Industry – Innovation Gaps – Analysis - IEA
Innovation efforts are currently under way to avoid CO 2 emissions in industry, such as through low-carbon, hydrogen-based production of steel and chemicals; using alternative, lower-carbon binding materials in cement; and employing inert anodes for primary aluminium production. Other efforts focus on CCUS, particularly in the iron and steel, chemical and cement subsectors.
