In the US, there is a growing trend for battery storage systems to be directly paired with onsite wind and solar generation, creating hybrid resources. Will Gorman from Lawrence Berkeley National Laboratory looks at when and where this configuration makes sense — and why sometimes it doesn’t.

Andy Colthorpe speaks to Maria Skyllas-Kazacos, one of the original inventors of the vanadium redox flow battery, about the origins of the technology and its progression.

Commissioned at the start of this year, the Alamitos Battery Energy Storage System in California is a landmark project for the industry in having competed against natural gas to provide peaking capacity for the grid. Andy Colthorpe finds out the project’s backstory from Fluence’s Ray Hohenstein and AES’ Mark Miller.

What do Ireland, Germany, Poland and Spain all have in common? Well, like the other members of the European Union they all have a requirement to decarbonise and a desire for sustainable economic growth. Andy Colthorpe speaks with energy storage associations from those four countries to hear about their unique situations as well as the opportunities and challenges they share.

Battery storage is flexible, remarkable — and investable — but you need to know what you’re doing and know where the market opportunities and limits lie. Renewable and clean energy financier Laurent Segalen from Megawatt-X explains some of the things he’s seen as batteries have become an infrastructure asset in their own right.

Battery storage deployments, both with and without solar, have been in a new growth phase that has smashed quarterly records consistently while costs have continued to fall. Nonetheless, the maturity of the industry is not always reflected in the information available to financial decision-makers, writes Adam Walters from Stoel Rives LLP.

Software is rapidly becoming recognised as key to the value proposition and bankability of energy storage, which in turn lies at the heart of the low carbon energy transition. Andy Colthorpe speaks to three providers of software aimed at the energy storage industry.

With a project pipeline in excess of 14GW, a developing regulatory envelope and maturing revenue streams, the UK’s energy storage sector continues to be at the forefront globally. Molly Lempriere charts the market’s development to date and uncovers how it has responded to deployment barriers.

Using abundant resources for components and as ‘fuel’, zinc batteries can be a cost-effective, flexible and scalable technology to deliver many of the needs of a resilient, low-carbon energy system, says Ron MacDonald at Zinc8.

Growth in renewables and corresponding market pricing is the key driver for the commercialisation and global adoption for vanadium flow batteries (VFBs) and an important reason why we will see further growth for this technology over the years to come, says Ed Porter of Invinity Energy Systems.
