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

Three major miners jump on electric train trend

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.

Victorian government doles out over $7 million toward green hydrogen applications in heavy transport

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.

Japanese consortium builds lithium-air battery with energy density of 500 Wh/kg

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

Micro-inverter for high-power solar panels from Hoymiles

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.
