Battery Energy Storage Technology is the pivotal technology that will usher in the era of renewables. It is through batteries that more renewables can be added to the energy mix and the problem of intermittancey associated with renewable energy can be fully alleviated.
Ever since Lithium Ion batteries arrived on the scene, they have given a new lease of life to electric cars. Many countries including Germany have shown ambition to go complete electric in terms of the year 2030.
In very large scale batteries, other than Lithium Ion, flow batteries and Sodium Sulphur are also popular.
At the MIT, liquid battery technology has shown good promise. Not only large scale batteries can provide energy during times of lull for renewables but also for conventional power they can provide respite. Batteries are characterised by both the instantaneous power that they can deliver ( in MW scale ) and the total energy storage capacity (in MWh).
Battery Size (MWh) Battery Power Capacity Type Location Manufacturer
5 10 MW Lithium Ion Kilroot Power Plant, UK AES Energy Storage
10 5 MW Vanadium Redox Liaoning, China Ronke Power
12 3 MW Lithium Ion Shenzhen, China CSG
20 40 MW Lithium Ion Sendai, Japan Toshiba
36 6 MW Lithium Ion Hebei Province, China SGCC, BYD
60 15 MW Vanadium Redox Hokkaido, Japan Sumitomo Electric Industries

In the near future, a 400 MWh battery with a 100 MW instantaneous power capacity is set to come online in California, USA.
More recently Tesla has won a contract to deliver the biggest battery in the world that will be based in Australia and will have Lithium Ion Chemistry. This battery will be produced by Tesla in just 100 days.
