Abstract Scope |
Aluminum reduction technology is a highly energy-intensive process, with specific energy consumption ranging from approximately 12,500 to 14,000 kWh/T, contributing to around 35% of the total production cost of aluminum. Reducing DC energy consumption in aluminum smelting is crucial for achieving significant cost savings, minimizing greenhouse gas emissions, and ensuring regulatory compliance. This paper presents an innovative approach to stub re-design, where the dimensions are optimized to maximize the contact surface area inside the hole while minimizing the area exposed to air. This breakthrough solution led Renukoot Smelter to become the first commercial smelter to operate with a 200 mm diameter stub, achieving an energy saving of 100 kWh/T. Such technological advancements in stub design reduce energy consumption and open new market opportunities for low-carbon aluminum. The findings underscore the importance of continued innovation in stub design to promote economic, environmental, and operational sustainability in the aluminum smelting industry. |
