Industrial processes like the manufacture of steel, cement, fertilizers and petrochemicals, especially plastics, account for one-third of our global energy use. The world now produces annually about 4.5 billion tons of cement, 1.8 billion tons of steel, nearly 400 million tons of plastics, and 180 million tons of ammonia. Their manufacture requires high temperatures, which is often the case, the heat comes from burning fossil fuels. What is the path to decarbonize industrial processes? In this episode we talk to two researchers from the Payne Institute for Public Policy at the Colorado School of Mines about their recent work on “green steel and carbon sequestration.” Let’s welcome Anna Littlefield and Edikan Udofia.
