The Energy Storage Report 2024

Now available to download, covering deployments, technology, policy and finance in the energy storage market

Smart islands, flow batteries and Internet of Energy: your free copy of PV Tech Power


Volume 15 of PV Tech Power, from our publisher Solar Media, has just hit the virtual shelves – and the quarterly technical journal is free to download from the PV Tech site.

As you may know, for three editions now, has contributed, compiled and curated ‘Storage & Smart Power’, a dedicated section which brings you topics high in relevance and rich in insights.

So in addition to the main journal itself, which leads off on an in-depth look at the future of global solar asset management and also has features on post-subsidy solar in Europe, more on the environmental strengths of floating PV, diagnosing PID (potential-induced degradation), how oil and gas majors are investing in solar and much more, you can read three articles from our team at ESN and a guest contributor.

What’s in ‘Storage & Smart Power’ this quarter

As the quarterly journal has grown in popularity, both as an online presence and in printed form at trade shows and exhibitions, we decided that energy storage and the increasingly connected nature of PV systems and energy storage deserved its own section, in much the same way batteries gradually became a larger part of PV Tech before was launched in 2015.

Smart Islands: ‘Taking smart to the edge of the world’

A couple of years ago, it was pointed out that even while lithium battery prices remained high (or at least, much higher than they are now), they still worked out cheaper in remote grid or island settings in competition with the imported diesel fuel which is used for the most part in such energy networks.

As such, various ‘smart island’ projects have blossomed already this century. Solar Media writer David Pratt spoke with integrators and experts about projects including the Portuguese island of Graciosa, the Isles of Scilly and more. David looked at the technical and financial challenges of these ‘living laboratories’ for the future of distributed energy.

Flow energy storage: ‘Long time coming’

You may have seen my blog a couple of months ago on, which looked at some anecdotal evidence and recent news announcements around redox flow energy storage. Many have tried and some have already failed to commercialise the technology, which was originally a NASA project decades ago.

Yet flow batteries, or flow machines, which offer degradation-free long duration energy storage over many years of expected system lifetimes, have been picked out by the likes of Navigant Research as one of the clean or distributed energy technologies most likely to succeed in the not-so-distant future.

This time around I took a slightly more analytical approach and spoke with four manufacturer-evangelists for flow energy storage, all of whom are taking a different approach to the commercialisation question. Primus Power, VRB Energy / Pu Neng, RedT and ESS Inc all put forward their case and the article concludes next quarter in PV Tech Power Vol.16.

Internet of Energy: ‘Like using a hammer to put on your shoes’

InnoEnergy is a collaborative Europe-wide programme to support and promote sustainable energy. As part of that, AI Academy is running an ‘Internet of energy bootcamp’ for senior professionals and executives, bringing decision-makers up to speed on the systems, software and concepts that might well come to dominate their futures in the energy industry.

“It is no good writing an amazing machine learning algorithm or building a state-of-the-art neural network if it is not then applied to solving the business’s problems.

“If placed at the centre of the business, with a vision for its application to the firm’s challenges, AI can analyse all of the data that the company has about customers’ energy needs and the power available on the network,” AI Academy’s Gianluca Mauro writes.

Summer shows

This edition of PV Tech Power, as mentioned, can be downloaded from the link on the PV Tech website. It will also be available in print in limited quantities at international shows this summer, including Intersolar Europe / ESS Europe in Germany later this month.
