The Greens are proposing to electrify an entire Australian town and a suburb in a major city, including providing electric vehicles for households, the party’s leader Adam Bandt has revealed. The proposed pilot, which would be enabled by a $235 million fund, was inspired by Australian Saul Griffith’s ‘electrify everything’ campaign.

Renac Power’s new plug-and-play battery has a storage capacity of 3.74 kWh, but it can be enhanced in series with up to five batteries to 18.7 kWh. It has a nominal voltage of 96 V and a voltage range of 81 V to 108 V.

Enray Solutions has developed an autonomous, water-free cleaning robot for ground-mount solar installations that draws its power from an on-board PV panel and battery. The robot is designed to withstand the harsh environmental conditions of all kinds of terrain.

Advanced Ionics has developed an electrolyser that runs at temperatures below 650 C. It is reportedly able to produce hydrogen for US$0.85/kg (AU$1.2/kg) or less. CEO Chad Mason recently spoke with pv magazine to provide a closer look at the water vapour electrolysis tech.

Switzerland’s Energy Vault will support Indian state-run power producer NTPC by deploying its gravity-based energy storage technology and software solutions.

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.

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 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.

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.

France’s environmental agency Ademe has released a set of new guidelines that clearly define “agrivoltaics.”
