AGL secures planning approval for proposed Loy Yang big battery

Australia’s largest energy gen-tailer AGL says it has received approval for a 200 MW/800 MWh grid-scale battery to be developed at the site of its coal-fired Loy Yang power station in Victoria’s Latrobe Valley.

California plans 400 MW / 3200 MWh compressed air energy storage project

Hydrostor’s plant would be able to deliver 400 MW of electricity for 8 hours, and would be comparable in size to some of California’s largest fossil fuel power plants.

Queensland to build “common-user” vanadium processing plant

The Queensland government will put “at least” $10 million towards constructing a common-user facility to process vanadium from the state’s vast deposits, allowing multiple small mining operations to access the facility with the ambition of kickstarting downstream battery storage industries in the state.

The energy storage decade has arrived, says BNEF

BloombergNEF says falling battery costs and “surging” renewables penetration make energy storage a “compelling flexible resource in many power systems.” Australia is among the predicted top markets.

How to convert coal mine goaves into pumped hydro storage facilities

According to Chinese researchers, using abandoned coal mine goaves for pumped hydro facilities in combination with large scale solar and wind is not only technically feasible but can also provide an efficiency of 82.8% in yearly operation cases. They applied the model to wind and solar-rich northwestern and southwestern China.

Redox flow battery with capacity retention of 99.98% per cycle

The battery was fabricated by Chinese scientists with a low-cost electrolyte made of a derivative of TEMPO, which is a well-known electroactive aminoxyl radical used with several applications in chemistry and biochemistry. According to the researchers, the battery shows high redox potential and is crossover-free.

Off-grid green hydrogen production in Australia may already be competitive with blue

French energy giant Engie has developed a transfer function method based on a model used to assess PV plant variability. Its researchers claim that the new approach does not overestimate the levelised cost of hydrogen (LCOH) of an alkaline electrolyser powered by offgrid solar, finding that in Australia green hydrogen produced with such systems may already be cost competitive with blue hydrogen.

Long-duration thermal storage system based on silica sand

Developed by Italian dry bottom ash handling system provider Magaldi Power, the system produces green thermal energy — steam or hot air — which can be used directly in industrial plants or for the generation of electricity using steam turbines. The system consists of a blower, a fluidisation air blowing system, a fluidisation air suction system, an air filter and fan, an air pre-heater, and an integrated thermal energy storage module. Silica sands are the system’s storage media.

COP26 this! A fast, simple, Australia-tested solution to climate change

EleXsys Energy’s technology enables the controlled flow of excess energy from distributed rooftop-solar generators — think large C&I organisations and microgrid-united regional townships— to help stabilise global grids as they increasingly transition to renewables. The world could feel the positives of mass transition to solar within five years.
