New Zealand and Germany have partnered up to provide NZ$2 million (AU$1.8m) each to three green hydrogen research projects, including one to develop more efficient anion exchange membrane electrolysers which promise to be cheaper and more sustainable to manufacture.

Combining satellite images of Australian rooftops with those of real-time cloud cover to create accurate forecasts of distributed solar output for suburbs and perhaps even whole regions and states is the focus of a new Australian startup, Solstice AI. “We’re kind of at a point now where there’s so much solar that it’s causing all these issues but, if we can forecast it, many of these issues can be alleviated or managed much better,” the company’s cofounder and CEO, Julian de Hoog, tellspv magazine Australia.

Indian researchers have developed a new hybrid system featuring a conventional rooftop PV system, a solar tree, two gravity power modules for building (GPMBs), and a vanadium redox flow battery (VRFB), with power exclusively provided by the two solar installations.

Nine partners from seven European countries are involved in the €3.6 million (AU$5.25 million) “Reveal” research project, which says buildings could be heated in the future by storing energy from PV, wind and water in aluminium.

Hype and hope for solid-state batteries (SSBs) continues to grow as industries from automotive to storage bet big on the technology. Leading battery manufacturers and a roll call of start-ups are jostling to get from lab to fab. The reality of SSBs is in question though. As Marija Maisch reports, the window of opportunity for the decades-old technology to make the next big step toward commercialisation is now.

In a study that began in 2016, scientists in the United States purchased 834 PV modules, representing seven manufacturers and 13 module types, and installed them in various climate conditions to observe their performance over time. The results show that, while plenty of opportunities still exist to extend module lifetimes and reduce performance loss in the field, reductions in the manufacturing cost of PV have not come with an increase in their degradation rate.

Researchers at the University of Cambridge have examined one of the fastest-charging anode materials by using a low-cost, lab-based optical microscopy technique. Their findings showed that particle fracture, which can reduce the storage capacity of a battery, is more common with higher rates of delithiation and in longer particles.

The Australian Energy Regulator has approved more than $300 million of funding to support early works on the HumeLink project which is expected to boost overall transmission capacity in New South Wales, paving the way for gigawatts of new wind, solar PV and storage projects.

Researchers in China have reported a colourisation strategy for solar based on photonic glass. They created solar panels that took on blue, green, and purple hues, while only dropping the efficiency of power generation from 22.6% to 21.5%.

With headlines dominated by spiking electricity prices and energy security, the demand for off grid solutions in Australia is booming. “It’s starting to make financial sense, that’s significant,” Matt Miller, the marketing manager for Victorian company Commodore tells pv magazine Australia.
