Sydney’s Northern Beaches Council has seen its energy costs slashed by switching to renewables.

Speakers at the CEC All-Energy conference in Melbourne have prioritised the built environment as ripe for embedding higher efficiency and sustainability standards.

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.
