Distributed Storage

Academics reviewed the historic price development of lithium-ion batteries and found the accepted model does not accurately reflect the full cost decline and technological improvement which has taken place. With more data points to compare, the team found batteries had improved even more than previously assumed.

As distributed PV grows, new grid codes have scared installers across some markets. Network operators want to gain control over grid export, even of smaller arrays. Additions of new array controllers and special gateways could be costly putting speedy development of PV at risk. Fret not, says Fimer, as the Italy-based power-electronics manufacturer has placed the solution to the problem already inside its latest inverter range.

The recharging station was designed by French automation group Sirea. It is powered by a solar carport and a small electrolyser.

The Australian Energy Market Commission, Australia’s energy rule maker, today released its draft determination on how to integrate energy technologies like solar and batteries into the electricity grid. In the draft, the Commission revived its proposal for a solar tax, immediately stirring backlash.

Queensland’s government will install five community batteries at regional substations across the state in a bid to time-shift its abundant solar resources.

Battery capacity in the distributed and large-scale sectors continues to grow, according the annual reckoning of the SunWiz oracle. Although still a complex proposition, for homeowners, battery potential is beginning to be utilised in the hundreds of megawatts by governments and utilities, with some interesting side hustles in the mid-sized energy-storage category.

A West Australian vanadium explorer, Technology Metals, has signed an agreement with a prominent Japanese company to explore the possibility of manufacturing vanadium electrolyte in Australia – a key component of the increasingly popular vanadium redox flow batteries.

Redflow has signed its biggest global battery deal yet after agreeing to supply Californian biowaste tech firm Anaergia with a 2 MWh energy storage system. Redflow is hoping the US$1.2 million agreement for 192 of its zinc-bromine flow batteries will serve as a foundation for US market expansion.

The Australian Renewable Energy Agency is helping to fund a trial by Distributed Energy Resources firm UPowr which will monitor solar customers interested in incorporating a home battery system. The aim of the project is to better incorporate customer experience insights into the design of DER products.

Scientists in China and the United States investigated the inner workings of aluminium-ion batteries. With new insights into mechanisms at work within the battery during cycling, the group was able to demonstrate a battery capable of ultrafast charging, with the highest capacity so far reported for an aluminium battery.
