Researchers in Australia are investigating a novel approach to carbon sequestration in mining waste by utilizing concentrated solar heat to accelerate the process. By activating serpentine in the waste material, carbon can be captured and stored efficiently, mimicking the natural process of silicate weathering. This advancement in technology aims to enhance the kinetics and efficiency of carbon sequestration, with the potential to scale up the process for industrial applications. The study conducted at the University of Adelaide focuses on optimizing the physical-chemical characteristics of the activated materials, leading to improved surface area and porosity. The research highlights the economic viability of using solar heat compared to traditional fossil fuel-based methods for carbon capture in mineral deposits. The Mount Keith Nickel mine in Western Australia emerges as a promising site due to its capacity for mineral carbonation and high CO2 absorption potential. The mine's nickel waste has shown to absorb more CO2 than it produces, positioning it as a carbon sink over a long period. In addition to solar heat, the researchers propose utilizing green hydrogen combustion for continuous operation, demonstrating a sustainable approach to reduce carbon emissions. The potential integration of green hydrogen technology further signifies a commitment to environmental stewardship in the mining sector. Overall, this innovative solution presents a positive outlook on harnessing renewable energy sources to address carbon sequestration challenges in the mining industry.
