The Australian Government has committed more than $240 million to critical minerals projects in a bid to end Australia’s reliance on China and cement its place in the rapidly growing global electric vehicle and battery markets.

Researchers in Spain have designed a pumped thermal energy storage system that uses supercritical carbon dioxide as a heat pump and a heat engine. The proposed system is claimed to achieve an efficiency of 80.26% and an LCOS of €0.116/kWh (AU$0.18/KWh)

A report published by IRENA hints the world’s politicians will have to get to work immediately to avoid another generation of fossil fuel-fired hydrogen, ammonia, and methanol plants being set up to run into the second half of the century.

German luxury carmaker Mercedes-Benz has made public its plans partner with Primobius, a 50:50 joint venture between West Australian company Neometals and Germany’s SMS Group. Mercedes has said its intention is to build a 2,500 tonne per year lithium-ion battery recycling plant in southern Germany with Primobius as its technology partner.

The world has installed its first terawatt of hardware on earth to generate electricity directly from the sun.

Federal Labor has promised to allocate $22 million to help establish the Lansdown Eco-Industrial Precinct being developed in northern Queensland if it wins the election in May.

A multibillion-dollar solar, battery storage, wind and potentially green hydrogen project in Victoria’s Gippsland region is moving forward after getting backing from superfund Hostplus. Originally proposed by Solis Renewable Energy, the project is now owned by Octopus Australia as part of its joint venture with CFEC.

Sodium-ion batteries are emerging as a viable alternative to lithium-ion technology. Industrial heavyweights CATL and Reliance Industries, following the acquisition of UK-based sodium-ion specialist Faradion, are bent on bringing the technology out of the lab and into mass production. Against a backdrop of soaring prices and predicted shortfalls of lithium-ion battery materials, sodium-ion chemistry has never been more tantalising.

Australia has set renewable energy records for the fifth consecutive year with new data showing clean energy accounted for nearly one-third of the electricity produced in the National Electricity Market in 2021, with the continuing roll out of rooftop solar PV spearheading the switch away from traditional fossil-fuel generation.

Mine sites across Western Australia are decarbonising after Zenith Energy and modular solar pioneer 5B signed an Ecosystem Framework Agreement-Deployment, which will see 5Bs rapidly deployable Maverick solar systems installed along with battery energy storage systems at multiple mine sties.
