Battery storage is one method to store power. However, geologic (underground) energy storage may be able to retain vastly greater quantities of energy over much longer durations compared to typical battery storage.

The U.S. Geological Survey (USGS) has the capability to research and assess possible domestic geologic energy storage resources to help prepare the United States for the future of renewable energy.

地质能源储存

欲了解更多信息，请联系:美国地质、能源与矿产科学中心。随着美国从化石燃料转型，其经济将更多地依赖可再生能源。由于目前的可再生能源有时会产生可变的电力供应，因此储存能量以备电力供应低于电力需求时使用是很重要的。电池储存是一种储存电力的方法。然而，与典型的电池储能相比，地质(地下)储能可能能够在更长的时间内保留更大量的能量。地质储能也具有较高的灵活性;许多不同类型的材料可用于在各种地下环境中储存化学能、热能或机械能。美国地质调查局(USGS)有能力研究和评估可能的国内地质能源储存资源，以帮助美国为可再生能源的未来做好准备。
