How to minimize grid purchases in storage-integrated PV systems
Scientists in Poland have developed a machine-learning method to help solar+storage system owners manage battery charging and discharging, so they can avoid buying power from the grid.
Italy has 170 MW/267 MWh of distributed storage capacity
The country added around 90 MW/100 MWh of new, small-sized storage capacity over the past 18 months. Most of the batteries are in Lombardy, whose administration offers rebates.
Dual-ion battery prototype promises safe and cost-competive energy storage
Scientists have fabricated a working battery using a new type of dual-ion chemistry. The design avoids many of the rare or expensive materials found in today’s lithium-ion batteries, and also comes with an inherently lower risk of fire. The battery showed promising performance, and its creators say they have identified several areas where performance could potentially be improved.
Giant battery to unlock Australian renewables
The Australian state of Victoria is on track to host one of the world’s largest lithium-ion batteries. The 300 MW/450 MWh Victoria Big Battery will be constructed on the outskirts of Geelong.
‘Disrupters’ tip Australia to host world’s biggest VPP in 2021
As Australia’s home battery market begins to catch up to its installed residential solar capacity, the opportunity for large-scale virtual power plants is verging on reality. Indeed, Solar Service Group’s new Solar + Battery Members’ Plan could see Australia host the world’s largest virtual power plant next year.
Australia’s largest chicken farm switches on solar+storage system
Australia’s largest free-range chicken farm switched on a big solar+storage system this week, with 1.4 MW of rooftop solar and 2.28 MWh of energy storage, via five Tesla lithium-ion batteries.
South Australia awards 10-year PPA to 260 MW of PV, 100 MW battery
Construction of the state’s biggest PV array and its fifth “big battery” will create 810 jobs. The state government forecasts US$8.96 million of energy savings over the course of the decade-long contract.
Major economies should divert fossil fuel Covid-recovery cash to clean energy before it’s too late
A report by Finnish company Wärtsilä has estimated the potential impact if every dollar committed to a non-renewables energy sector recovery was instead funneled to clean power.
Engie EPS deploys ‘power-to-power’ hydrogen-based storage solution
Engie’s storage subsidiary has unveiled its hydrogen-based energy storage system, built with its proprietary technology, in Agkistro, Greece.
Organic redox flow battery with PEDOT electrodes
Swedish scientists have developed a redox flow battery with polymer electrodes, based on a special conductive polymer known as PEDOT. The battery features a water-based electrolyte based on a solution of redox quinone molecules, which can be extracted from forest-based materials.
