Distributed Storage

Battery-maker, retailer and financier alliance sees more players enter Australia’s VPP space

South Korean company LG Energy Solution has partnered with Australian fintech financier Humm Group and renewable energy retailer Diamond Energy to provide customers with Virtual Power Plant platform. Virtual power plants (VPPs) are gaining momentum in Australia as a way to decrease buyback time on home batteries and potentially add stabilisation services to the grid.

A closer look at liquid air energy storage

A British-Australian research team has assessed the potential of liquid air energy storage (LAES) for large scale application. The scientists estimate that these systems may currently be built at a cost between €300 and €600 (AU$480 to $960) per megawatt-hour and that a positive business case could be favoured by certain conditions, including a determined price structure in the energy market and the presence of a grid unable to support high levels of renewable energy penetration.

Sodium-ion batteries a commercial reality, claims CATL

The manufacturer has launched sodium-ion products online. Production has begun and will be easily scalable, according to the CATL chairman. Researchers have been keen to make the technology work as it offers a cheaper, more environmentally friendly alternative to lithium-ion products.

Saturday read: In conversation with UNSW’s Anna Bruce on distributed transformation

The time is now for the energy consumer, says Anna Bruce, as energy “prosumers” produce, consume, and provide electricity and grid services in previously unimagined ways. Bruce, a senior lecturer at the University of New South Wales’ School of Solar Photovoltaic and Renewable Energy Engineering (SPREE), leads work on the role of distributed energy resources in the energy transition, analysing firsthand the dizzying level of complexity it brings.

Federal government launches Battery Stewardship Scheme

Assistant Minister for Waste Reduction and Environmental Management, Trevor Evans, has announced a newly accredited Battery Stewardship Scheme that he says will triple the battery collection rate over a period five years and divert 90% of the collected materials from landfill. 

Partnership to explore hydrogen technology in standalone systems

Standalone power system specialist Boundary Power has teamed up with Australian hydrogen technology company LAVO to investigate the potential application of its renewable hydrogen energy storage system in power solutions suitable for off-grid and edge-of-grid customers.

Commercial and industrial rooftops in India could deploy 1,875 MW of solar in 2021

According to a new report, India’s commercial and industrial sectors will increase their rooftop solar deployments by 47% year-on-year, with bifacials and large-size high-wattage modules offering cost-effective support for reducing electricity costs.

‘Stick-on’ solar panels in France secure EU funding

The TotalEnergies-controlled solar manufacturer will secure an, as yet undetermined chunk of a new €118.6 million low-carbon innovation fund to start producing its frameless, glass-free solar roofing products at Porcelette, in northeastern France.

Aussie startup invents breakthrough non-toxic battery electrolyte that’s cheaper ‘by factor of 100’

It’s a breakthrough so staggeringly simple the patent office needed convincing it counted as an invention. In what Professor Thomas Nann jokingly told pv magazine Australia basically equates to adding dishwashing liquid and oil to water, he and two of his former PhD students have unlocked the potential of water-based electrolytes for batteries, promising a solution that is cheaper, easier to manufacture and non-toxic. The startup plans to initially use the formula in supercapacitors before exploring it in conjunction with redox flow batteries.

Queensland energy survey reveals shifts in battery and EV embrace coupled with continued love of solar

Households with residential batteries have doubled in Queensland in the last two years, though cost remains a barrier – as it has with electric vehicles. As prices fall, however, the state is likely to welcome the technology with open arms, as it has with solar. 37% of Queensland households now harvest the sun’s energy and a further 22% looking to install or upgrade their systems, according to the government’s Queensland Household Energy Survey. Of those with solar systems, 93% would would replace their panels with the same size or larger, if they were to fail.
