Energy Storage

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.

Before beginning BESS design, it’s important to understand auxiliary power design, site layout, cable sizing, grounding system and site communications design.

Virtual Power Plants, or VPPs, are relatively mature in Australia due to the country’s high penetration of, and familiarity with, distributed energy resources. But claims of VPP success and participation may be overblown, with a considerable gaps between the numbers some platforms are claiming and the realms of possibility.

Australia’s lithium and base metals like nickel, aluminium and copper are forecast to earn around $47 billion (USD 31.8 billion) in the current financial year, according to the Australian government’s latest forecasts.

Brisbane company Li-S Energy has developed its third-generation semi-solid state lithium sulfur battery cells. The 20-layer cells, produced in its facility in Victoria, are lightweight and energy dense, reaching over 400 Wh/kg.

Storage specialist Fluence has launched Ultrastack, a battery energy storage system (BESS) for storage-as-transmission assets. It is designed to help network owners and operators to manage renewables curtailment, increase the use of power lines, and limit congestion.
