Recycling rare-earth elements from dead lithium batteries
American Resources Corporation is developing a process to separate pure rare earth metals from lithium-ion batteries used in electric vehicles or power plants based on renewable energy. The technique is described as a two-zone ligand-assisted displacement chromatography (LAD) that is able to produce metals with high yields and purity of over 99%.
India ranked third most attractive country for solar investment
India ranks behind the United States and China in IHS Markit’s latest rankings of most attractive solar markets.
The long read: The ‘other side’ of batteries
Graphite’s pivotal role in electric-vehicle battery technology is coming under increasing scrutiny. Graphite is almost exclusively produced in China, and while the processing of the mineral poses serious environmental issues, the alternatives appear costly. Ian Morse looks at what’s next for critical graphite supplies.
Virescent Infrastructure acquires 76 MW of operating solar assets in India
US investor KKR-backed Virescent Infrastructure has acquired Singapore-based Sindicatum Group’s operating solar assets in three Indian states. The acquired PV projects benefit from long-term power purchase agreements with government counterparties.
Maharashtra discom tenders for purchase of 500 MW solar power
Solar power generators have until June 4 to bid for supplying the power from their proposed or existing PV projects under a 25-year PPA.
Rising Sun Energy seeking EPC partners for its 190 MW Rajasthan solar project

Indian firm designs solar sculpture to produce 300 MWh of electricity annually
Called Solar Mountain, the permanent installation should be built in Nevada with modular design elements of recycled wood and other environmentally friendly materials.
Developing climate-resilient decentralized solar solutions
A new report states decentralized solar installations in climate-vulnerable regions of Assam, Jharkhand, and Rajasthan lacked design to deal with future climate risks. The report authors, based on their study, outline considerations for policymakers, implementing agencies, vendors, and funding agencies to build resilient structures.
IREDA to launch call for applications under the production-linked solar incentive scheme soon
Indian Renewable Energy Development Agency Ltd (IREDA), the implementing agency for the Production Linked Incentive (PLI) Scheme, would soon issue the selection document for solar manufacturers who wish to apply for state cash to set up production lines in India.
Lithium saturation to make old batteries new
Scientists investigating the aging mechanisms affecting today’s lithium-ion batteries observed that the loss of lithium over time is one of the main causes of performance loss. With this in mind, they developed and tested a “relithiation” process that promises to eliminate much of the cost and complexity from recycling battery components and materials.
