To encourage industry to consider the battery mineral opportunities currently sitting in neglected heaps around the country, Geoscience Australia and its partners are developing an Atlas of Australian Mine Waste. The public database hopes to highlight the opportunity in reprocessing mining waste for new markets.

Water-from-air technology company Aqua Aerem’s Desert Bloom green hydrogen project received Major Project Status from the Northern Territory Government last year, now it has announced a partnership with Japanese energy giant Osaka Gas which not only brings the 10GW project closer to reality, but has also seen the company boost its ambitions to 20GW in light of “quickly developing demand.”

US researchers have proposed the use of hydraulically fractured oil and gas wells to store renewable energy via compressed natural gas, with the levelised cost of storage potentially coming in at US$70/MWh and US$270/MWh. They said wells could also be used to store other renewable gases such as carbon dioxide or hydrogen in the future.

Solar data company Solargis has released 10-year solar performance maps showing Australia’s massive variations in irradiance and the impacts of extreme weather patterns and events.

Western Australia’s Pinjarra alumina refinery, run by US giant Alcoa and Alumina Ltd, has been granted $8.6 million to test electric calcination, a process which could significantly reduce refineries’ footprints. The grants awarded add up to almost half of the pilot’s costs.

Sydney company CST Composites is seeking to establish Australia’s first hydrogen vessel manufacturing facility, looking to secure its position in the rapidly growing industry through a joint venture with a US-based hydrogen storage tank manufacturer.

A startup incubated at the Indian Institute of Technology Kanpur has introduced ZincGel battery tech, which could offer significant savings for owners of two-wheel electric vehicles.

A group of international scientists has investigated the potential use of radiative cooling in PV systems, in a newly published review focusing on challenges and opportunities for the passive cooling technology.

The CSIRO will invest $50 million in four new programs to drive critical breakthroughs in electric vehicle batteries and creating storage solution which could “mimic pumped hydro.”
