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.

Weekend read: Five strategies for battery procurement

The worst effects of the pandemic may have passed, but supply chain disruptions continue to be felt across the world. The effects of the war in Ukraine are also evident to all of us in our daily lives, from commodities to energy, food supply chains and beyond. The disruption in the battery energy storage system (BESS) supply chain is no different, writes Cormac O’Laoire, senior manager of market intelligence at Clean Energy Associates. Indeed, as the cost of raw materials such as lithium climb, battery prices are being driven materially higher, on some accounts by 20% to 30%, rendering some projects uneconomical.

What to expect from COP27: the horns of the energy trilemma

While not one of the big five-year-cycle COPs like Paris or Glasgow, COP27 is still hugely important, write Wood Mackenzie analysts. The fallout from the conflict in Ukraine has tilted the precarious balance of the energy trilemma – sustainability; affordability; security – towards the latter. But despite this temporary setback, some progress should still be possible.

Longi launches all new back contact module, promising 22.8% efficiency

Longi has launched a series of modules featuring an all-new hybrid passivated back contact cell technology, with which it claims a maximum module efficiency of 22.8% in mass production. It will initially offer the modules in 54, 60, 66 and 72 cell formats, targeting rooftop and distributed generation applications.

Uninterrupted PV generation without storage

An Israeli scientist has proposed a way to achieve uninterrupted PV power on the moon without using energy storage. The proposal involves the installation of PV panels around a 360-degree latitudinal ring close to one of the moon’s poles. There would be no inter-array shading, and static vertical PV arrays and arrays mounted on single-axis vertical trackers could be viable mounting structures.

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.

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.

Jinko Solar reports higher sales, profit in Q3

Jinko Solar recorded a higher profit in the third quarter of 2022, as sales of its solar panels surpassed 10 GW. The Chinese PV module manufacturer said it now wants to ramp up production to keep pace with rising global demand.

Annual added PV capacity will more than quadruple to 650 GW in 2030, says IEA

The International Energy Agency (IEA) has published its “World Energy Outlook 2022” report. It expects the energy crisis triggered by Russia’s invasion of Ukraine to accelerate the global energy transition.

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.
