News in brief from around the world of energy storage.

Flow batteries will take another major step towards widespread bankability with Lockheed Martin Energy launching its own system before the end of the year.

Adding energy storage gives solar developers and the industry in general the ability to “keep going”, while offering both lithium and flow battery systems covers a “wide-range of use cases”, NEXTracker CEO Dan Shugar has said.

Well, we seem to say it at the end of every year, but 2017 seemed a lot busier than 2016, 2016 was busier and more exciting than the year before that, and so on! There have been some hints already on what the industry and its observers expect to see in 2018 and we do not doubt energy storage will continue in its rise to become a flexible cornerstone of the world’s electricity infrastructure. In the meantime, let’s reflect on the top news stories of last year, as reported by Energy-Storage.News and based on readership statistics from you:

Since the launch of the site almost four years ago, Energy-Storage.News (and PV Tech Storage as it was previously known), has consistently brought you high-quality blogs from both guest contributors and our team of journalists and experts here at Solar Media. Here’s just a selection of some of the best guest blogs we ran from January to June, 2017:

The CEO of Primus Power agrees that at present, lithium battery systems are more bankable than the flow battery energy storage systems of the type his company makes, but asserted that he believes this will change over time.

The developer of one of the world’s biggest battery energy storage systems (BESS) installed globally so far will be taking its vanadium redox flow systems into the international market, beginning with a pilot in Belgium.

The government of the state of South Australia has named four utility-scale energy storage projects which it will support with grants toward the total cost of development.

Over the past couple of weeks, various flow battery makers have touted new sales and supply chain agreements as the fledgling sector fights for a share of the stationary energy storage market.
