden funcionar con temperaturas tan bajas. Tres empresas han sido seleccionadas como posibles proveedores de una unidad para instalar en Termas de Río Hondo. Se ha calculado la producción potencial de energía de estas unidades y se ha evaluado diversos escenarios económicos para que funcionen como una referencia para eventuales decisiones estratégicas. La potencia bruta de las unidades varía entre 30 y 300 kWe, con un caudal de agua caliente requerido entre 10 y 57 l/s, y un caudal de agua fría entre 15 y 155 l/s. El análisis económico se basa en el cálculo de su período de amortización, en el precio de venta de la energía producida y en la Tasa Interna de Retorno. En general, se encuentra que las unidades más grandes son más rentables, a pesar de su mayor costo inicial."
