Energy storage

Players in the electric vehicle (EV) hope the government will bring down the goods and services tax (GST) on EV batteries to 5% and lower duties on raw materials required for cell manufacturing. They also call for easy, low-cost EV finance to drive customer adoption. 

Multiple units of the 200 kWh battery system can be connected to build MWh-scale energy storage systems for use in on-grid and off-grid applications.

The Delhi-based renewable project consultant will invest $50 million in the Gujarat facility to manufacture anion exchange membrane (AEM) electrolyzers for green hydrogen generation. The project has received $1 million from Real Time Accelerator Fund as an angel investor in Greenzo.

Erisha E Mobility has formed a joint venture with Greenbox to manufacture a range of green hydrogen solutions by leveraging technologies developed by Greenbox.

Bengaluru-based Metastable Materials has developed a 100% chemical-free process for extracting metals out of scrap Li-ion batteries. It has set up an ‘Urban Mining Unit’ on the outskirts of Bengaluru, which is capable of processing up to 1,500 tonnes of dead batteries per annum. This unit will start production early next year. Shubham Vishvakarma, founder and chief of process engineering at Metastable Materials, speaks to pv magazine about the role of urban mining in meeting India’s electric mobility ambitions and the advantages of the process developed by them. 

Tdafoq Energy will use Delectrik Systems’ technology to manufacture vanadium redox flow batteries in Saudi Arabia. Construction has already started on a manufacturing facility in Saudi Arabia, which will be scaled to a GWh capacity by 2025.

Cobalt is key for boosting energy density and battery life, but it comes with caveats: expensive, scarce, and linked to unethical mining practices, wild price fluctuations, and a tenuous supply chain. In recent years, battery manufacturers and automakers have intensified efforts to reduce or eliminate cobalt in lithium-ion cathodes. But sometimes, old habits die hard, as pv magazine’s Marija Maisch explains.

Scientists in Hong Kong have designed a redox flow battery with electrolytes made of zinc and cerium. They claim to have solved the incompatibility issue posed by these two elements. The device achieved a record average Coulombic efficiency of 94% during cycling.

The Indian startup has opened a lithium battery recycling unit in Bengaluru that deploys a chemical-free process for metal extraction. The facility has the capacity to process 1,500 tonnes of dead batteries per year.

The Indian startup plans to expand its lithium battery manufacturing capacity to 1 GWh by December next year, from the currently under-construction 100 MWh.
