Norsk Hydro Partners with Rio Tinto for Innovative Carbon Capture in Aluminium Production

Norsk Hydro and Rio Tinto Forge Partnership for Carbon Capture in Aluminium Production

Norsk Hydro and Rio Tinto announce a significant partnership aimed at advancing carbon capture technologies within the aluminium production sector. This collaboration focuses specifically on reducing CO2 emissions generated during the electrolysis smelting process, a key area of concern for both companies as they strive to meet ambitious climate targets. The agreement includes a comprehensive sharing of information, research results, and associated costs, facilitating a robust exploration of innovative solutions. Together, they plan to invest nearly $45 million over the next five years, primarily targeting research activities at Rio Tinto's European facilities and Hydro's sites in Norway.

Central to this partnership is the recognition that anode consumption during electrolysis is responsible for approximately 75% of a smelter's direct CO2 emissions. This stark statistic underscores the urgent need for advanced carbon capture technologies. Both companies have been independently researching these technologies, with Hydro developing its HalZero technology and Rio Tinto participating in the ELYSIS joint venture aimed at creating carbon-free aluminium. Their joint efforts are expected to enhance the pace of innovation, enabling the development of effective solutions that can significantly decrease carbon footprints in the aluminium production process.

As they embark on this collaborative journey, Hydro's President and CEO Eivind Kallevik emphasizes the critical need for decarbonization in the industry. The partnership seeks to tackle the technical challenges inherent in capturing carbon from aluminium smelter flue gas, which contains around 1% CO2. While current carbon capture technologies exist, they require substantial advancements to transition from laboratory tests to commercial implementation. By pooling resources and expertise, Norsk Hydro and Rio Tinto aim to accelerate the development and deployment of these technologies, ultimately contributing to a more sustainable future for aluminium production.

In addition to their focus on carbon capture, both companies are committed to innovative smelting solutions that align with their sustainability goals. The partnership reflects a broader industry trend towards collaboration in research and development, as companies recognize the complexities of achieving net-zero emissions by 2050. This initiative not only positions Hydro and Rio Tinto as leaders in environmental responsibility but also sets a precedent for others in the aluminium sector.

The combined efforts of Hydro and Rio Tinto represent a proactive approach to tackling one of the industry's most pressing challenges. Their commitment to developing carbon capture technologies could serve as a vital step in mitigating greenhouse gas emissions, aligning with global sustainability efforts and the urgent call for industries to transition to greener practices.
