Western Australia-based Altech Chemicals’ plan to develop a high-grade alumina coating plant for lithium-ion batteries in Germany has taken a crucial step forward with the acquisition of an industrial site that could potentially house the facility.

Scientists in Australia have analysed the state-of-the-art of all gettering technologies used in the solar industry. This technique, which is aimed at reducing defects in wafer manufacturing, may become more important in the future, as cell efficiencies increase and become increasingly sensitive to traces of metallic impurities.

Researchers in Switzerland have replaced the electron transport layers in perovskite solar cells with a thin layer of quantum dots. On an area of 0.08cm2, they achieved a record efficiency of 25.7% and high operational stability.

A 100kW/1.5MWh zinc-air battery will be installed in Queens, New York, in combination with a combined heat and power system and a PV array. The pilot project is intended to demonstrate the long-duration energy storage capability of the zinc-air battery.

Growatt’s new AXE LV battery covers a wide range of capacities, from 5kWh to 400kWh, and can support off-grid systems with power outputs of 3kW to 30kW.

Gold developer Calidus Resources has become the latest miner to decarbonise its Western Australian operations by installing a 19 MW hybrid solar PV-gas power system which in future could be up to a quarter fuelled by hydrogen.

The debate around what’s become known as Australia’s “solar tax” has rounded a new corner, with the Australian Energy Regulator publishing its draft guidelines for solar export tariffs.

Researchers from the University of New South Wales (UNSW) predict that growth to 60TW of photovoltaics needed to rapidly reduce emissions to ‘net zero’ and limit global warming to <2 °C could require up to 486 Mt of aluminium by 2050. A key concern for this large aluminium demand is its large global warming potential.

Humes, a division of concrete company Holcim Australia, is making moves on its emissions reductions targets with the installation of rooftop solar on 10 of its sites across Australia. With a number of the projects already completed, Humes expects to finish the large-scale layout by the end of March 2022.

Prospective hydrogen projects in the Northern Territory are taking new shape with Monday’s news that FRV Australia, partially owned by now Saudi company Fotowatio Renewable Ventures, had signed an agreement with Australia’s Hexagon Energy. It seems the two companies are considering connecting the hydrogen projects they’ve been separately exploring near Darwin, though it’s worth noting Hexagon is hoping to export blue (fossil) hydrogen.
