Alcoa Corporation (NYSE: AA) today announced a development project with the potential to significantly reduce carbon emissions in the alumina refining process, which would further enhance the company’s strong sustainability performance. throughout the aluminum value chain.
The Australian Renewable Energy Agency (ARENA) has awarded Australia’s Alcoa $ 8.8 million (AU $ 11.3 million) to test the potential use of renewable energy in a process known as recompression steam mechanics (MVR). Alcoa of Australia is currently carrying out technical and commercial studies to adapt MVR technology for refining. Electricity produced from renewable energy would power compressors to turn residual steam into steam, which would then be used to provide heat for the refinery process.
If the feasibility studies are successful, Alcoa of Australia plans to install, by the end of 2023, a three megawatt MVR module with renewable energy at the Wagerup refinery in Western Australia to test the technology on a large scale.
Already, Alcoa is the world’s lowest carbon intensity alumina producer, and the application of MVR, if successful, would be an important step forward in reducing greenhouse gas emissions. said Eugenio Azevedo, Alcoas vice president for continuous improvement. The use of lower carbon alumina in the smelting process will also reduce the overall carbon footprint of the metal, taking into account the indirect and direct emissions from bauxite mining, alumina refining and aluminum smelting and casting.
MVR technology powered by renewable energy could reduce the carbon footprint of an alumina refinery by 70%. The technology also has the potential to significantly reduce the use of water in the refining process by capturing water vapor that would otherwise be lost to the atmosphere.
Alcoa of Australia has filed provisional patent applications in Australia for the use of MVR technology in the alumina refining process. Patent applications cover a variety of MVR applications in refinery modernization and upgrade scenarios.
The development project aligns with Alcoas’ strategic priority to progress in a sustainable manner. Today, Alcoas’ global refining system has the lowest average carbon intensity in the industry, and Alcoa is the only company to supply a low carbon alumina brand, EcoSource.TMMarketed as part of the Companys SustanaTM product line, EcoSource has no more than 0.6 metric tons of carbon dioxide equivalents for every ton of foundry alumina produced, which is better than the industry’s 90 percent.
