Recycling process promises ‘better than new’ silicon wafers

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.

High-wattage solar modules increase risk of thermal runaway

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

Weekend read: keeping FPV afloat

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 Power reaches milestone in off-grid program

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.

WA company expects green hydrogen production ‘significantly earlier’ than anticipated following promising study

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.

Lithium-ion vs. vanadium redox flow storage

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 secures financing for series of grid forming batteries in NSW

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.

Hydrogen combustion tech for residential water heaters, trials in Australia

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.

New model for grid-forming inverter operation

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.
