SINGAPORE, May 14, 2024 /PRNewswire/ -- Addressing the urgent challenge posed by escalating carbon dioxide (CO2) emissions and their impact on climate change, researchers from the National University of Singapore (NUS) have developed a novel technique that significantly advances the conversion of waste carbon dioxide (CO2) into value-added chemicals and fuels.

Key Points: 
  • Carbon capture, utilisation and storage is a fundamental process to a sustainable future, relying on a suite of technologies among which the electrochemical reduction of CO2 is vital.
  • Furthermore, the presence of oxygen impurities in flue gas results in undesired side reactions, which significantly reduces the efficiency of the CO2 reduction process.
  • Utilising this approach, they designed a nickel catalyst boasting exceptional performance for CO2 reduction, achieving an impressive efficiency rate exceeding 99 percent.
  • This versatility offers a broad platform for converting waste CO2 into a diverse range of chemicals, underscoring the technique's adaptability to different industrial needs.

The sulfate was generated during bench-scale testing of its hydrometallurgical flowsheet design in partnership with SGS Canada Inc., at their Lakefield, Ontario facility.

Key Points: 
  • The sulfate was generated during bench-scale testing of its hydrometallurgical flowsheet design in partnership with SGS Canada Inc., at their Lakefield, Ontario facility.
  • Undertaken on samples of nickel-cobalt-copper matte produced by TMC in 2021, the Extractive Metallurgy team at SGS tested TMC’s efficient flowsheet to process high-grade nickel matte directly to nickel sulfate without making nickel metal, while producing fertilizer byproducts instead of solid waste or tailings.
  • Following the successful nickel sulfate production, SGS continues testing to produce what TMC believes will be the world’s first cobalt sulfate from polymetallic nodules.
  • This work was executed in close collaboration with SGS and other industry leaders to demonstrate the ability to refine nodules to high value products.
