“Battery energy storage systems, often referred to as BESS systems, are devices that make it possible to store energy from renewable sources or the power grid. Lithium-ion batteries — the same technology that powers mobile phones and electric cars — have long been the most common type of battery used to meet large-scale storage needs.”
“In addition to lithium-ion batteries, there are emerging technologies including flow batteries and iron- or sodium-based batteries. Still others are currently in the research and development pipeline of private or public laboratories.”
“Efficient energy storage is vital to the energy transition, making it possible to optimize the use of produced renewable energy by storing what isn’t needed immediately for later use (e.g., if the grid goes down or if there is a spike in demand). Stored energy bridges gaps in production and compensates for fluctuations to ensure an uninterrupted power supply.”
