Utility Scale Storage

AGL Energy will shut down the first of four gas-fired 200 MW units at its Torrens Island ‘B’ Power Station in South Australia within three months as it looks to navigate “challenging” market conditions prompted by the ongoing penetration of renewables into the energy grid.

Global infrastructure developer AECOM has run analysis on every petroleum fuel refinery and storage & import terminal in Australia and New Zealand as a novel means of locating sites well suited to future renewable development and hydrogen industries. “Some sites that were really suited to a wide range of end uses and those were our so-called ‘unicorn sites,’” AECOM’s Craig Bearsley told pv magazine Australia.

To truly seize on the opportunity afforded by the imminent battery boom, Australia needs to look beyond its historic role as a supplier of raw materials and broaden the horizons by adding value with downstream products and manufacturing, according to a recent Future Battery Industries report. Pv magazine Australia caught up with Vincent Algar, managing director of Australian Vanadium Limited – a company operating in this promising yet thorny realm.

Lumea is planning the first big battery to be financed without any government support at Melbourne’s Deer Park Energy Hub.

Gannawarra Solar Farm, Victoria’s first large-scale solar farm integrated with a big battery, has forayed into the world of agrisolar by integrating sheep grazing on site. The sheep are reportedly loving the shade offered by the panels, which has allowed them to graze even during the hottest parts of the day, with the animals unperturbed by the solar farm’s tracking devices.

Australian renewable energy developer Maoneng has lodged plans to construct a ‘critical’ 225 MW/450 MWh utility scale battery energy storage system at Gould Creek in South Australia.

Developed by U.S. scientists, the Hydrogen Energy Storage Evaluation Tool (HESET) can assess the economic and technical characteristics of individual system components and the modelling of each hydrogen pathway. Furthermore, it can help understand how hydrogen storage can be used for various grid and end-user services.

Queensland network operator Powerlink has indicated battery storage will be a critical part of a bespoke strategy designed to solve system strength issues that have emerged as a challenge for renewable energy generation in the National Electricity Market.

Researchers from Hong Kong have applied a novel charge-reinforced, ion-selective (CRIS) membrane to a polysulfide-iodide redox flow battery they had built in 2016. The redox flow battery showed a capacity decay rate of just 0.005% per day for 1,200 cycles, and a lifetime with over 2,000 hours’ cycling, which the academics said corresponds to approximately three months.

Deakin University has received funding for two multi-million dollar facilities, one devoted to advanced battery research and the second for the development of hydrogen technology. The projects’ aims will be to overcome hydrogen’s hurdles and, for batteries, to improve existing technologies while also investigating sustainable alternatives like sodium batteries.
