Scientists unveil dirt-repellent coating for solar panels
Researchers from Germany’s Fraunhofer FEP have unveiled a dirt-repellent coating for solar panels. The material is reportedly able to acquire superhydrophilic properties at night and wash away accumulated dirt with the aid of beads of moisture.
Risen reveals big battery plans for regional NSW
In pursuit of its Australian target of developing 3 GW and delivering 1 GW of renewable projects by 2027, China-headquartered PV module manufacturer and project developer Risen Energy has unveiled plans to develop a 100 MW/400 MWh battery in regional New South Wales.
Scientists source silicon from solar waste to build better batteries
Researchers from Victoria’s Deakin University say they have successfully tested a new process that can safely and effectively extract silicon from end-of-life solar panels, then convert it into a nano material worth more than $45,000 (USD 31,500) per kilogram that can be used to build better batteries.
Storing renewables via regenerative braking in underground mines
Scientists in Austria have developed a long-term energy storage system that uses regenerative braking to adjust the descent speed of sand in mine shafts and generate electricity.
New digital solar tool launches promising to save customers from aggressive sales tactics
Australian climate tech platform Acacia will launch a new solar feature enabling customers to get a digital solar quote, as well as estimated financial and carbon savings, without speaking to any sales people. The company says the tool is in response to what are often poor buying experiences in the solar sector.
Queensland to build $75m vanadium, rare earth processing facility for burgeoning battery industries
The Queensland government will invest $75 million (USD 53 million) to expand a critical minerals demonstration facility in Townsville – a project it claims will be an Australian first. The facility, slated for operations in 2025, is part of a growing push in Australia to develop battery materials industries beyond simply mining.
Construction begins on 93 MW Victorian solar farm as owner plans first hybrid venture
Construction has now begun on the 93 MW Girgarre Solar Farm in central Victoria, about 70 kilometres west of Shepparton. The project has been in development for at least five years, and was initiated by Leeson Group’s founder and director, Peter Leeson, before being sold to Enel Green Power in 2019.
Saltwater flow battery for large-scale storage unveiled from US startup
US-based Salgenx has developed a scalable redox flow battery with two separate tanks of electrolytes, one of which is saltwater. Unlike other flow batteries, the new device is membrane-free, promising big gains at the levelised cost of storage level.
Key takeaways from Abu Dhabi’s World Future Energy Summit
The World Future Energy Summit showed that Middle Eastern solar markets are still driven by utility-scale PV, although the C&I sector shows signs of growth. Saudi Arabia, Egypt and the United Arab Emirates are the most promising markets for big solar projects, with huge pipelines under development, while Lebanon and Yemen show promise due to chronic energy shortages.
Queensland flow battery maker integrates products with Chinese inverters
Queensland zinc-bromine flow battery maker, Redflow, has announced its batteries have successfully been integrated with Chinese brand Deye’s hybrid inverters. Redflow says the integration “provides a range of new capabilities previously unavailable to the Australian market.”
