Utility Scale Storage

Singapore-based Sun Cable has submitted its Environmental Impact Statement to the Northern Territory Environment Protection Authority. The document reveals the full extent of the project’s enormity, specifically a 17-20 GW solar farm tied to 36-42 GWh of battery energy storage, which is set to be transmitted by subsea cables to Singapore.

Developers are moving fast to meet Singapore’s clean energy needs by establishing overseas solar-plus-storage plants, with a strong focus on facilities in neighbouring Indonesia.

Lightsource bp’s ambitious solar capacity target of 25 GW by 2025 is driving significant expansion of its Australian portfolio, including its most recent proposal of the 400 MW Gundary Solar Farm south of Goulburn, NSW.

With its promise of cheap, easy ‘god molecules’ flowing inexhaustibly from the ground, it’s no wonder natural hydrogen is piquing interest. Sometimes referred to as ‘gold’ or ‘white’ hydrogen, Avon McIntyre, executive director of HyTerra, an Australian company in the space, told pv magazine Australia natural hydrogen projects should have smaller carbon footprints than sprawling green hydrogen plays and, moreover, would be ready quicker. Enticing as it sounds, unknowns remain.

A partnership between Quantum Power Asia and Berlin-based ib vogt is proposing a 3.5 GW solar and storage facility in Riau, Indonesia, an archipelago of islands south of Singapore. The AUD$6.7 billion potential project aims to export the generated solar to the Singaporean city-state by 2032, meeting 8% of its electricity needs.

The US National Renewable Energy Laboratory’s (NREL) final report on the future of storage presents “key learnings” from a series of six in-depth studies.

Australia’s inventories of critical materials for batteries have seen major increases recently, with vanadium up 23%, lithium up 8%, rare earths up 4% and platinum group elements up 185% in the year to December 2020.

Energy Dome’s emission-free energy storage method uses carbon dioxide in a closed loop charge/discharge cycle that can store and dispatch renewable energy onto the grid over periods from four to 24 hours.

French renewable developer Neoen has signed a seven year agreement with energy giant AGL to provide 70 MW / 140 MWh of ‘virtual battery capacity’ in New South Wales.

A major Western Australian mine targeting the global vanadium battery market was this week found to be bankable, with feasibility studies confirming the project’s “strong commercial case for development,” its owner Australian Vanadium Limited said.
