Developed by Italian dry bottom ash handling system provider Magaldi Power, the system produces green thermal energy — steam or hot air — which can be used directly in industrial plants or for the generation of electricity using steam turbines. The system consists of a blower, a fluidisation air blowing system, a fluidisation air suction system, an air filter and fan, an air pre-heater, and an integrated thermal energy storage module. Silica sands are the system’s storage media.

Scientists in India developed a mathematical model to predict the output of solar cells and modules in the field. The model was developed and tested using both sun simulator and actual installed modules. The scientists state that their model can be applied to a PV installation anywhere in the world, and that by taking into account module degradation over time their forecasts can be as much as 26% more accurate than existing energy yield models.

Lithium-ion batteries are a fantastic crutch for the renewable energy transition. It’s not all roses, though: Short duration limits, and potentially dangerous thermal runaway in rare circumstances, means the hunt continues for alternative electrochemical batteries. However, alternatives will largely complement lithium-ion batteries, rather than supersede them. Blake Matich looks at promising options to keep an eye on.

Developed by Spanish scientists, the proposed system design is said to be able to achieve water temperatures above 70 degrees Celsius and to cover around 85% of the annual sanitary hot water consumption of a household with six people.

Yes, Australia is blessed with an incredible solar resource, but it will be diminished and returns localised by global warming.

In the coming weeks, Western Australian mining-cum-materials recovery company Neometals will begin testing at its newly commissioned battery recycling demonstration plant in Hichenbach, Germany, the product of a joint venture with SMS Group. The Primobius facility, as it’s named, has already garnered considerable attention and is a finalist in 2022’s prestigious German Sustainability Award. “We want Primobius to be the preeminent recycler in the world,” the company’s managing director, Chris Reed, told pv magazine Australia.

A U.S. research team has sought to improve the way aluminium hydride is used for hydrogen storage. The material was nanoconfined in a framework that is claimed to be able to overcome the challenge represented by the thermodynamic limitation of hydrides in storing the clean fuel.

A team of engineers from Newcastle University have patented a thermal storage material capable of storing large amounts of renewable energy as heat over long periods. These thermal energy storage blocks are now being manufactured by MGA Thermal with ambitions to act as storage for large-scale solar systems and to repurpose coal-fired power stations.

An Indian research group has used three different chemicals instead of commonly used hydrofluoric acid to separate silicon from the cell. The technique is claimed to be able to deliver recycled silicon with a purity of up to 99.9984%.

Trackers, training and truly big-wattage panels are among the latest Trina Solar offerings. How are these various developments designed to meet the needs of the Australian utility-PV industry?
