Using Limestone to Assess the Impacts of Passivation and Ca-Silicate Formation on Lime Carbonation Efficiency for Looping Technology

Abstract Maximizing process efficiency in the lime looping process for direct air capture (DAC) is essential for reducing costs and energy demands to scale up this carbon dioxide (CO2) removal (CDR) technology. Here, we investigated two inefficiencies in the lime looping process:...

Acid Leaching for Carbon Sequestration with Prospects for Critical Metal Recovery

Abstract Reducing carbon emissions and supplying critical metals for the green energy transition are essential to limiting global warming to below 1.5 °C. Here, we propose heap leaching ultramafic material with sulfuric acid followed by sequential precipitation for nickel recover...
