Misconceptions over the true value of energy storage are developing because of a “narrow focus” on the initial costs of the technology, a report has concluded.

The US Department of Energy is to fund six projects trialling the combination of solar and energy storage.

Flow battery manufacturer ViZn Energy Systems has won a contract to provide a 128kW/320kWh system for a US department of energy project.

News in brief: Nissan commits to longer range EV batteries from UK plant, a first in energy storage financing for Green Charge, American Vanadium plans acquisition of Gildemeister, Ceres and Honda developing solid oxide fuel cell stacks for power equipment.

Analysis firm IHS has said that as of the end of 2015’s fourth quarter, the pipeline of planned energy storage projects using batteries or flywheels had reached 1.6GW, in a year which had seen a “change in stakeholder mentality” in favour of the technologies.

News in brief: SolarEdge’s Powerwall-compatible StorEdge self-consumption solution is now available internationally; AES completes another 10MW project in Holland which will provide grid services; and Japan’s Sumitomo Corporation’s Willey Battery Utility is the latest energy storage system to join PJM’s frequency regulation market.

Placing a battery onto the grid is an economic investment. Matthew Hunt from the UK’s Chargesync discusses strategies for extracting the maximum value from devices and systems through optimising performance.

California’s CalCharge is a partnership between public and private sector, aiming to accelerate the adoption of energy storage in the state. Andy Colthorpe of Energy Storage News spoke with CalCharge president Danny Kennedy, the Australia-born former chief of US residential PV installer Sungevity who has a colourful background in eco-activism and the programme’s recently appointed manager, Alex Luce.

Corporations and utilities are already interested in energy storage but must collaborate to advance deployment and lower costs, avoiding some of the past mistakes of the PV industry, according to the heads of one California-based industry group.

The unsung hero in the grid revolution is the data that enables new technology and provide more control of an increasingly complex system. Andy Colthorpe explored the growing role of Big Data in energy networks in a feature article for the downstream solar technology journal PV Tech Power.
