Carbon Capture and Utilisation in the green economy

Using CO2 to manufacture fuel, chemicals and materials as part of a low carbon economy.

Abstract

Carbon capture and storage is seen world-wide as a technology in the global portfolio of mitigation options that can contribute to cost-effective mitigation. However, the past years have shown that significant drawbacks are associated with CCS options that capture CO2 from an industrial point source or power plant and store it in a geological reservoir. Geological storage is confronted with the possibility of leakage, long-term liability issues, problems with public acceptance of onshore storage locations and limited cost-effective storage capacity in some essential regions. This paper gives a brief technical and economic assessment of a partial alternative to geological storage: carbon capture and utilisation (CCU). For this paper CCU is defined as a process whereby the CO2 molecule ends up in a new molecule. The paper discusses use of CO2 for the chemical industry, for mineral carbonation and to grow microalgae.
Although these options are for the most part in the R&D phase, they offer potential for value-added applications of carbon dioxide captured from an industrial installation or power plant. In addition, the paper places them in a UK policy context and makes
several internationally and UK-relevant recommendations, while exploring their
potential contribution to a green economy.
