Novel redox flow battery paves way for low-cost storage

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.

107 MW rackless, earth-mounted solar memorandum of understanding signed

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.

Putting bifacial modules to the test

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.

Terrain-following trackers evolve Australia’s uneven market

Australia’s two dominant tracker companies, Nextracker and Array Technologies, are launching terrain following products which the companies claim mitigate, sometimes even eliminate, the need for earthworks on site, opening up a host of previously unsuitable land for solar. Nextracker has just completed its first terrain-following project in Australia, with Array Technologies’ line set for delivery in the second half of 2023.

Australia and US push to ‘friendshore’ critical supply chains draws rebuke from China

“Australia’s critical minerals are at the centre of an important moment in history which could dictate the shape of the world that we will live in for the next century,” federal resources minister Madeleine King told the Rare Earth Conference in Canberra. With the strategy to grow critical mineral supply chains between Australia and the US gaining momentum, this concept of “friendshoring” was in the spotlight at All Energy 2022.

Melbourne startup converting classic cars into EVs scales bolt-in manufacturing with UK merger

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.

PV modules with longer lifetimes could slash demand for materials, says NREL

The US National Renewable Energy Laboratory (NREL) says in a new report that PV module lifetime extensions should be prioritised over closed-loop recycling to reduce demand for new materials.

Globalised supply chains saved $103 billion in solar panel production costs

A new study has calculated that the globalised PV module supply chain has saved billions for PV installers in Germany, the US and China. It also found that if strong nationalistic policies that limit the free flow of talent and capital were implemented going forward, solar panel costs would be 20-25% higher by 2030.

Cooling down solar modules by increasing space between panel rows

A US research team claims to have demonstrated that increasing the spacing of solar panels between rows improves PV system efficiency and economics by allowing airflow to cool down the modules. The method could improve a project’s LCOE by as much as 2.15% in certain climates.

Non-flammable, graphene-based lithium-ion batteries approaching stationary storage market

US-based Nanotech Energy’s graphene battery uses proprietary electrodes with a thermally stable separator, and non-flammable electrolyte that is said to be inexpensive to manufacture. The technology is said to be superior in terms of safety and competitive in terms of cell performance.
