Energy Storage

Flow battery technology is under the microscope with the Queensland government committing $24 million (USD 15.83 million) to further evaluate and assess the capacity of the technology to support the next stage of the state’s battery capability and help meet its renewable energy targets.

A permanent shift towards 100% renewable energy supply on Tasmania’s King Island is a step closer to realisation with the completion of a new 1.5 MW solar farm adding to the existing hybrid off-grid power system that services the island.

Construction of the 350 MW Blind Creek solar farm and large-scale battery energy storage project planned for southeast New South Wales is set to begin next year with renewables developer Octopus Australia announcing the state government has now granted planning approval.

Queensland-based investment platform Clean Energy Transfer Fund intends to circumvent lengthy lead times and major capital outlays associated with grid-scale renewables projects by deploying hundreds of sub 5 MW energy storage units throughout Australia to create coordinated battery ‘hives’ of up to 200 MWh each.

Horizon Power, Western Australia’s regional power provider, will deploy a 78 kW/220 kWh vanadium flow battery in the state’s north as it seeks to increase its understanding of how the Australian-born technology can be best utilised to support long periods of 100% renewable energy supply in regional and remote areas.

The Victorian government has announced a new $10 million (USD 6.7 million) grants program to provide bulk rebates for the installation of solar panels, solar hot water systems and heat pumps as part of plans for all new homes in the state to be 100% electric from 2024.

Energy storage specialist Eku Energy says the 200 MW/400 MWh Rangebank Battery being developed on the outskirts of Melbourne will be operational by the end of next year with early site works having now commenced on the grid-scale project.

The Alpha 150 battery, produced in the Netherlands by Adelaide-headquarted electronics manufacturer Redarc, has a lifespan of more than 5,000 cycles and a continuous discharge rating of 200 A.

A team of engineers at Melbourne’s RMIT University have developed a rechargeable ‘proton battery’, claiming the technology has the potential, with further development, to store more energy than currently available lithium-ion batteries.

Researchers in Canada have found that nearly zero-energy buildings (NZEBs) with on-site solar energy generation should not exceed an energy use intensity (EUI) of 50 kWh/m2a, which they said corresponds to a maximum of 10 floors. They also ascertained that the maximum permitted EUI by net-zero energy status is 17–28 kWh/m2a.
