Energy Storage

The 150 MW/300 MWh Ulinda Park battery project planned for Queensland’s Western Downs region is a step closer to a final investment decision with battery and renewable energy developer Akaysha Energy inking a hedging deal designed to manage revenue-related risks for the estimated $150 million (USD 100 million) project.

A 325 MW/2,600 MWh pumped hydro project planned for the New South Wales central west faces an indefinite delay with developer Atco announcing it will hold off on the next stage of the regulatory approvals process until the state government’s policy frameworks “are close to being able to support financial investment decisions for large-scale infrastructure.”

China’s Sinopec has switched on the world’s largest solar-to-hydrogen project in Xinjiang, while India has unveiled a new plan to incentivize green hydrogen and electrolyzer production.

New South Wales will be the test bed for the Commonwealth-funded Capacity Investment Scheme with the federal government to underwrite investment that will help deliver almost 1 GW of firmed renewable energy capacity to support the state’s rapidly changing energy market.

George Hilton, research manager at S&P Global, spoke to pv magazine at the recent Intersolar 2023 trade show about the latest energy storage trends. He said the industry needs easy-to-install products and more efficient supply chains, and noted that battery prices are highly volatile because they fluctuate in response to changes in the dynamic Chinese electric vehicle market.

Decarbon Venture, a startup cofounded by an outback-living Australian entrepreneur, has launched what it claims to be the world’s first “swappable” solar generator at half the weight and double the power rating of other products on the market.

New South Wales transmission network operator Transgrid plans to spend $16.5 billion (USD 11.22 billion) to grow the state’s power system over the next decade to ensure the “secure operation” of the grid at up to 100% instantaneous renewables.

Scientists in Belgium are exploring the potential of recycled silicon in solar modules at the end of their life cycle for reuse in low-cost, higher-energy-density storage technologies. They claim EV batteries using this silicon may allow faster recharging and travel longer distances on a single charge.

China’s Bslbatt says its new batteries have 10.24 kWh of storage capacity and a nominal voltage of 51.2 V. It measures 700 mm x 980 mm and is 100 mm thick.

Sydney company Key Energy has installed a three-phase flywheel energy storage system at a residence east of Perth, WA. The 8 kW / 32 kWh system was installed over two days in an above-ground enclosure, dramatically cutting the time needed to install the flywheel system.
