In aviation news, Qantas has announced a partnership with Airbus to invest up to $285 million to establish a sustainable aviation fuel industry in Australia. Meanwhile, startup Aviation H2 says it is in the process of acquiring test engines it will modify to run on hydrogen, which are due to arrive in the next five weeks.

Scientists in China have developed a new recycling process for PV modules that can recover intact silicon cells from end-of-life products, and process them back into wafers. As part of the recycling process, the wafers are purified and surface-treated, making them suitable for integration into new, high-efficiency cells and modules.

Longi Solar outlines its high-temperature mitigation logic in designing the lower current, high-wattage Hi-MO5 solar panel series.

In many parts of the world, project developers and owners are increasingly looking to floating PV as the next long-term growth market in utility-scale solar. Gian Schelling, global business development manager for Hitachi Energy, says that PV-on-water can rise above the current challenges it faces by drawing on the lessons learned from offshore wind development.

Western Australia’s regional utility Western Power has confirmed plans to install another 4,000 standalone power systems across the state in the next 10 years after reaching a milestone in the rollout of the renewable energy units.

Western Australian developer Frontier Energy, a relatively new player in the renewable space, says preliminary findings from its green hydrogen study indicate it could be producing “significantly earlier than originally anticipated” from its Bristol Springs Solar Project, to be located south of Perth.

UK scientists have compared the performance of lithium-ion storage systems and vanadium redox flow batteries for a modeled 636 kW commercial PV system in southern California. They have found that both technologies, coupled with an oversized PV array, could achieve a levelised cost of electricity of less than US$0.22/kWh (AU$0.32/kWh), while offering a self-sufficiency ratio of 0.95.

Edify Energy has completed the financing for its grid forming 150 MW / 300 MWh battery energy storage system. The system will be made up of three separate batteries in the Riverina region of NSW which have gained approval to operate in ‘virtual synchronous generator’ mode.

Japan’s Rinnai has unveiled what it claims is the world’s first 100% hydrogen combustion technology for residential water heaters. It is currently using the hydrogen water heater in demonstration projects in Australia, prior to commercialisation.

Scientists in the United States have developed a new model to allow utilities to use grid-forming inverters in order to better manage renewable energy intermittency. They describe the inverter main circuit representation, the droop control, and the fault current limiting function.
