Distributed Storage

The device is described as a heat engine with no moving parts that is able to produce power from a heat source of between 1,900 to 2,400 C. This concept is known as thermal energy grid storage (TEGS) and consists of a low-cost, grid-scale storage technology that uses thermophotovoltaic cells to convert heat to electricity above 2,000 C.

Bromine-based flow batteries have the potential for high energy density in renewable energy storage. Their commercial adoption, however, remains challenging due to the cathode materials used for their construction. New research from China seeks to shed light on how to overcome these hurdles.

Global solar supply chain issues and the Chinese energy crisis which hit in the second half of last year have, ironically, led to a “massive” oversupply of solar panels in Australia, according to major distributors. The tension between increased global panel costs and the glut of them within Australia has led to some messy pricing and strange market dynamics on the ground.

Developed by Dutch start-up AquaBattery, the storage technology is claimed to independently amend power and energy capacity. The battery system utilises three storage tanks, one with fresh water, one with concentrated salt water and one with diluted salt water, and also relies on membrane stacks.

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.
