Green Metals: Revolutionizing CO2 reduction in steel, aluminum, nickel production.

Climate change and the need for clean energy and innovation have become urgent issues in today’s world. This article highlights the innovative technologies and practices being implemented in the steel, aluminum, and nickel industries to reduce carbon dioxide (CO2) emissions and promote sustainability.

Hydro has developed HalZero technology, which converts alumina to aluminum chloride before electrolysis, emitting only oxygen and significantly reducing CO2 emissions. Rio Tinto and Alcoa have also unveiled a carbon-free aluminum smelting process that eliminates direct greenhouse gas emissions. Apple is supporting this initiative and facilitating the formation of a joint venture called Elysis to commercialize the process.

SSAB is a leader in carbon emission efficiency and aims to introduce fossil-free steel by 2026. It has partnered with Cargotec to develop SSAB Zero™, a recycled steel that emits no fossil carbon. Meanwhile, H2 Green Steel is establishing Europe’s first green steel plant in Sweden, powered by hydrogen and renewable energy sources, with the potential to reduce emissions by 95% compared to traditional steelmaking.

In the realm of nickel production, the metal is being recognized for its importance in battery technology and energy storage. Albanian Minerals is working on green nickel production and plans to present a groundbreaking achievement in spring 2024. Nickel-containing batteries offer higher energy density, cost efficiency, and environmental sustainability, making them essential for the transition to renewable energy and electric vehicles.

ArcelorMittal is also investing in green steel production, with government subsidies and aid from the European Commission. By supporting the steel industry in decarbonizing its processes, the Commission aims to promote sustainability while maintaining global competitiveness.

Overall, these innovative technologies and practices in the metals industry are driving billions of tons of CO2 reduction and paving the way for a greener and more sustainable future.
