Energy Storage

UK-based developer Renewable Energy Systems Group is planning to build a 250 MW/600 MWh battery energy storage system in the New South Wales Hunter region that is says would provide critical grid services and support Australia’s renewable energy transition.

UK scientists have discovered that second-life batteries could provide a lower levelised cost of electricity (LCOE) than conventional batteries in school buildings equipped with PV in East African schools. They said the cheapest system configuration uses either 7.5 kW or 10 kW of solar with 20 kWh of storage.

Sixteen projects representing more than 4.3 GW of large-scale generation and long-duration storage have been shortlisted as part of the first of a rolling schedule of competitive tenders designed to ensure New South Wales’ successful transition from coal-fired power generation to a renewables-based energy system.

Scientists in Austria have developed a long-term energy storage system that uses regenerative braking to adjust the descent speed of sand in mine shafts and generate electricity.

The Queensland government will invest $75 million (USD 53 million) to expand a critical minerals demonstration facility in Townsville – a project it claims will be an Australian first. The facility, slated for operations in 2025, is part of a growing push in Australia to develop battery materials industries beyond simply mining.

Esysunhome (ESYSH), a new energy storage company in China, has developed a 5.12 kWh lithium iron phosphate (LFP) battery system with a 7.9 kW inverter. It says six modules can be combined for up to 30.72 kWh of energy storage capacity.

South Australia has become the first jurisdiction in Australia to approve network connection of vehicle-to-grid technology in a residential setting, providing electric vehicle owners with the opportunity to send energy stored in their car’s on-board battery back into their own homes or the electricity grid.

With global demand for new energy storage soaring and nations and companies racing to secure battery metals supply chains, a series of major investments in Australia and Australian lithium mining companies is expected to accelerate the nation’s transformation into a critical minerals powerhouse.

Queensland-based ReNu Energy will acquire up to a 20% stake in fellow Brisbane company, startup Vaulta, which has developed battery casings designed for reuse and recycling. Vaulta will use the eventual $1 million (USD 700,000) investment from ReNu to scale its manufacturing capability and expand domestic and offshore sales.

Geelong is set to become home to a $300 million (USD 210 million) lithium-ion battery gigafactory. Recharge Industries, part of a portfolio from US fund Scale Facilitation, is aiming to start construction by the end of the year, targeting 2 GWh of production annually in 2024 and 6 GWh by 2026. The company is reportedly aiming to produce batteries without using Chinese materials, and appears to be part of a deepening supply chain play between Australia and the US.
