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.
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.
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.
New method to measure energy yield of bifacial PV systems
Canadian scientists have developed a new way to measure the energy yield of bifacial PV systems. They said they considered the spectral albedo of ground cover like snow and sand to predict energy gains of up to 2%, in comparison with the International Electrotechnical Commission (IEC) standard.
Adapting agrivoltaics to different climates, crops
An international consortium led by Italy’s Eurac Research launched the Symbiosyst project to adapt PV modules, mounting structures, and maintenance technologies to the needs of various crops in agrivoltaic installations in different climates.
Educational events for engineers upskilling for hydrogen industry begin in Victoria
An educational event series aimed at upskilling engineers to enter the hydrogen industry is launching in February in Melbourne. The Hydrogen Industry Technical Series 2023 is being organised by the Victorian divisions of the Australian Institute of Energy and Engineers Australia.
Vertical agrivoltaic pilots in France find improved yields and less water stress
French energy giant TotalEnergies studied the impact of solar panels on crops in order to develop a repository of agronomic benefits. The initial results show an increase in agricultural yields on field crops and a reduction in water stress.
Brisbane battery casing startup with ‘tremendous potential’ lands support from ReNu
Queensland-based ReNu Energy will acquire up to a 20% stake in fellow Brisbane company, startup Vaulta, which has developed battery casings designed for reuse and recycling. Vaulta will use the eventual $1 million (USD 700,000) investment from ReNu to scale its manufacturing capability and expand domestic and offshore sales.
