Introduction
Details technologies that can be used to store electricity so it can be used at times when demand exceeds generation, which helps utilities operate more effectively, reduce brownouts, and allow for more renewable energy resources to be built and used. Underground Gravity Energy Storage system: A schematic of different system sections. In a future low-carbon electric grid dominated by intermittent wind and solar, we’re going to need technologies to store energy when it’s abundant and feed it back into the grid when it’s not. Similar to common rechargeable batteries, very large batteries can store electricity until it is needed. These systems can use lithium ion, lead acid, lithium iron or other battery technologies. But as countries switch from fossil fuels to clean energy, they need a new kind of backup system that can deliver power whenever someone flips a light switch, not just when the sun.
