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

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.

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.

UK solar developers WElink Energy and British Solar Renewables (BSR) have signed a £1.1 billion (US$1.6 billion) deal with China National Building Materials Group (CNBM) to develop solar energy projects and zero-carbon homes in the UK.

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.

DNV GL’s new recommended practice guidelines for grid-connected energy storage systems is aimed at “reducing risks” for investors and the wider community, the document’s lead author has said.

Panasonic has given the first indication of the expected size of its investment in collaborator-competitor Tesla’s battery Gigafactory, which according to the company’s president could be up to US$1.6 billion.

Globally, energy storage is developing rapidly. Businesses that are shaping the market are being asked to nominate themselves to join the Energy Storage 100, a new industry initiative from Energy Storage News’ publisher, Solar Media.
