A team of researchers from the University of New South Wales (UNSW) has proposed a cost-effective way to recycle silicon solar panels. Their process consists of module deframing, laminate shredding and material concentration using electrostatic separation, reducing their original weight by 2% to 3%.

The Victorian government has announced an ambitious target to reach 95% renewables by 2035, to end the state’s reliance on coal generation, and to establish a publicly owned corporation that will see the state hold a controlling stake in new renewable energy projects.

University of New South Wales researchers have teamed up with Tindo Solar to develop a line of semi-transparent modules, specialised for agrivoltaic cropping, which will use nanoparticles tuned to capture different parts of the light spectrum. “There is evidence you don’t need the full spectrum and some plants will work even better if you provide them with only part of the spectrum,” project lead and UNSW Associate Professor Ziv Hameiri tells pv magazine Australia. Crucially, he says, the project will also open a line between farmers, solar researchers and industry, creating the potential for mutual benefits.

Shell Energy Australia has been awarded $9.1 million from the Australian Renewable Energy Agency to recruit at least 40 commercial customer sites, including shopping centres and supermarkets, to begin shifting how and when they use electricity – a demonstration of the potential of flexible demand.

A 2.8 GW solar-powered green hydrogen export project being developed on the Tiwi Islands in the Northern Territory has taken the next step towards securing environmental and planning approval with developer Provaris Energy lodging an assessment referral with the federal government.

The head of the country’s energy market operator has reiterated his call for the development of a mechanism that incentivises dispatchable capacity, saying it is critical to underpin the growth of renewables as Australia’s energy transition continues to accelerate.

A study of the investment and innovation needed to achieve the European Green Deal’s aviation ambitions has highlighted the key role that synthetic fuel can play until hydrogen and electric flights become a reality.

Islandable microgrids are a growing niche, especially in remote regions at the end of electricity networks or parts of the world prone to natural disasters and outages. Renewably powered microgrids can provide a community with more stability and operate independently, so vulnerable regions are not reliant on distant sources of generation, as was the case during Australia’s Black Summer bushfires of 2019-20, when communities were left powerless. From California to Australia’s southern coast, the study and deployment of microgrids is on the rise. pv magazine’s Blake Matich takes a look.

Plans to build one of the world’s largest renewable energy powered electrolysers in Queensland continue to gather pace with the Australian Renewable Energy Agency awarding $13.7 million (USD 8.8 million) to the proponents of the project to help finance a $38 million front-end engineering and design study.

Six new solar farm projects totalling 623 MW of renewable capacity and four big batteries delivering up to 365 MW and 600 MWh of new energy storage have been given the tick of approval by the Victorian government as it looks to meet its target of powering all its operations with clean energy by 2025.
