Power to the people

By Liam Stoker, Solar Media

The UK’s energy retail market is witnessing an exodus of customers leaving the so-called Big Six for independent suppliers, who are attracting them with home solar systems and a battery to match. Liam Stoker uncovers what’s behind the trend for new energy suppliers taking to domestic PV.

Corporate takeover: the end of independence?

By Andy Colthorpe, Solar Media

The growth potential of energy storage has drawn interest from some of the biggest names in the power business and beyond. With the trend set to continue, Andy Colthorpe explores how three of the recent targets are faring under new ownership.

Easing the risks of battery investment

By Dr. Davion Hill, DNV GL

As the building blocks of energy storage systems, batteries have a key role in influencing system design and economics. Davion Hill of DNV GL explores the importance of testing the performance of individual battery cells in minimising the exposure of battery buyers to technical risks.

Cryogenic, long-duration energy storage in a 100% clean energy future

By Dr. Javier Cavada

A key missing piece in the clean energy puzzle is the question of how to provide baseload power in an electricity system dominated by intermittent renewables. Javier Cavada of Highview Power examines cryogenic long-duration storage as a possible solution.

Peak time to take action

By Andy Colthorpe

In the hierarchy of grid needs, peaking power is often a priority in terms of providing resiliency and balance to the network. This is usually provided by natural gas turbines, which come at a high environmental and economic cost. Andy Colthorpe charts the rise of the solar-plusstorage peaker plant.

Is California dreaming? Energy storage’s role in reaching 100% renewables

By Andy Colthorpe

This year’s Solar Power International trade show dedicated what seemed like almost as much space to energy storage as solar. As Andy Colthorpe reports, this is likely a strong indication of the way the world is adopting renewable energy, particularly California, where storage looks set to play a key role in helping the Golden State realise its green ambitions

Accelerating to 100%

By Andy Colthorpe

Andy Colthorpe speaks to Janice Lin of the California Energy Storage Alliance on what sort of role energy storage will play in reaching the ‘100% carbon-free retail electricity’ goal of the state’s SB100 legislation

The smarts inside the storage

By Enrico Ladendorf; Bryce Evans

Energy storage projects often fail to deliver value because of economic miscalculations. These computational issues, however, can now be mitigated by applying software, analytics and machine learning, write Enrico Ladendorf and Bryce Evans

Is that battery cycle worth it? Maximising energy storage lifecycle value with advanced controls

By Dr. Andres Cortes; Ben Kaun

Smoothing and firming are often discussed to make renewables appear more like conventional generation to the grid operator, but how smooth and how firm does that generation need to be? How can the attributes and operations of energy storage be appropriately measured relative to cost? Andres Cortes and Ben Kaun of the Electric Power Research Institute discuss recent work addressing these issues

Virtual reality: VPPs in a break with tradition

By Andy Colthorpe; David Pratt

Cloud-aggregated virtual power plants using residential or C&I battery storage as part of a smart energy management system can benefit the grid, integrate renewables and EVs and hopefully add a powerful long-term value proposition for home storage. Andy Colthorpe and David Pratt report on how some of the UK’s first VPP projects are proving the concept

Long time coming: Part 2

By Andy Colthorpe, Solar Media

First developed by NASA, flow batteries are a potential answer to storing solar – and wind – for eight to 10 hours, far beyond what is commonly achieved today with lithium-ion. In the second of a two-part special report, Andy Colthorpe dives deeper into questions of bankability, market segmentation and manufacturing strategies

Long time coming

By Andy Colthorpe

First developed by NASA, flow batteries are a potential answer to storing solar – and wind – for eight to 10 hours, far beyond what is commonly achieved today with lithium-ion. In the first of a two-part special report, Andy Colthorpe learns what the flow battery industry faces in the fight for commercialisation.

Taking smart to the edges of the world

By David Pratt, Solar Media

Islands around the world provide ideal conditions for trialling new approaches to energy provision. David Pratt reports on some of the work going on globally to bring the benefits of cutting-edge renewable energy, storage and smart grid technologies to the world’s geographically isolated communities.

What a difference a year makes

By Andy Colthorpe

2017 was tet another record-breaking year for energy storage. Riding high on expectation, the industry is braced for challenges and successes in equal measure this year too. We canvassed opinions from some of the world’s leading trade associations and representative bodies on the year just gone and what 2018 could bring
