Configuration Research On Energy Storing Geothermal System

In geothermal development systems, water pumping and injecting costs much energy and money. In order to balance the energy consumption of injection and production, surplus energy is introduced to inject water into geothermal reservoir intermittently. So that the thermal fluid can be replenished, and pore pressure of geothermal reservoir can be improved. In this way, an energy storing geothermal development system could be figured out. In order to avoid building large tail-water storage facilities on ground, tail-water can be stored in shallow strata or in sea. Therefore, two system configurations are proposed. Such systems can be part of a hybrid renewable energy system, which outputs stable energy.
