Energy Storage

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.

Pacific Energy subsidiary Contract Power Australia is set to design, construct, install and commission two batteries totalling 42 MW for Fortescue Metals Group as part of its Pilbara Energy Connect project. The storage facility is set to be the largest grid-connected battery system in Western Australia.

Scientists in the UK used the latest imaging techniques to visualize and understand the process of dendrite formation and electrolyte cracking in an all solid-state battery. With new insight into the mechanisms by which these cracks form and ultimately lead to battery failure, the results could help direct the focus of future research into solid-state battery technology.
