With Japanese companies keen to learn from their counterparts in deregulated energy markets such as the UK, the Japan Energy Challenge provided the ideal forum for exchanging ideas. Andy Colthorpe reports.

Ensuring battery systems used in conjunction with solar perform safely and optimally is essential in ensuring the continued roll-out of storage technology. Robert Puto and Gerhard Klein of TÜV SÜD examine independent technical assessments that must be undertaken before a storage system is built.

Last year saw large-scale storage come of age in the USA and Canada, with some heavyweight storage portfolios starting to take shape. Speaking to four leading North American developers, Andy Colthorpe takes the pulse of a market poised for growth.

Paul Verrill, director of energy data analyst EnAppSys, explains how renewable energy generation and the integration of smart grid technologies and efficient energy storage systems can create a sustainable power system for the future.

Despite making huge strides forward, the energy storage industry’s work in helping stakeholders across the value chain understand the technologies and the roles they can play in a renewable energy future is far from done. Andy Colthorpe speaks with Energy Storage Association chief executive, Kelly Speakes-Backman, at the forefront of the industry’s push into unchartered regulatory, policy and public affairs matters.

While lithium-ion batteries get most of the headlines, long-duration energy storage solutions are gaining ground. Alice Grundy and Andy Colthorpe profile some of established and emerging concepts in this this increasingly important class of storage technologies.

As energy storage becomes an increasingly integral part of a renewables-based electricity system, new technologies are coming to the fore. Jens Noack, Nataliya Roznyatovskaya, Chris Menictas and Maria Skyllas-Kazacos from CENELEST, a joint research venture between the Fraunhofer Institute for Chemical Technology and the University of New South Wales, chart the rise of redox flow batteries, a promising alternative to lithium-ion-based systems.

Batteries are increasingly widely used in grid balancing, but there are many more applications where a battery can play an important role. With electric grids requiring periodic maintenance, batteries can stand in for the grid during downtime in order to reduce the impact on industry and households, writes Dieter Castelein.

Power markets are evolving and beginning to value flexibility ahead of generation. As the UK’s networks companies move to embrace flexible generation assets, Liam Stoker spoke to some of the country’s leading providers to identify the hurdles and solutions to a more flexible power grid.

At 4:52pm on Friday 9 August 2019, the UK suffered its first wide-scale blackout in over a decade. More than 1.1 million consumers were plunged into the dark as rail lines screeched to a halt, traffic lights failed and even airports reported problems. Liam Stoker looks at the root causes, and how battery storage came to the rescue
