Invitación para el workshop - webinar acerca del almacenamiento de energía solar termal en un reservorio geotérmico sintético, que se realizará el 19 de Mayo 2020.
NSF y la Universidad de Utah están invitando a un taller virtual sobre “Almacenamiento de calor solar estacional subsuperficial a gran escala para obtener un valor futuro”, como parte del concepto de almacenamiento de energía de batería geotérmica.
- Fecha y hora: 19 de mayo de 2020 – 10:00 a.m. a 2:30 p.m. MDT a través de Zoom
- Se requiere preinscripción: envíe un correo electrónico a [email protected] y se enviará una invitación
El concepto de almacenamiento de energía de batería geotérmica (“GB”) se ha propuesto como un método de almacenamiento de energía renovable a gran escala. Esto es particularmente importante ya que la electricidad solar y eólica se están introduciendo en las redes eléctricas. Y, el almacenamiento económico a escala de servicios públicos aún no está disponible para manejar la naturaleza variable de la energía solar y eólica.
El concepto utiliza la radiación solar para calentar el agua en la superficie y luego inyectar esta agua caliente profundamente en la tierra. Esta agua caliente crea un depósito geotérmico de alta temperatura aceptable para la producción de electricidad geotérmica convencional o para aplicaciones de calor directo. Almacenar agua caliente bajo tierra no es una idea nueva, pero la característica única del GB es considerar regiones en cuencas sedimentarias con formaciones saturadas de agua de alta porosidad y permeabilidad. Para ciertos reservorios, los cálculos sugieren que casi el 100% del calor almacenado se puede recuperar prácticamente, y que a largo plazo incluso el almacenamiento estacional es posible.
Los autores han presentado varias publicaciones sobre GB considerando las variaciones de los parámetros del yacimiento. Esta es una revisión de los cálculos realizados y las conclusiones para un sistema GB inferido de los cálculos. Se observa la disposición potencial del sistema GB de pozos y las posibilidades de inyección y producción y la recuperación final del calor por valor económico.
