Research shows Italy leading in grid storage

New research shows grid energy storage in Italy is the biggest market in Europe. Sodium battery technology dominates, thanks to the Terna SANC project which uses NAS battery systems from NGK Insulators.

Germany might get most of the attention but when it comes to European grid-scale battery storage the real action is in Italy, a new report says. Based on an analysis of US Department of Energy data for Energy Storage Update Europe 2015, Top markets for energy storage in Europe shows Italy dominating in grid-scale storage by a large margin.

Thanks mainly to a gigantic battery installation by Terna, the transmission system operator (TSO), Italy has almost double the amount of battery capacity in train as the next 11 largest European energy storage markets put together.

Terna’s SANC complex in Campania, totalling more than 278MWh of storage, not only surpasses the battery storage capacity of any other European market but also skews the electrochemical technology mix for the whole continent.

It means Europe’s dominant electrochemical technology for grid-scale applications is set to be sodium-based batteries, rather than lithium-ion, for some time.

In a week where continued fears over radiation leakage call the future of the country’s nuclear fleet into question, there is at least one piece of good energy news coming out of Japan. NGK Insulators and Sumitomo Electric Industries have both been chosen by the Japanese Ministry of Economy, Trade and Industry to find ways of driving down the costs of energy storage.

Sweet solution boosts sodium battery storage

27 September 2012
Sodium batteries could improve their capacity by 20%, thanks to researchers at the Tokyo University of science, reports DigInfo TV. They have produced a new type of carbon anode by heating sucrose up to 1,500ºC, which has increased the capacity of sodium ion batteries to 300mAh, say the scientists.The researchers are hoping this development is another step in the quest to replace lithium as the dominant – and expensive – battery chemistry.
