These projects support the objectives of the DOE Grid Modernization Initiative by exploring ways to utilize geothermal energy in order to create the modern grid of the future.
The GMI works across DOE with the goal of developing the tools and technologies that measure, analyze, predict, protect, and control the grid of the future. As part of the GMI, the Beyond Batteries Initiative considers energy storage holistically. It focuses on opportunities for flexible generation, controllable loads, and new approaches to the broader concept of energy storage to effectively mimic many of the benefits of large scale batteries and to increase the reliability and resilience of the U.S. energy systems.
