Distributed Storage

Australian company Redflow has made its single largest sale, supplying 192 zinc-bromine flow batteries to waste conversion specialists Anaergia for US$1.2 million.

Australian mining technology company TNG Limited has had its flagship Mount Peake Project, which includes production plans for vanadium redox flow batteries and green hydrogen, recognised as nationally signifiant.

LG Energy Solution is facing consumer concerns with the Australian Competition and Consumer Commission (ACCC) confirming a recall notice for some of the company’s battery energy storage systems (ESS) due to potential defects which can cause overheating and fire.

With reins tightly held by China, a handful of players are trying to prise the production of a core ingredient of lithium-ion batteries out of Goliath’s hand before the battery boom begins in earnest with the electrification of the transport sector. The head of one of those companies, WA start-up International Graphite, spoke to pv magazine Australia about the hunger of both investors and customers, and the surprisingly collaborative race to feed global demand.

Australia’s infrastructure advisory body has added a number of renewable energy-related projects to its priority list, recognising the need for investment in the “once-in-a-lifetime transition from thermal generation to intermittent renewables.”

Porous nanostructured microspheres made of copper, iron, and iron oxide were used by an international research team as negative anode material in lithium-ion batteries. The new technique is claimed to provide three times more capacity than batteries based on graphite anodes.

The delicate balancing act between incentivising rooftop solar uptake, versus moderating its effects on the grid and electricity markets continues, with the Victorian energy regulator reducing the state’s minimum solar feed-in tariff from 1 July.

Smart metering services provider Intellihub cracked the million meter mark this week as the smart meter market in Australia and New Zealand surges off the back of continuing solar uptake.

The module manufacturer’s new storage unit, Trina Storage, aims to create innovative solutions for the combination of photovoltaics and storage, grid services and other applications.

Dutch scientist Bonna Newmann spoke with pv magazine about the present and future of vehicle-integrated PV from a technological and economic perspective. Solar panels installed on cars could have a payback time of only three or four years and ensure 10,000 km of pure PV-generated road travel per year, she said. Furthermore, if you live in a sunny place, you can drive an electric car with solar panels for weeks during summertime, without the need for recharging, she pointed out.
