Researchers in Singapore claim to have set a new record for the power conversion efficiency of perovskite/organic tandem solar cells, paving the way for flexible, lightweight, low cost and ultra-thin PV cells.

TOPCon solar cells are on their way to fully compete with PERC solar products, according to recent research from Germany’s Fraunhofer ISE. Efficiency gains for the TOPCon concept, however, are necessary to help it capture more market share, as production costs remain higher than those for PERC tech. A series of cost-driven strategies to make TOPCon modules advance were outlined in the study.

The Suiso Frontier cargo vessel docked at Victoria’s Port of Hastings on Friday to take on the world’s first shipment of liquid hydrogen. The ship’s arrival is a landmark for the Japanese-Australian Hydrogen Energy Supply Chain pilot project, which sees liquefied hydrogen generated from brown coal, and an engineering milestone in itself. But while the Australian government describes the product as “clean”, experts maintain that carbon capture and storage technology has proven only to be an expensive failure.

Queensland clean energy start-up Endua’s ambitious plan to manufacture modular hydrogen-powered energy generation and storage systems has been given a financial boost with the Federal Government providing the company with almost $1 million to help it commercialise the innovative technology.

Nitricity has developed an experimental plasma reactor that uses PV electricity to produce competitively priced, environmentally clean, nitrogen fertiliser. Its onsite fertiliser production eliminates emissions from transport, and provides a viable alternative to fossil-based nitrogen fixation methods like the Haber-Bosch process.

Compiled by an international research group, the best practices were collected from all available guidelines published by national agencies, regulatory bodies, and trade associations.

In the past fortnight, Rio Tinto, Fortescue Metals, and now BHP Group have all announced they will buy electric trains to haul iron ore across Western Australia. All three companies will purchase their electric locomotives either from Progress Rail or Wabtec, both U.S based.

Transport accounts for approximately 20% of the Victoria’s emissions while also being one of the more hard to decarbonise sectors. Due to its commitment to halve its emissions by 2030, the Victorian government has announced over $7 million in grands for a number of projects seeking to commercialise real world applications in the transport sector powered by renewable hydrogen.

A Japanese group has developed a storage system with potential applications in residential storage, electric vehicles, drones and Internet-of-Things devices.

The device has a 4-in-1 design, which means it can be connected with four solar panels with a power output of up to 625 W each, through four independent connections. The output of each panel is tracked and converted individually. According to the Chinese manufacturer, the micro-inverter can ensure savings of up to 50% due to the lower number of devices and cables needed.
