Assessment Of The Co2 Capture Potential From Irreplaceable Industrial Sources, Peter Psarras, Jennifer Wilcox

CO2 Summit II: Technologies and Opportunities

The industrial sector represents approximately 20% of total US CO₂ emissions.¹ These emissions can be further categorized as direct (accountable on-site, e.g., stationary combustion), indirect (assigned to electricity purchased for power) and process (CO₂ liberated as a reaction by-product). For example, steel and cement production both involve processes that directly emit CO₂ as a by-product (via the oxidation of metallurgical coke and conversion of calcium carbonate to lime, respectively). While climate change mitigation efforts have the potential to reduce direct and indirect emissions through the adoption of best practice technologies and low-carbon energy sources, process emissions …
