Approaches to reduce GHG emissions from pyrometallurgical processes include: 1) increasing process efficiency, 2) replacing fossil fuels, and 3) capturing CO2 for utilization or storage. Improving process efficiency is often the easiest short-term strategy to reduce GHG emissions. It can be applied throughout the process and has the added advantage of reducing operating costs. Replacement of fossil fuels for process energy can be achieved via clean electricity usage, energy storage or clean heat integration. However, many pyrometallurgical processes require a reducing agent. In such cases, fossil fuels can be replaced by hydrogen, biofuels, fossil fuels with lower GHG intensity, or process gas. CO2 capture can be applied via post-combustion, pre-combustion, or oxy-firing technologies. Examples of each with technology readiness levels and estimated costs will be presented.
