Mining giant Fortescue Metals Group has unveiled details of a massive 5.4 GW solar PV, wind and battery energy storage project it plans to build to power its iron ore mining operations in Western Australia’s north-west.

Australian electric vehicle charging powerhouse Tritium continues to make inroads in the international market with United States President Joe Biden providing his backing for the company after it announced it will develop a new DC fast-charger manufacturing facility in the southern state of Tennessee.

Temple University researchers have found that managed sheep grazing on an acre of recovering agricultural soil with native plants may sequester 1 ton of carbon per year, which could accumulate for 12 to 15 years before reaching saturation.

Scientists in South Korea developed a porous carbon material that, when applied as a coating to the separator film in a lithium-sulfur battery, was shown to reduce an unwanted side effect and improve the battery’s performance and reliability. The coating is based on methylene blue, a type of salt commonly used in textile dying.

Indian solar company Saatvik Solar’s new facility in Haryana is equipped to make mono PERC, half-cut, multi-busbar technology, to produce high-efficiency PV modules with 530-610Wp of power output.

In 2002, the Fraunhofer ISE patented the HERIC circuit for highly efficient inverters. Since then, the institute says, it has recorded out-of-court settlements in seven patent infringement lawsuits against companies from China, Taiwan and Germany.

Spanish renewables group Gransolar says backing from international financier will “supercharge” its growth plans in Australia.

Australia’s electricity retailers have been ranked from best to worst in terms of green credentials, igniting calls for retailers to make emissions information public and transparent.

Perovskite-silicon tandem cells offer one of the surest pathways to much higher solar efficiencies, one that has moved close to commercialisation in the past few years. Much of the work getting to this stage has naturally focused on developing a viable perovskite top cell. Optimisations to the silicon layer underneath, however, will also be important to the overall device function and efficiency. Scientists in Germany examined five different silicon cell concepts similar to those in mass production today, finding that with a few optimisations these could reach efficiencies up to 30.4%.

Spanish renewable energy company Acciona is using a robot dog, instead of drones, to monitor a solar park in northern Chile. The device has a built-in thermal vision system that generates thermographic reports on the status of the different PV plant components, as it walks between the panel rows following a programmed route.
