The comparison of two solar cladded roofs in Sydney, one bare beneath its panels and the other adorned with native grasses and plants, has found the panels on the green roof were, on average, 3.63% more efficient, producing an average daily output 13% greater than the conventional roof. The improvements are believed to stem from the lower temperatures on the green roof, thanks to its plants – which also provided a plethora of additional benefits.

Australia’s Commonwealth Scientific and Industrial Research Organization plans to use its Newcastle Energy Centre – home to the largest high-concentration solar array in the Southern Hemisphere – as a demonstration site for its newly announced net-zero emissions targets.

Australia has the sun, the wind and the space to become one of the world’s green hydrogen export superpowers in coming decades. However, the Sunburnt Country does have a dearth of one ingredient in the green hydrogen equation – freshwater. Thankfully, researchers from Monash University and a group of national water utilities are joining forces to find a way to use wastewater for the process of electrolysis.

Researchers at The Australian National University claim to have set a world record for bifacial solar PV cell efficiency that they say could boost the energy output of solar farms by 30%.

Researchers at Monash University have published a new study in which high voltage lithium batteries, such as those used in electric vehicles and grid scale energy storage systems, are tested with a novel lithium salt shown to be far less hazardous than current conventional materials.

Three PhD students from Melbourne are moving their research into recycling lithium-ion batteries from the labs into pitch meetings, vying to become one of the first companies in Australia to recover the metals and minerals from spent batteries. Their method, they say, is simpler, less toxic and more cost competitive than those widely used.

German scientists have applied a new combination of cathodes and electrolytes to improve the stability of lithium-metal batteries. They fabricated a device with an energy density of 560 watt-hours per kilogram and a Coulombic efficiency of 99.94%.

Younger students have been denied an understanding of fundamental physics that would inform their understanding of today’s most pressing scientific problems and how to solve them. A group of scientists has reimagined the classroom as an engaging, enabling hub of investigation and discussion.

A new study from Stanford University and Cornell University shows that blue hydrogen can produce more greenhouse emissions than heat produced by coal and gas. The modelling classifies blue hydrogen emissions as carbon dioxide and unburned fugitive methane, as well as lifecycle emissions linked to the mining, transport, storage, and use of methane.

Alan Tudge, Australia’s Minister for Education and Youth, last week announced new grant outcomes under the ARC Future Fellowships scheme. Recipient Professor Anita Ho-Baillie will directly apply her work on perovskite durability and resilience to more cost effectively powering the world’s space endeavours.
