Energy storage has always been part of electricity systems, but why has battery storage gained so much attention during the past few years? And what is the difference?

With the energy transition being at the heart of climate change policies, policymakers, investors, energy, and technology companies have been trying to imagine what the future electricity system will look like.

In this new electricity system, solar and wind power will be 100 percent reliable, consumers will be able to be energy independent relying exclusively on their rooftop solar and communities will be granted access to clean electricity without expensive transmission infrastructure.

In addition, the energy transition movement will not only need to address the issue of intermittent renewable energy electricity generation, but also the one of integrating renewable energy into the grid.

In other words, battery storage constitutes a technology with multiple applications and endless possibilities. Its role in the energy transition is expected to be pivotal.

A sneak peek at the facts:

- Lithium-ion batteries constituted 90% of utility-scale stationary energy storage capacity worldwide in 2016.
- According to IEA, for the Paris goals to be met, the world will need 21GW of battery storage by 2021.
- Lithium-ion batteries used to cost $1,085- 4,100 /kWh in 2010, and in 2016 they cost under $140/kWh.
