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 CO2Â 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 CO2Â fertilization for use in greenhouses to increase crop yield
- Removal of toxic components like NOx and CO
- CO2Â 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
- Â
Food and Drink Grade Carbon Dioxide
Chemical Absorption
- Considers flue gas from engine as the input
- Ideal for low CO2Â concentrations gases
- Can achieve high purity CO2Â 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 CO2Â 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., CO2Â separation) as the input
- Ideal for high CO2Â concentration input gases
- Can achieve high purity CO2Â 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)
