An ‘electricity trading’ scheme to be launched by Reposit Power in Australia for residential energy storage system owners has been described by an analyst as “one of the most interesting examples” of software as a differentiator in the energy storage marketplace.

EOS Energy Storage has placed an order totalling more than 1MW from NASDAQ-listed power converter specialist Ideal Power, while both companies have launched new products since the start of the year.

Another large-scale project to test the grid-stabilising capabilities of battery-based energy storage systems will be launched at a solar farm in England, led by the National Grid, which is responsible for the UK’s electrical transmission network infrastructure.

Parallels are frequently drawn between the nascent energy storage business and solar 10 years ago – that it needs strong policy direction to take off. Andy Colthorpe profiles some of the areas emerging as world pioneers in supporting the deployment of storage.

Energy storage might not be cost effective in Germany as a method of helping the transition to a higher grid penetration of renewable energy, until that penetration level reaches as high as 90%, according to a leading think tank.
