The beleaguered Snowy 2.0 pumped hydro project has been hit with fresh construction delays and added cost blowouts with concerns the multi-billion-dollar project may now not reach full commercial operation until late 2029.

The successful projects from the first tender conducted under the New South Wales government’s Electricity Infrastructure Roadmap have been announced with two large solar farms, a wind farm and an eight-hour battery energy storage system to be built as the state looks to manage the exit of coal-fired power generation from the grid.

Western Australian startup International Graphite says its proposed graphite processing plant in Collie has been found to have “outstanding” economics by its new scoping study. Graphite is a vital element in lithium-ion batteries and International Graphite is one of a handful of Australian companies working to move its processing onto Australian shores.

Chinese battery industry heavyweight CATL has unveiled a novel condensed matter battery technology with an energy density of up to 500 Wh/kg. The company said it can achieve mass production within this year.

Origin Energy will “within weeks” begin building the first stage of a planned 700 MW/2,800 MWh grid-connected battery energy storage system being developed at the site of Australia’s largest coal-fired power plant that is set to be shut down in less than 28 months.

Australia’s transition to clean, renewable energy has reached a major milestone with AGL today commencing the process of shutting down the last of three coal-fired generating units still operating at its Liddell power station in New South Wales as it prepares to completely close the facility before the end of the month.

Salgenx has developed a way to produce graphene on demand from its saltwater flow battery. The tech exploits the electrochemical properties of the battery’s cathode to exfoliate graphite into individual layers of graphene. The company says it can produce graphene for less than USD 1.25 ($1.85) per gram, providing storage businesses with an additional revenue stream.

Venture capital fund Macquarie Group’s new battery storage platform Eku Energy has been tapped by the Australian Capital Territory government to deliver the next stage of the Big Canberra Battery ‘ecosystem’ which will support the ongoing rollout of large-scale renewables and rooftop solar.

Tesla has revealed plans to build a new Megapack battery factory in Shanghai, according to the Xinhua news agency.

Scientists in Italy have looked at how flywheel storage and reversible solid oxide cells could be integrated with lithium-ion batteries in minigrids powered by solar. They found that flywheels combined with batteries could be the cheapest option for power smoothing.
