The Northern Territory is set to install its first hydrogen energy storage system as part of a pilot being operated by the Charles Darwin University in Darwin.

West Australian natural hydrogen startup H2EX will work with Australia’s national science agency, the CSIRO, to study natural hydrogen systems in South Australia’s Eyre Peninsula, describing the research as a “pivotal first step” for the nascent industry. Natural hydrogen proponents believe projects could deliver some of the world’s cheapest hydrogen quickly and with a minimal footprint.

The novel technique consists of attaching cotton wicks immersed in the water (CWIWs) to the backside photovoltaic module. The water is supplied to cotton wicks from top to bottom by gravity which the scientists said helps the effective absorption of cotton and reduces water consumption.

Research from renowned PV scientist Martin Green and colleagues at UNSW reveals that perovskite solar cells may struggle to deal with reverse-bias caused by uneven shading or other issues likely to appear in the field. Both the reverse-bias itself and resulting build up of heat can cause several of the materials commonly used in perovskite solar cells to degrade, and these issues have received only limited attention in research published to date. Solutions, however, are at hand.

New research from the University of New South Wales (UNSW) predicts cumulative polysilicon demand of 46-87 Mt will be required to achieve 63.4 TW of PV installed by 2050.

Melbourne’s Monash University will conduct a $1.18 million study into alternative market designs which better support energy storage technologies and drive clearer investment signals.

Energy efficient homes, like those with solar panels, fetch, on average, a premium of over 17% in Australia – though that figure grows to 28.9% in Queensland and 24% in Victoria, according to a report from real estate company Domain.

Scientists in Russia have developed a new wide-band optical absorber called ‘black silicide’ which they claim is more adjusted to match AM-1.5 solar spectrum with theoretically higher photogenerated current density. It could be used for tandem operation in photovoltaic devices.

US scientist have developed a new electrolyte design for sodium-ion batteries to improve their long cycling performance. The low-solvation electrolyte was designed for high-voltage sodium-ion batteries, which retained 90% of their capacity after 300 cycles.

Researchers at Melbourne’s Deakin University have discovered a novel way to separate, store and transport large amounts of gas. The method, they say, is efficient, affordable and creates no waste – carrying huge implications for the burgeoning green hydrogen industry and for the energy transition at large.
