ANU’s Dr Bjorn Sturmberg has launched his book Amy’s Balancing Act, a fable about Australia’s energy transition. While, of course, for kids, Dr Sturmberg’s book gestures towards fundamental questions for the industry itself. The energy transition is not just a technological shift, he tells pv magazine Australia, but systematic and emotional one – facets often overlooked within the industry.

Boundary Power, a union between West Australian standalone power system (SAPS) leader Horizon Power and Ampcontrol, has installed its first off-grid system for an unnamed east coast utility in regional New South Wales.

Researchers from RMIT and the University of Melbourne have discovered high-frequency vibrations can release 14 times more hydrogen compared with standard electrolysis techniques. The discovery also has ramifications for the expensive, rare materials currently used in electrolysers. “With sound waves making it much easier to extract hydrogen from water, it eliminates the need to use corrosive electrolytes and expensive electrodes such as platinum or iridium,” research lead Amgad Rezk said.

Chinese battery maker Hithium and Australian solar developer Sun Valley HK Group have agreed to work together on eight solar farms either under construction or in planning in Australia, presumably deploying Hithium batteries at the sites.

The cost of megaprojects is becoming increasingly difficult to estimate, which is causing budget blow outs. Analysis by the Grattan Institute shows that governments in Australia spent $34 billion more on transport infrastructure than first estimated, and that there was a 21% total cost blowout of $20 million-plus projects in the past 20 years. This is a strong example of the need for chief financial officers (CFOs) to participate in managing the cost of inflation through improved communication with stakeholders across supply channels.

Renewable energy developer Lightsource bp will begin full construction activities on two large-scale solar projects with a combined installed capacity of 515 MWdc in Australia after successfully closing a $540 million (USD 365 million) financing package.

Another of the coordinated clean energy zones planned for New South Wales is a step closer to being developed with the state government announcing the Hunter-Central Coast Renewable Energy Zone, which has already attracted expressions of interest for almost 40 GW of generation, has been formally declared.

Researchers from UNSW have discovered a low-cost way to stabilise perovskite solar cells with a “triple function, cheap additive,” research lead Professor Hao tells pv magazine Australia. Perovskite cells using the additive have returned the best stability results yet seen in Australia, according to the team, and among the best in the world.

Australian technology start-up Infravision will team with New South Wales network operator Transgrid in a trial of a “next generation” line-monitoring system designed to optimise the performance of existing electrical transmission infrastructure and support the roll out of more renewable energy.

New South Wales network operator Ausgrid has signed an agreement with Simply Energy which will see the Melbourne-based energy retailer operate the electricity distribution company’s three community batteries in the National Energy Market.
