The European electricity storage market has seen an impressive growth over the past two years. Whereas in 2015 some 300MWh of battery storage capacity was newly installed, just two years later in 2017, more than 700MWh was added. Delta-ee’s Valts Grintals gives you some highlights and pinpoints some recent trends across the continent.

The second part of our round-up of the best guest blogs of the year covers as wide a range of topics as yesterday’s list, from a mixture of experts and industry stakeholders.

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:

In a world where energy storage will play an increasingly important role – in balancing renewables, reinforcing the network, and reducing energy costs – how important will ‘brand’ be?

Britain could be the best “scale-up” market in the world when it comes to deploying energy storage batteries, leaning on years of experience in solar PV, the chief of one manufacturer has said.

While lithium-ion is rapidly racing ahead to become the “de facto grid storage solution” and is the most popular technology choice by far, vendors of other types of batteries are also targeting the market, with varying degrees of success.

In the past month we have heard a lot about the future of storage in the UK. From plans by the government and regulator to enable greater flexibility across electricity networks to changes to technical rules governing the market, there’s been a sense that a great deal is changing. Analyst Lauren Cook of Solar Media’s in-house market research team takes a look at the utility-scale pipeline figures behind the headlines.

Florian Mayr, partner at Apricum – The Cleantech Advisory, reflects on knowledge gained in energy storage’s rapidly growing markets and offers his five key ingredients for success.

The world pipeline for energy storage on the utility side of the meter has doubled in the past year, reaching 3.4GW, according to new research by I.H.S.

According to the latest GTM Research figures, energy storage is coming into its own and is no longer confined to a handful of US states. 21 states now have 20MW of storage projects proposed, in construction or deployed. Further, 10 states have pipelines of more than 100MW.
