Distributed Storage

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.

Battery storage manufacturer RedEarth has partnered with a major Australian housing developer to offer new-home buyers solar and solar/battery systems tailored to their needs from the get go – and with the opportunity to sell excess energy at optimised prices where the grid needs it most.

Japanese scientists are about to launch solid-state batteries into space.

Lithium-ion batteries can not only improve self-consumption in commercial PV systems but are also able to efficiently perform peak shaving and price arbitrage, according to an international research group which has proposed a new strategy to calculate the best system configuration in terms of costs and revenue. The scientists specified, however, that the novel strategy may become effective only if storage system prices will drop under $250/kWh.

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.
