There are seven utility-scale energy storage system integrator companies that currently lead a global market poised for significant expansion, with Fluence and Tesla currently competing for the top spot, according to a new industry ranking report from Guidehouse Insights.

The US national Energy Storage Association (ESA) has adopted a goal for the deployment of 100GW of new energy storage using a range of technologies by 2030, updating a previously set 35GW by 2025 target.

Flow batteries have so far, failed to live up to the disruptive potential they promise, a new report says, but authors Alex Eller and William Tokash at Navigant Research have identified 12 leading vendors in the nascent field, based on metrics of strategy and execution.

While recycling of lithium and other materials such as cobalt from batteries will greatly increase in the coming years, the potential availability of second life batteries should not be underestimated, according to new research and data.

This year has already seen “significant acceleration” of activity in the global grid-connected energy storage market, with 4.3GW expected to be deployed this year, analysis firm IHS Markit has said.

Commercial and industrial (C&I) energy storage in Europe, described by one analyst as “beginning to take off”, is the “most exciting” segment of the market at the moment, according to BYD’s global service partner.

VC funding for energy storage projects increased significantly, while debt and public market financing remained “steady” during 2017, Mercom Capital has found.

Four projects have been awarded £42 million (US$59.6 million) of UK government money between them to conduct research aimed at overcoming battery challenges, mainly focused on electric vehicles.

To date, Primary Control Reserve (PCR) has dominated the energy storage debate in Germany with more than 100MW of battery storage installed in 2016 alone specifically for participating in the PCR market. At the same time, with close to 25,000 systems sold in 2016, residential storage has been stealing the limelight in the behind-the-meter segment. Julian Jansen of Delta-ee looks at how his team expects the commercial and industrial (C&I) segment to start catching up.

There have been modest year-on-year increases in the number of PV installers in Germany and the UK offering energy storage to their customers, according to a survey by EUPD Research.
