In that case, the system could intra-day load for up to 3 times its nominal capacity (e.g., providing 24 MW for 8 hours). Eavor's system circulates a benign working fluid that's completely isolated from the environment in a closed loop, much like a massive subsurface radiator. These technologies are also dispatchable, which means they can be used when wind and solar resources—also known as variable renewable energy sources (VREs)—are not available. Slow (hours) These technologies are dispatchable, which means they are useful complements to wind and solar resources which have limited ability to be dispatched and are sometimes not available when needed. Geothermal power is constant (base-load), has high operability, is sustainable due to re-injection of cool fluids and is environmentally sound. Thomas A. Buscheck et al. Purpose of the research.
