Technology and R&D

NREL and Berkeley Lab have proposed efficiency and stability best practices for solar water-splitting to make hydrogen, while a team of researchers from Malaysia and Pakistan have revealed their findings on the feasibility of hydrogen-based incineration.

US researchers have facilitated the decoupling of power from energy design by incorporating a conducting carbon slurry in the negative electrolyte of an all-iron flow battery. In a new study, they describe the design considerations for slurry iron redox flow battery scalability.

Western Australia’s largest virtual power plant, the government-support Project Symphony, is live. The project is particularly noteworthy for its introduction of new markets to reward different services and its use of Dynamic Operating Envelopes.

Longi has launched a series of modules featuring an all-new hybrid passivated back contact cell technology, with which it claims a maximum module efficiency of 22.8% in mass production. It will initially offer the modules in 54, 60, 66 and 72 cell formats, targeting rooftop and distributed generation applications.

US-based Erthos announced a 14 MW portfolio of earth-mount solar PV projects under contract along with a memorandum of understanding for a 107 MW project.

An Israeli scientist has proposed a way to achieve uninterrupted PV power on the moon without using energy storage. The proposal involves the installation of PV panels around a 360-degree latitudinal ring close to one of the moon’s poles. There would be no inter-array shading, and static vertical PV arrays and arrays mounted on single-axis vertical trackers could be viable mounting structures.

US scientists recently put different bifacial solar cells and modules through a series of tests at elevated temperature, humidity, voltage and mechanical stress levels. The tests revealed a range of light-induced and potential-induced degradation mechanisms that modules will likely suffer in the field.

Bolt-in electric vehicle kits in Australia have just got a leg up, with Melbourne startup Jaunt Motors joining forces with UK company Zero EV to operate a new, larger scale business to have production facilities and operations across Australia, the UK and, “very soon,” the US.

Qingdao University researchers have synthesised high-performance titanium dioxide-based anode materials with excellent cycling stability, while German scientists have used operando techniques to observe how solvated sodium ions embed themselves in electrodes.

A consortium of Singaporean universities and companies will study the feasibility of integrating a hybrid floating solar project with ocean, tidal, and wind capacity. If successful, the parties plan to deploy a pilot system with at least 100 MW of renewables capacity.
