Attero Recycling, India’s largest e-waste and lithium-ion battery recycler, recently processed samples from the Jammu and Kashmir mining belt and was able to recover 200 PPM (parts per million) of lithium carbonate, which was close to the ballpark range shared by the government of India. Nitin Gupta, chief executive officer and co-founder of Attero Recycling, speaks to pv magazine about the significance of their extraction and refining methods in ensuring India’s self-reliance in critical battery-grade materials. 

OGO Energy will manufacture battery packs incorporating its battery management system and battery cells with improved longevity and heat-resistance made possible by noco-noco’s X-SEPA separators.

Enapter has unveiled its new AEM Flex 120 electrolyzer, which is designed to expedite the deployment of hydrogen projects in the industrial and refueling sectors, with a daily production capacity of approximately 53 kg.

Hitachi Energy has delivered a modular solution to electrify a 20 MW electrolyzer to produce hydrogen to heat steel before rolling, while Enapter has unveiled its AEM electrolyzers for industrial and refuelling pilot projects.

Indian scientists have produced high-purity polysilicon ingots from recycled solar cells using “spark plasma sintering” (SPS), and claim they may achieve a purity level comparable to commercially available products.

Gautam Solar claims its bussing tool reduces manual work by over 50% and doubles solar panel yield, at a fraction of the cost of an automatic machine.

Surrey-based Gas Recovery and Recycle Ltd (GR2L) will supply its ArgonØ machinery that can recycle up to 95% of argon used in the fabrication of silicon wafers for solar panels.

Despite soiling and mechanical stress, PV deployed between or close to rail tracks is not just a crazy idea, states a Bangladeshi-Australian research group. The scientists conducted a techno-economic analysis on a 128 kW demonstrator and found it may achieve a levelized cost of energy of only $0.052/kWh.

Should the industry be alarmed at the potential degradation susceptibility of tunnel oxide passivated contact (TOPCon) solar cells? Or are the problems easily addressed and more a reflection of rushed-to-market products? pv magazine contributor and consultant Götz Fischbeck reports.

In a new monthly column for pv magazine, the International Solar Energy Society (ISES) explains how much solar PV energy could be harvested from freed-up agricultural land in densely-populated countries with declining populations.
