The annual energy capacity of batteries used in utility-scale applications will be seen to increase by a factor of more than 100 between now and 2023, according to a new report published by US analysis firm Navigant Research.

Barclays has voiced the opinion that solar PV-generated energy coupled with storage presents a long term disruptive risk to electric utilities in the US, as it was reported the bank’s investment arm had downgraded the entire electric sector of the US high grade corporate bond market.

Electricity storage could be the “glue” that holds electricity networks together in the near future, according to UK politician Alan Whitehead MP, speaking at a parliamentary reception held to launch a new report published by the Electricity Storage Network.

In the year that has passed since Germany began offering subsidies for lithium-ion battery systems for residential use, around 4,000 solar-plus-batteries have been installed, the country’s Federal Solar Industry Association (BSW Solar) has announced.

Bosch claims it has developed an energy management system for optimising electrical and thermal energy consumption from solar power systems, which the company will launch at this year’s Intersolar exhibition and conference.

The International Electrochemical Commission (IEC) will begin a programme of standardisation for redox flow batteries – which can be used for large scale energy storage applications – following discussions which were initiated in Japan in October 2013.

SolarCity looks likely to resume its programme of deploying residential energy storage systems in California, following a preliminary ruling by the state’s Public Utilities Commission (CPUC) appeared to rule in the company’s favour.

Representatives of battery and energy storage companies including AES Corporation and FIAMM believe the priority for the nascent energy storage industry should be to standardise technologies, along with developing a regulatory framework that recognises the value of storage.

Energy storage technologies are not the “silver bullet” they have sometimes been hyped as, but nonetheless have a crucial role to play in a decarbonised electricity system, according to the International Energy Agency (IEA).
