Energy Storage

The world’s biggest solar PV and storage project has suffered a setback after a Singapore electricity retailer which had lined up to be a foundation customer for the renewable energy generated by Australia’s $26 billion Sun Cable project announced it will cease operations amid a record-breaking spike in electricity prices.

The New South Wales government at long last released its hydrogen strategy today. The wait, according to hydrogen expert Andrew Horvath, has been worthwhile. He described the strategy as clever in its approach to drawing longterm hydrogen investment into the state. “It’s a little bit different the way [NSW] looked at it,” he told pv magazine Australia, refuting the strategy’s branding as less ambitious than other states.

Green energy fund CEP.Energy is forging ahead with plans to establish itself as a renewable powerhouse, appointing Adelaide-headquartered contractor Enerven to provide engineering, procurement and construction services as it looks to accelerate its ambition to build 1.5 GW of solar and 2 GW of big battery capacity around Australia.

Queensland-based designer and manufacturer of lithium-ion battery energy storage systems RedEarth Energy Storage plans to expand its product range and increase manufacturing capacity after raising $12 million in a pre-initial public offering funding round led by Ord Minnett Private Opportunities.

The ESS battery systems have a prescribed design life of 25 years, but the battery modules, electrolyte, plumbing, and other components may well last for decades longer with proper maintenance.

The first big battery to stand alone without government support, Bouldercombe Battery Project capitalises on Genex Power’s experience gained on the road to Kidston Clean Energy Hub.

Against the backdrop of a second Victorian reverse auction for renewable energy, German-owned developer Wirsol takes up a large-scale solar project in the border city of Wodonga.

Developed by Swedish manufacturer Azelio, the system stores renewable energy in recycled aluminium and has an electrical and thermal energy output, with a total efficiency of 90 %. One unit’s storage capacity reaches 165 kWh of electrical output and on top of that thermal energy between 55-65 degrees Celsius. Its modular configuration allows the deployment of projects with a capacity of up to 100 MW.

Singapore-based VFlowTech has secured funds to scale up manufacturing of its vanadium redox flow batteries. The company currently offers three modular products that can be scaled to multi-megawatt-hour systems.

The system has dimensions of 834×417×1,766 mm and weighs 205 kg including the design panel. It achieves an electrical efficiency of 56% and can be connected with a hot water storage unit.
