The industrial sector is looking for alternative carbon sources able to replace oil and gas in their production processes. Carbon dioxide (CO₂) is considered a non-toxic, and abundant C1 feedstock. The term CO₂ utilisation describes technologies that use carbon dioxide to provide a service or a product with economic value. This chapter will provide an overview of key potential uses, technological challenges and bottlenecks of CO₂ utilisation. Given the broad range of potential CO₂ uses, an overview of key uses is provided categorised according to the fate of CO₂ in the product: CO₂ into fuels/chemicals; CO₂ into agglomerates/materials for construction, and CO₂ in the subsurface to extract energy sources.
