ILiA Special Report - ESS 2040

This new special report discusses why the battery energy storage system market is set to surge through 2040. 

The fundamental requirement of any electrical grid is balance: generation must match consumption at every moment. Energy storage systems (ESS) help to decouple the tight dependency between generation and demand, particularly as the world shifts to renewable power generation, giving grid operators a buffer that makes the whole system more flexible, resilient, and cost-effective. 

This fundamental need, alongside the falling cost of batteries, is accelerating the adoption of ESS. 

“Lithium is not only the essential enabler of technologies driving a greener and more sustainable society – today and for generations to come but also for energy security.” – Anand Sheth, Founding Chairman, ILiA
