Indigenous communities have some of the most unreliable, expensive power in Australia, with a recent study finding almost three quarters of households in remote Northern Territory communities lost power more than 10 times, often for significant periods on “dangerously” hot days. Alarmingly, regulations have until now completely blocked communities in public housing from connecting rooftop solar because they use a prepaid meter system.

In an unconventional bid to attract large-scale renewable developments, the Queensland government has organised for usually highly confidential solar and wind monitoring data to be made public for the first time through Fulcrum 3D’s technology platforms.

The device was designed by scientists in Portugal to optimise light absorption by the semiconductor and ensure an effective diffusion of redox species while offering minimal electronic and ionic transport resistance. The cell has a 25cm2 photoactive area and relies on ferrocyanide/anthraquinone redox flow chemistry and a nanostructured hematite photoelectrode.

The AI-enabled robot is claimed to ensure faster and more efficient deployment of solar modules in utility scale projects.

Green hydrogen can play a vital role in decarbonising the economy and enabling countries to reach net-zero emissions. The economics of producing green hydrogen from electrolysis are maturing as developers scramble to meet expected future demand. Everoze partner Nicolas Chouleur and Neoen hydrogen expert Sacha Lepoutre discuss a case study that shows how stacking different revenue streams could improve the economics of renewable energy projects.

Norway-based REC Group’s REConstruct Initiative is helping communities hit hard by the Black Summer Bushfires of 2019-2020 by donating solar systems to help bring savings on electricity bills and independence to vulnerable areas cut off from the grid during the catastrophic fires.

Urban transportation is key to modern civilization. It has enabled humans to travel long distances and is one of the building blocks of industry and leisure. But it has come at a cost. In the first quarter of 2022, pv magazine’s UP Initiative will focus on the rise of e-mobility. We will examine urban transportation and the role electric vehicles, trains, and two- and three-wheelers can play in greening the electricity grid. In addition to technological innovation, we will also investigate market projections, the policies and infrastructure required, and the role solar and storage will play in taking this nascent industry full throttle.

Building on our previous Chart of the week in October, where we reviewed the first couple of weeks of 5-minute settlement, we wanted to revisit this topic. Now two months in, we take another look and see how well the fastest responding assets in the NEM are capturing the best prices in the 5-minute market.

The latest estimates of electricity generation costs in Australia have confirmed solar and wind continue to be the cheapest sources of new-build electricity generation, even when factoring in additional integration costs such as storage and new transmission infrastructure.

New South Wales-based development company Greenspot has lodged a planning application for a massive 500 MW/1,000 MWh battery energy storage system to be built at the site of the shuttered coal-fired Wallerawang Power Station near Lithgow in the Central Tablelands.
