Vast Solar pushes ahead with ‘world-class’ solar thermal project

Australian solar thermal specialist Vast Solar has announced plans to build a 20MW concentrated solar thermal power plant with more than eight hours of energy storage near Port Augusta in South Australia after securing financial backing from the federal government.

MIT, NREL researchers develop 40%-efficient thermophotovoltaic cell for grid-scale thermal batteries

The device is described as a heat engine with no moving parts that is able to produce power from a heat source of between 1,900 to 2,400 C. This concept is known as thermal energy grid storage (TEGS) and consists of a low-cost, grid-scale storage technology that uses thermophotovoltaic cells to convert heat to electricity above 2,000 C.

Bromine-based flow batteries for renewables storage

Bromine-based flow batteries have the potential for high energy density in renewable energy storage. Their commercial adoption, however, remains challenging due to the cathode materials used for their construction. New research from China seeks to shed light on how to overcome these hurdles.

Queensland critical battery minerals project receives $5.2 million federal grant

The Commonwealth government’s Critical Minerals Accelerator Initiative has awarded a $5.2 million grant to Canberra and Brisbane-based Lava Blue, a company seeking to improve the processes of valuable minerals from vanadium pentoxide processing waste, particularly high purity alumina.

Battery fire at Salt River Project in the US

Fire crews in Chandler, Arizona, sent robots into a building at the Salt River Project where a 10 MW battery was smouldering.

Long-duration storage solution based on saltwater

Developed by Dutch start-up AquaBattery, the storage technology is claimed to independently amend power and energy capacity. The battery system utilises three storage tanks, one with fresh water, one with concentrated salt water and one with diluted salt water, and also relies on membrane stacks.
