Energy Storage

The New South Wales government has received bids for more than 5.5 GW of wind and solar projects, along with more than 2.5 GW of long-duration storage projects, in response to its first tender to secure renewable projects to transform its coal-reliant energy system.

New Zealand’s solarZero says it aims to provide fast, sustained reserves with its virtual power plant of 10,000 household battery systems. Meridian Energy, meanwhile, has secured approval for a 100 MW battery energy storage system – the country’s largest such system to date.

Construction has begun on a 50 MW/50 MWh battery near the outback city of Broken Hill which will be equipped with advanced inverter technology designed to improve system strength in regional New South Wales and support increased levels of renewable energy generation in the area.

The Victorian government has unveiled an ambitious plan to install 100 battery energy storage systems in neighbourhoods across the state by the end of 2026 as part of a broader strategy to support the rollout of more rooftop solar PV as it targets 95% renewables by 2035.

Developer Energy Estate has signed a deal with Abergeldie Complex Infrastructure, which has designed vertical manmade caverns for hydrogen storage. Energy Estate co-founder Simon Currie says the partnership is about shoring up projects like its proposed 1.6 GW Hunter Hydrogen Network.

A 10 MW/20 MWh battery energy storage system associated with a Victorian wind farm has be commissioned by Ingeteam at the Queanbeyan substation in the Australian Capital Territory.

The New South Wales government will stage a competitive tender to secure at least 600 MW of long duration storage as well as 380 MW of firming capacity as the state looks to fill the gap created by the impending closure of the country’s biggest coal generator.

US researchers have facilitated the decoupling of power from energy design by incorporating a conducting carbon slurry in the negative electrolyte of an all-iron flow battery. In a new study, they describe the design considerations for slurry iron redox flow battery scalability.

The worst effects of the pandemic may have passed, but supply chain disruptions continue to be felt across the world. The effects of the war in Ukraine are also evident to all of us in our daily lives, from commodities to energy, food supply chains and beyond. The disruption in the battery energy storage system (BESS) supply chain is no different, writes Cormac O’Laoire, senior manager of market intelligence at Clean Energy Associates. Indeed, as the cost of raw materials such as lithium climb, battery prices are being driven materially higher, on some accounts by 20% to 30%, rendering some projects uneconomical.

French renewables developer Neoen has credited the Victorian Big Battery with almost tripling its storage revenues in the first nine months of 2022. To September, the company’s revenues totalled $547 million (USD 347.4 million), with growth in solar and wind revenues paling beside the massive surge from battery storage.
