Energy Storage

Scientists in India fabricated a redox flow battery based on zinc and iron that showed strong storage characteristics and no signs of degradation over 30 charge-discharge cycles. The battery also showed no signs of dendrite formation, overcoming one of the key hurdles for redox-flow batteries based on these low-cost, abundant materials.

South Australia is a global hero for its demonstration of a rapid transition to renewable generation. But as renewables supplied more than 60% of the state’s electricity, and pushed out coal and even gas-fired generation, cracks appeared in the system strength and inertia required to keep the grid reliably running. ElectraNet has deployed old, clean-running technology — synchronous condensers — to smooth the gaps.

PV electricity generation is a natural choice for Australia’s remote Kimberley region. State-owned energy provider Horizon Power has deployed WA Recovery Plan funds to make the most of the interplay between sun and shade and put clean energy behind the Derby community’s aspirations.

Processing nightmare, or product opportunity? Impending five-minute settlement comes at a difficult time for energy retailers. Software from across the ditch could help highlight the benefits and opportunities of more solar and a forecast uptick in battery energy storage.

With manufacturing ramping up year by year and policies already looking to get ahead of the large volumes of end-of-life products, the landscape for lithium-ion battery recycling is rapidly changing. pv magazine recently spoke with Mari Lundström, associate professor of chemical and metallurgical engineering at Aalto University, to find out what is needed on the research side for the effective recycling of batteries.

Japan’s biggest oil refiner Eneos and French renewables developer Neoen have announced they will undertake a joint study looking at the potential development of an international supply chain for an affordable and stable supply of green hydrogen produced from renewable energy in South Australia.

The Australian arm of global fund manager Octopus Group has expanded its renewable energy portfolio, teaming with the Clean Energy Finance Corporation to purchase the rights to develop two proposed utility scale solar-storage hybrid power plants in Victoria’s Gippsland region.

Work on the Jabiru Hybrid Renewable Project – featuring solar PV and battery energy storage – has achieved another milestone with project developer Energy Developments Limited confirming clearing works for the power plant being built in the World Heritage-listed Kakadu National Park are now complete.

Renewable energy developer Elliott Green Power is pushing ahead with expansion plans while continuing to seek a buyer for its Australian solar PV assets, announcing it has received approval to develop a utility scale battery alongside the 75 MW Susan River Solar Farm in regional Queensland.

Less than a week after fire broke out at the Victoria Big Battery in Geelong, Australian renewable energy developer Maoneng has given lithium iron phosphate batteries the tick of approval, declaring it will use the technology at its utility scale battery energy storage system planned for Victoria’s Mornington Peninsula.
