On National Energy Conservation Day, Vedanta Aluminium unveiled a groundbreaking advancement in the lining design of the 'pots' at its aluminium smelters. 

The patented 'Vedanta Lining Design' showcases a remarkable energy-efficient technique, promising increased efficiency and prolonged lifespan for smelting pots, with a significant reduction in energy consumption by 200 to 250 KWh per tonne of aluminium produced.

The Ministry of Power's Bureau of Energy Efficiency (BEE) has recognized this innovation at the National Energy Efficiency Innovation Awards (NEEIA) 2023. The President of India, Droupadi Murmu, presided over the ceremony, offering a prestigious accolade to Vedanta Aluminium's commitment to championing energy efficiency and conservation.

This acknowledgment shows the company's dedication to transformative innovations in the global aluminium industry, aligning closely with the UN Sustainable Development Goals of Industry, Innovation & Infrastructure (SDG9), Responsible Consumption and Production (SDG12), and Climate Action (SDG13).

The 'Vedanta Lining Design' is the result of extensive numerical computational modeling, simulating electrical and thermal behaviors within smelting pots. Following a successful year-long trial, the design is set to be implemented across Vedanta Aluminium's smelters, including the world-renowned Vedanta Jharsuguda in Odisha and BALCO in Korba, Chhattisgarh. The implementation is projected to curtail GHG emissions by up to 3.86 lakh tCO2e per annum, particularly at the Jharsuguda smelter.

Vedanta Aluminium, emphasizing transparency, has also released its second annual Climate Action Report, following the Task Force on Climate-Related Financial Disclosures (TCFD) framework. This report outlines the company's comprehensive approach to sustainability targets in the short, medium, and long term. The detailed report is accessible on the company’s website. 

Commenting on the company's commitment to energy conservation, John Slaven, CEO of Vedanta Aluminium, stated, "At Vedanta Aluminium, climate action is a key strategic pillar and business imperative. Our focus on energy management and conservation is setting new benchmarks in responsible production across the industry value chain. We are optimizing energy consumption and transitioning to sustainable energy alternatives to lead the charge in the aluminium industry."

As part of its innovative initiatives, Vedanta Aluminium has integrated graphitization into its pot lining design, enhancing the properties of cathodes crucial to the smelting process. This integration, nearing completion in both smelter locations, ensures enhanced electrical conductivity, contributing to increased energy efficiency and sustainable operations.
