Distributed Storage

The inverter and battery manufacturer says its new Sella 2 factory will produce cells for its residential solar-plus-battery products as well as for other applications.

Western Australian energy storage company VSUN Energy has inked a deal with aspiring renewables developer North Harbour Clean Energy which will see the two companies collaborate on the development and installation of vanadium redox flow battery projects and vanadium electrolyte supply.

Green Gravity, a startup proposing to use old mine shafts for gravitational energy storage, has raised $1.4 million in its first formal capital raise. The company, headed up by former BHP executive Mark Swinnerton, is now finalising its concept engineering in preparation for its demonstration plant. “I think we’re going to get the ‘and’ here,” Swinnerton told pv magazine Australia, referring to the technology’s potential to provide low cost firming (and more) by using yesterday’s infrastructure to solve today’s problem.

Chinese inverter brand Sungrow has signed a 79 MW inverter and 176 MWh battery energy storage contract with Sydney-based hydrogen battery company Lavo. The contract will see Sungrow add its storage solution to 16 mid-scale solar farms in Victoria.

The New South Wales government has announced plans to use part of an estimated eight million square metres of public school roof space to install rooftop solar PV as it seeks to test the most effective ways to generate, store and export renewable energy into the state’s electricity grid.

The Australian Competition and Consumer Commission has issued a call for homeowners to urgently check their residential energy storage systems amid a national recall of some LG-branded batteries which may overheat and ignite.

Scientists in the United Arab Emirates have looked at how off-grid rooftop PV could be combined with batteries, fuel cells or reversible solid oxide cells for energy storage. The modelling assumed a typical commercial building in Los Angeles.

South Korean battery manufacturer LG Energy Solution presented its latest innovations at the Smarter E event in Munich last week. It also announced its transition from nickel-manganese-cobalt (NMC) battery chemistry to lithium iron phosphate (LFP) in its future products.

ACE Green Recycling has announced plans to build a new plant in Texas to recycle both lead-acid and lithium-ion batteries.

pv magazine summarises the products we covered at the recent Smarter E exhibition, in the first of a series of reports on all of the new releases from the annual trade fair in Munich, Germany.
