Distributed Storage

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.

The Australian Energy Regulator has released its Default Market Offer for 2021-2022, and it is another fall in electricity prices, especially if you live in South Australia, New South Wales or south-east Queensland. The regulator says one of the main factors driving the now continuous fall in electricity prices is the investment in renewables, in particular the estimated uptake of rooftop solar.

New South Wales network operator Ausgrid yesterday launched its first community battery in Beacon Hill, north of Sydney. It is one of three community batteries being installed across Sydney allowing solar customers to store their extra energy at no additional cost.

With 7,600 residents and many more travellers recharging at its holiday properties each year, Ingenia Communities Group is set to lead the retirement and affordable-travel-accommodation sectors towards solar uptake following a major investment by the Clean Energy Finance Corporation.
