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

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

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

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

The Internet of Energy is set to provide flexible, sustainable and affordable power for all. But we must not get complacent. Gianluca Mauro, Co-founder and CEO at AI Academy, argues that for this future to be realised, energy leaders need to develop a digital mindset.

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.

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.

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

The commercial and industrial segment is one of the most promising sub-sectors of the energy storage space. Julian Jansen of IHS Markit describes recent efforts to model the US C&I storage landscape and what it reveals about this dynamic emerging market. As told to Andy Colthorpe

Islands are particularly vulnerable to the impacts of natural disasters such as hurricanes. John Merritt looks at some of the emerging solutions to building more resilient energy systems through the deployment of microgrids that combine multiple energy generation and storage technologies
