Energy Storage

Australia’s national science agency has identified a potential $3.1 billion industry that is there for the taking with the increasing penetration of renewables in grids nationwide sparking substantial growth in the battery energy storage sector.

While Treasurer Josh Frydenberg is putting the finishing touches on the Federal Budget, the Northern Territory Government has already rolled out its 2021-22 Budget and solar PV and battery storage are among its spending priorities with an extra $4.8 million invested in existing renewable energy schemes.

A clean energy investment firm based in Canada but already with a growing portfolio in Australia has set out an expansion plan in excess of $2 billion and 1.3 GW for the creation of a Renewable Energy Hub of South Australia, including at least three massive solar projects, two of which would supply South Australia’s green hydrogen ambitions.

Scientists investigating the aging mechanisms affecting today’s lithium-ion batteries observed that the loss of lithium over time is one of the main causes of performance loss. With this in mind, they developed and tested a “relithiation” process that promises to eliminate much of the cost and complexity from recycling battery components and materials.

Silicon Valley-based start-up Gridtential has secured US$12 million (AU$15.5m) in funds to develop what it calls the world’s first factory-ready, single-block, 24V, deep-cycle lead battery. The product is claimed to be ideal for personal mobility vehicles and renewable energy storage in homes and offices.

Recommendations by the NSW Independent Pricing and Regulatory Tribunal will see payback times for solar systems extended, but also favour battery uptake.

An Australian innovation, the unassuming-looking CQSola power controller has under-the-hood smarts that could significantly cut the cost of hydrogen produced using solar energy.

Owners and operators of energy storage systems, as well as investors, need transparent ways to evaluate battery performance. They need certainty that the selected batteries for their ESS projects will perform reliably, have predictable life expectancies, and meet projected revenue and contractual obligations over their lifetimes. The economic viability of entire projects depend on this confidence, writes Michael Kleinberg of DNV.

The Chinese manufacturer will begin selling its new products in Australia and Europe. The hybrid inverter has an efficiency of up to 98.4% and the lithium iron phosphate battery features a storage capacity between 9.6 kWh and 102.4 kWh, depending on the number of modules.

The National Energy Administration has ordered grid companies to supply enough network connection points for all the solar and wind projects registered in 2019 and 2020, and said variable renewables should be supplying 11% of the nation’s electricity by the end of the year.
