Distributed Storage

The amount of solar installers offering storage solutions grew considerably in 2021 and promises to surge again this year, according to an annual survey by EUPD Research. The research centre has also released the top three 2021 brands for solar modules, inverters and storage in the Australian market, offering insights into where companies are buying equipment and which segments are seeing the most growth.

Chinese inverter maker Growatt has launched Infinity 1500, a portable power station for off-grid applications.

Over 90% of Australia’s fuel is imported – something recent geopolitical events have illustrated is a serious vulnerability. This issue was the focus of an emergency fuel security summit held yesterday in Sydney. The event was attended by a number of industry leaders and independent members and candidates who put forward solutions to tackle the devolving situation.

Japan’s Panasonic claims its new pilot solar-plus-hydrogen facility marks the first attempt to create a factory powered by 100% renewables, via the full-scale use of hydrogen.

Developed by a Chinese-Swedish research group, the device is an ultra-thin chip that could be integrated into electronics such as headphones, smartwatches and telephones. It combines a Molecular Solar Thermal Energy Storage System (MOST) with a micro-fabricated system that includes a thermoelectric generator (TEG) with a low-dimensional material-based microelectromechanical system (MEMS).

Australia’s inventories of critical materials for batteries have seen major increases recently, with vanadium up 23%, lithium up 8%, rare earths up 4% and platinum group elements up 185% in the year to December 2020.

The device is based on a standard, two-electrode electrochemical cell containing conductive polymers, a carbon-graphene hybrid, and a non-flammable liquid electrolyte. The battery cells were tested to perform for 12,000 cycles at 100% depth of discharge.

A major Western Australian mine targeting the global vanadium battery market was this week found to be bankable, with feasibility studies confirming the project’s “strong commercial case for development,” its owner Australian Vanadium Limited said.

To encourage industry to consider the battery mineral opportunities currently sitting in neglected heaps around the country, Geoscience Australia and its partners are developing an Atlas of Australian Mine Waste. The public database hopes to highlight the opportunity in reprocessing mining waste for new markets.

The global battery energy storage market will grow to US$10.84 billion (AU$14.54 billion) in 2026, with around two-thirds of the demand concentrated in the Asia Pacific region.
