US scientist have developed a new electrolyte design for sodium-ion batteries to improve their long cycling performance. The low-solvation electrolyte was designed for high-voltage sodium-ion batteries, which retained 90% of their capacity after 300 cycles.
Recycling solar panels keeps them out of landfills, but also provides much-needed raw materials with Rystad Energy projecting a value approaching AU$118 billion (US$80 billion) by 2050.
Speaking at the Sydney Energy Forum, leaders from Australia and the US have highlighted the importance of not only transitioning to renewables, but of ensuring the supply chains used to make the technologies do not remain as concentrated as they are today.

Salient Energy developed the water-based zinc-ion battery to have the same power, performance, and footprint as lithium-ion systems without the safety risk.
Thin-film cadmium telluride panels may have a US$0.02 to US$0.04 per watt carbon cost advantage over traditional polysilicon, said the National Renewable Energy Laboratory in an analysis of embodied carbon, embodied energy, and energy payback.
Australian company AspiraDAC, which uses solar powered Direct Air Capture (DAC) technology to remove carbon from the atmosphere, has been selected to be part of the first round of purchases from Frontier, a program backed by Facebook and Google’s parent companies, Meta and Alphabet.
Stanford University scientists have built an optical concentrator that purportedly harvests more than 90% of the light that hits its surface.
Alion Energy trackers thread the return-on-investment needle with productivity gains from white roofs and bifacial modules, while design aggressively maximises module count.
Rio Tinto has joined a group of industrial heavyweights including Equinor, Amazon and Mitsubishi Heavy Industries as investors in United States-based renewable hydrogen start-up Electric Hydrogen which plans to build green hydrogen production facilities at scale for industrial and infrastructure applications.
