1. Aluminum demand is growing rapidly due to its properties like high strength-to-weight ratio and formability.
2. Aluminum production is energy-intensive and contributes to 40% of industrial greenhouse gas emissions.
3. Several projects in the US aim to decarbonize the aluminum and other metallurgy industries by implementing low carbon technologies and reducing emissions.
Aluminum production has significantly increased in recent years, but it accounts for 40% of all industrial greenhouse gas emissions. Despite international goals for reducing emissions, they continue to rise due to expanding infrastructure development. The production process for aluminum involves refining alumina from bauxite, carbon anode production, electrolysis, casting, and secondary metal treatment. These processes contribute to direct and indirect emissions, making aluminum production a significant contributor to carbon footprints.
To address this issue, a focus on decarbonizing the aluminum and other metallurgy industries is crucial. The US Department of Energy announced funding for 33 projects across more than 20 states to support the decarbonization of energy-intensive industries, reduce industrial GHG emissions, and strengthen manufacturing competitiveness. These projects include initiatives like building a new aluminum smelter with high energy efficiency, deploying zero carbon aluminum casting plants, upgrading aluminum recycling facilities, and expanding copper recycling capabilities.
These projects aim to reduce carbon emissions, improve process efficiency, and enhance recycling practices to achieve a low carbon future. By implementing emerging low carbon technologies in the metallurgy industry, governments can work towards meeting climate goals and advancing towards carbon neutrality and decarbonization.
