Energy Storage

The Australian Renewable Energy Agency has announced a $100 million competitive funding round for grid scale batteries. While battery technology agnostic, the projects must be equipped with advanced inverter technology.

Researchers from Tokyo Tech have developed an alternative to hydrogen energy storage which is smaller in size and more efficient. The system utilises carbon as an energy source and demonstrates superior power density and charge-discharge efficiency of 38% over 10 cycles.

Netherlands-based renewables developer Photon Energy has reaffirmed its commitment to Australian tech company RayGen Resources’ innovative ‘solar-hydro’ technology, offloading its majority stake in the 160 MWdc Maryvale Solar Farm so it can focus its future development activities in Australia on large-scale projects featuring the solar-plus-storage technology.

An agreement with Energy Vault may see resource company BHP stack 35-tonne blocks to store wind and solar energy in the Pilbara, northern Western Australia.

Brisbane-based flow battery company Redflow has completed its single biggest installation to date, a 2 MWh storage system in California for biowaste technology firm Anaergia.

Researchers at the University of Wollongong say they have discovered a new form of graphene which will improve both anode and cathode materials in lithium-ion batteries, making them cheaper and more efficient. Collaborating with Sicona, the company has agreed to buy all the researchers’ intellectual property relating to the new material.

The device was designed by scientists in Portugal to optimise light absorption by the semiconductor and ensure an effective diffusion of redox species while offering minimal electronic and ionic transport resistance. The cell has a 25cm2 photoactive area and relies on ferrocyanide/anthraquinone redox flow chemistry and a nanostructured hematite photoelectrode.

New South Wales-based development company Greenspot has lodged a planning application for a massive 500 MW/1,000 MWh battery energy storage system to be built at the site of the shuttered coal-fired Wallerawang Power Station near Lithgow in the Central Tablelands.

The proposed measure, which will now pass to the Council of Ministers and European Parliament for debate, would further the adoption of PV, according to SolarPower Europe, especially if the commission’s proposal it be applied to public sector structures from 2027 is adopted.

Western Australian renewable energy company Plico Energy’s bold ambition to develop a grid-scale virtual power plant has received a major financial boost with Swiss investment firm SUSI Partners committing to provide capital for the rollout of 10,000 integrated solar-plus-battery systems.
