Researchers in the United Kingdom have developed a new method of extracting silver and aluminium from end-of-life PV cells using iron chloride and aluminium chloride dissolved in brines. According to the research team, the cheap solvents retrieve up to 95% of the metals within 10 minutes, achieving a 98% purity of silver chloride.

Victoria’s ongoing transition to renewable energy sources, including the installation of hundreds of thousands of rooftop solar PV systems, has helped the state “smash” its 2020 emission reduction targets on the path to net zero by 2050.

Transitioning from fossil fuels to renewable energy technologies including solar PV and green hydrogen by 2050 could save the world at least $18 trillion (US$12 trillion), according to a peer-reviewed study published by researchers from Britain’s Oxford University and Australia’s Monash University.

Crypto mining electricity use can exceed that of large, developed nations. Solar and storage can help cut carbon impact, but could the power be best used elsewhere?

Perth-based battery technology company Lithium Australia’s 100%-owned subsidiary Envirostream has ramped up its battery recycling efforts, signing an agreement with South Korean manufacturer LG Energy Solutions to process at least 250 tonnes of its lithium-ion batteries over the next year.

Australia’s federal government has trumpeted the successful passage of legislation enshrining a pledge to slash carbon emissions by 43% by 2030 and to net zero by 2050, saying it provides the certainty that investors have been seeking so they can invest in renewable energy generation, storage and in transmission.

The Queensland government is reportedly considering ramping up its renewable energy target as the state looks to wean itself off coal-fired power on the pathway to net zero emissions by 2050.

Brisbane-based bioenergy company LGI Limited has listed on the ASX, seeking to raise $25 million for expansions, including fitting sites with batteries capable of playing on spot markets. For the company’s founder, Adam Bloomer, the role of bioenergy in Australia only makes real sense when limited to waste. “If it’s is not a waste stream, I think you’re barking up the wrong tree,” he tells pv magazine Australia.

Australian gas company APA Group has signed a third offtake agreement for its 88 MW Mica Creek Solar Farm, currently under construction in Queensland’s mining hub.

As Australia’s Climate Change Bill 2022 progresses through parliament, a Senate committee has recommended using wood waste from native forests to generate electricity should no longer be classified as “renewable energy.” It is not yet clear what impact such changes would have on the growing pipeline of Australian ‘biomass’ projects.
