Grid energy storage, also known as large-scale energy storage, are technologies connected to the electrical power grid that store energy for later use. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources like nuclear power, releasing it when needed.
In order to cope with both high and low load situations, as well as the increasing amount of renewable energy being fed into the grid, the storage of electricity is of great importance. However, the large-scale storage of electricity in the grid is still a major challenge and subject to research and development.
When asked to define grid-scale energy storage, it's important to start by explaining what “grid-scale” means. Grid-scale generally indicates the size and capacity of energy storage and generation facilities, as well as how the battery is used.
Grid-scale batteries have a round-trip efficiency (RTE) measurement, which shows the energy lost during storage and retrieval, usually 70–90%. Lithium-ion batteries reach an industry-high RTE of 90%+, lead-acid measures about 70%, flow batteries are around 50–75%, and metal-air designs can be as low as 40%.
Any electrical power grid must match electricity production to consumption, both of which vary significantly over time. Energy derived from solar and wind sources varies with the weather on time scales ranging from less than a second to weeks or longer.
The current market for grid-scale battery storage in the United States and globally is dominated by lithium-ion chemistries (Figure 1).
