ABSTRACT

The Intergovernmental Panel on Climate Change, has defined carbon capture and storage (CCS) as a process involving the separation of carbon dioxide (CO2) from industrial and energy-related sources, then transportation to a storage location providing long-term isolation from the atmosphere. Carbon capture and utilisation (CCU) is different from carbon capture and storage CCS in its final treatment of the captured CO2. The first CCU option is the direct utilisation of CO2. Bioenergy with carbon capture storage and utilisation (BECCU) processes are being developed as potential new carbon technologies. Good governance and financial incentives are also required to stimulate BECCS industrial application developments. Most of the CCS and CCU developments in the energy sector have focused on major power plants as they are ubiquitous and would provide the largest source of CO2. One of the most interesting new technological developments in CCU would be to convert CO2 to useful biofuels and chemicals.
