The European Patent Office says China has overtaken other countries in photovoltaic patent filings over the past 15 years, while European startups and universities retain a lead in agrivoltaics and niche solar applications.

Transgrid has chosen grid-forming batteries and synchronous condensors as its preferred system strength technologies, as coal generators retire over the next decade and renewable energy supplies the state.

Scientists in India have simulated and tested a prototype wireless charging system for electric vehicles, with a three-port DC–DC converter at its core and have found it achieved an improved efficiency of 88%.

ClearVue Technologies says its solar facade solutions, that combine the company’s solar glazing units into a fully integrated energy generating building envelope, have achieved a payback period of less than three years in a Hong Kong government trial.

Printed solar technology startup Kardinia Energy, photoluminescence imaging specialist BT Imaging, and modular solar array manufacturer 5B are among 13 companies awarded more than $26 million in funding by the New South Wales government to support the commercial development of their clean energy tech.

To evaluate the outdoor performance and stability of perovskite solar cells using contactless and noninvasive methods, an Australian and Chinese research team found a way to use photoluminescence imaging as well as demonstrating a proof of concept for implied open-circuit voltage imaging. Their research relied on cost-effective equipment that operates under direct sunlight.

Mining giant BHP has struck early-stage agreements with two of the world’s largest battery manufacturers to explore the application of battery technology and electrification across its global operations.

Researchers in Singapore have milled solar panel glass waste for use in cathodes in solid-state lithium metal batteries. When used as a functional filler in solid polymer electrolyte (SPE) material, the resulting battery performance was maintained over 80 charge cycles with an 8.3 % improvement over the reference device.

New large-scale solar farms in Australia’s southeast could be forced to curtail up to two thirds of their power generation by 2027 due to delays in energy transmission infrastructure projects, according to new analysis from the Australian Energy Market Operator.

Li-S Energy has produced Australia’s first lithium metal foils at its cell production facility in Victoria, a milestone the company says supports its broader mission to commercialise high-performance lithium-sulfur and lithium metal batteries.
