Energy Storage

Clean energy investor Global Sustainable Energy Opportunities expects to gain access to additional revenue streams in Australia’s National Electricity Market after completing the retrofit of a battery energy storage system at an operating solar farm in South Australia.

The New South Wales government has provided planning approvals for two new grid-scale batteries that will deliver a combined 540 MWh of energy storage capacity to support the state’s rapidly changing energy market.

Global demand for sodium-ion batteries is expected to grow to just under 70 GWh in 2033, from 10 GWh in 2025, at a compound annual growth rate (CAGR) of 27%, according to UK-based market research company IDTechEx.

Researchers at the Pacific Northwest National Laboratory in America have demonstrated the use of sugar water to improve the performance of flow batteries for grid-scale 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.
