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.
