Energy efficient homes, like those with solar panels, fetch, on average, a premium of over 17% in Australia – though that figure grows to 28.9% in Queensland and 24% in Victoria, according to a report from real estate company Domain.

Scientists in Russia have developed a new wide-band optical absorber called ‘black silicide’ which they claim is more adjusted to match AM-1.5 solar spectrum with theoretically higher photogenerated current density. It could be used for tandem operation in photovoltaic devices.

US scientist have developed a new electrolyte design for sodium-ion batteries to improve their long cycling performance. The low-solvation electrolyte was designed for high-voltage sodium-ion batteries, which retained 90% of their capacity after 300 cycles.

Researchers at Melbourne’s Deakin University have discovered a novel way to separate, store and transport large amounts of gas. The method, they say, is efficient, affordable and creates no waste – carrying huge implications for the burgeoning green hydrogen industry and for the energy transition at large.

New research from Ireland shows that depleted oil and gas reservoirs may be used to store hydrogen at a cost of US$1.29/kg (AU$1.9/kg). According to the researchers, underground hydrogen storage may benefit from the technological maturity of the geologic storage of natural gas and CO2, which are associated with decades of established knowledge.

University of Queensland researchers will seek to develop and test a new platform designed to help streamline the process of connecting large-scale renewable projects to the grid after landing a $498,000 grant from the Australian Renewable Energy Agency.

An international research team has developed a new way to evaluate the economic value of energy storage technologies. They went beyond pure cost assumptions to consider the benefits that such technologies could bring to energy systems.

Researchers from the Australian National University have declared a major roadblock to the electrification of the nation’s transport sector has been removed with a new study showing electric vehicles can handle the long distances required to travel to essential services in Australia’s remote and regional areas.

Interest and investment in heat pumps has surged in Europe, but in Australia the technology has struggled to find a serious foothold. Industrial heat pumps could reduce ‘hard to abate’ emissions here by 15 million tonnes per annum by 2050, according to new modelling from the Australian Alliance for Energy Productivity though. Despite the potential, dodgy technology suppliers and schemes gone awry have left a bad taste in Australia’s mouth, CEO Jarrod Leak tells pv magazine Australia.

Australia’s national science agency has reaffirmed integrated wind and solar PV remain the cheapest new-build electricity generation options but warned inflationary pressures and ongoing supply chain disruptions are likely to stall any further cost reductions for at least 12 months.
