Technology and R&D

Researchers at Macquarie University in Sydney have developed a new microwave technology that could advance solar-cell production by improving manufacturing processes and making them easier to recycle.

Salgenx has developed a way to produce graphene on demand from its saltwater flow battery. The tech exploits the electrochemical properties of the battery’s cathode to exfoliate graphite into individual layers of graphene. The company says it can produce graphene for less than USD 1.25 ($1.85) per gram, providing storage businesses with an additional revenue stream.

The federal government is increasing its investment in green hydrogen and low-emissions steel with $50 million in research and development funding to help progress the technologies as a new report warns that Australia must act quickly or risk being left behind in the race to become a renewable energy superpower.

The China Academy of Metrology and Science has certified Jolywood’s 26.7% efficiency rating for an n-type tunnel oxide passivated contact (TOPCon) solar cell, which the company claims is a world record. In November 2022, it announced a 26.1% efficiency rating for a similar cell.

South Australian technology company EntX has been granted a license to explore salt deposits along the western side of the Eyre Peninsula in South Australia for the purpose of hydrogen storage.

Sarcos has designed a robotic PV construction solution that delivers, detects, lifts, and places PV modules in large-scale solar plants. It has recently field tested and validated the prototype solution in a pilot project funded by the US Department of Energy.

Seeking to commercialise hydrogen technology developed by the University of Western Australia, Perth-based Hazer Group has entered into a somewhat vague agreement with Japan’s Chubu Electric Power Company and engineering firm Chiyoda Corporation.

Scientists in Italy have looked at how flywheel storage and reversible solid oxide cells could be integrated with lithium-ion batteries in minigrids powered by solar. They found that flywheels combined with batteries could be the cheapest option for power smoothing.

Stanford University researchers have created a model to assess how much compressed air storage capacity might be needed for the deep decarbonisation of power systems, while compensating for the variability of wind and solar-based power systems. They applied the model to California’s energy system and found that compressed air could be very competitive on a dollars-per-kilowatt-hour basis.

Norwegian consultancy Rystad Energy says that hydrogen pipelines will be “far better” than vessels at moving hydrogen over short- and medium-range distances in the years ahead.
