Novel algorithm estimates global maximum power point in partially shaded PV systems
Developed by scientists in India, the global maximum power point (GMPP) technique is based on the voltage and current of strings in a PV array. The research group tested it in computer simulation, as well as through an experimental setup.
Natural hydrogen drill leads to deals fast-tracking Australia’s first gold hydrogen project
Following promising initial drill results from its Ramsay natural hydrogen project, Gold Hydrogen has signed two industry deals to collaborate on a proof-of-concept natural hydrogen pilot on South Australia’s Yorke Peninsula. If successful, it would be Australia’s first natural hydrogen project.
Australian researchers delve into lithium microstructures causing catastrophic battery failures
Researchers from the Australian Nuclear Science and Technology Organisation (ANSTO) have used advanced neutron scattering techniques to better understand what leads to catastrophic failures in lithium ion batteries.
Hydrogen-powered vertical takeoff aircraft from Sydney startup backed by ARENA
Sydney startup AMSL Aero has been awarded $5.43 million by ARENA to develop a hydrogen-powered electric aircraft capable of taking off and landing vertically. The startup has previously flown a battery-only prototype, but says adding a hydrogen fuel cell will increase the range to 1000km.
New land, water licenses granted for 8 GW green hydrogen project in WA’s Gascoyne
Province Resources, a Perth-based company developing an 8 GW green hydrogen project in the state’s Gascoyne region, has had additional licences granted by the WA government covering an area over 600,000 hectares, including over 864 hectares of the seabed near Carnarvon needed for export.
BYD unveils new agrivoltaics module

Longi claims 33.9% efficiency for perovskite-silicon tandem solar cell
The US Department of Energy’s National Renewable Energy Laboratory (NREL) has confirmed Longi’s achievement of a world record-breaking efficiency rating of 33.9% for a perovskite-silicon tandem solar cell.
Canberra big battery significantly delayed due to connection compliance issues
Neoen’s Capital battery project in Canberra is facing significant delays due to connection compliance testing, with the company flagging potential for it to pursue damages from EPC contractor Doosan GridTech. The completed battery was expected to be operational in early 2023.
NSW coastal council and volunteers to repurpose secondhand solar panels locally
A council on the NSW South Coast is prioritising the reuse of solar panels, partnering with a volunteer community group to either gift or resell the panels locally.
Queensland Bouldercombe battery fire ignited on grid side, not within Megapack, analysis finds
Genex Power, owner of the 50 MW / 100 MWh Bouldercombe battery which caught fire in Queensland on September 26, says its preliminary root cause analysis found the fault occurred at the grid side of the Tesla Megapack battery unit.
