For the first time in the history of our national energy market, solar generated more electricity than coal, providing 41.4% of the national market on Sunday, while coal accounted for 41.2%.

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.

Carbon never goes away, says Associate Professor Tianyi Ma, but if industrial carbon-dioxide emissions can be cleanly, renewable catalysed into chemicals and fuels that we need, we can reduce the overall GHG burden on the earth’s atmosphere.

Developed by the Korea Institute of Energy Research (KIER), the “non-destructive” technology is claimed to enable the recovery of 100% of a module’s glass and to allow the reuse of silicon for producing new solar cells with an efficiency of 20.05%.

As technology redefines the delivery of network services, grid operators in remote areas the world over are searching for more cost-effective and reliable alternatives to traditional poles and wires. Standalone power systems are the solar application that is at the forefront of the switch, and they’re ramping up fast.

The Australian Energy Market Operator will later this month commence testing of a cloud-based simulator designed to accelerate the grid connection process for developers of energy projects including large-scale wind and solar.

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.

Halide perovskites combined with conventional silicon could help solar break the 26% efficiency barrier – disrupting the technology without disrupting business systems.

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.

Next Energy and Marubeni are developing a blockchain tech for PV module inspection – with the support of the Japanese government – which they claim is able to provide data on a panel’s traceability and components as well as verifying that the data were not modified or tampered with.
