Carbon Capture, Utilisation & Storage (CCUS)

​Carbon Capture, Utilisation & Storage (CCUS) is the process of capturing CO2 from energy intensive processes before it enters atmosphere and finding a market use or transport to a storage facility (normally underground in geological caverns).

Long-term storage of CO2 in a geological formation is still relatively new as a concept but will play a huge part in the net-zero efforts in the future. However, there are possibilities to capture and utilise the CO2 in a profitable way.

Carbon capture is a key focus globally with many government incentives encouraging investment in carbon capture technology.

CO2 Fertilisation for Greenhouses

Selective Catalytic Reduction & CO Catalyst

 

  • Considers flue gas from power generation as the input
  • Ideal for CO2 fertilization for use in greenhouses to increase crop yield
  • Removal of toxic components like NOx and CO
  • CO2 concentration is equivalent to the concentration of the exhaust gas (circa 5% for natural gas operation)
  • Doesn’t increase the CO2 concentration therefore, not suitable for liquification and transportation
  • Not suitable for biogas operation due to biogas contaminants (H2S) and variability in feedstock materials
  • Consumables to consider
    • Urea
  •  

Food and Drink Grade Carbon Dioxide

Chemical Absorption

  • Considers flue gas from engine as the input
  • Ideal for low CO2 concentrations gases
  • Can achieve high purity CO2 requirements such as food or drinks standards
  • Still requires removal of toxic components (NOx & CO) with equipment similar to Selective Catalytic
  • Reduction & CO Catalyst solution being used
  • Uses solvents such amines or hot potassium carbonates to capture CO2
  • High capital and operational expenditure, however it is the only current commercially viable system to achieve high purity CO2 from hot flue gases
  • Consumables to consider:
    • Steam (for regeneration of solvent)
    • Electrical
    • Top up and consumptions of chemicals
    • Cooling water

CO2 Recovery from Biogas Upgrading

  • Considers off gas from biogas upgrading (i.e., CO2 separation) as the input
  • Ideal for high CO2 concentration input gases
  • Can achieve high purity CO2 requirements such as food or drinks standards
  • Will increase the recovery efficiency of the biogas upgrading system by separating the last part of methane in the offgas and recirculating to the inlet of the upgrading system
  • Consumables to consider:
    • Electrical
    • Absorbents for purification (minor amounts)
  •
