The Technology
Carbon Capture
Humber Zero will be one of the world’s largest carbon capture projects. The first phase of the project will see the deployment of post-combustion capture technology, which aims to capture at least 95% of the carbon dioxide (CO2) produced from two of the VPI Immingham Combined Heat and Power Plant gas turbines and as part of the Phillips 66 Limited’s Humber Refinery fluid catalytic cracking (FCC) process, which processes renewable and conventional feedstocks.
We will use Shell’s CANSOLV CO₂ Capture System to capture the flue gas that is normally emitted from the chimney stack and remove the majority of carbon dioxide using an amine solvent. The captured CO2 will then be compressed into a fluid state, which will allow it to be transported to the Viking gas fields in the North Sea.
The remaining flue gas is then released into the atmosphere while the solvent is returned to the beginning of the process to capture more CO2.
Transportation and Storage
Humber Zero is working closely with Viking CCS (led by Harbour Energy together with non-operated partner bp), as a potential initial emitter to the Viking CCS Cluster, which aims to transport and store up to 10 million tonnes of UK emissions per year by 2030.
VPI Immingham and the Phillips 66 Humber Refinery are uniquely positioned in relation to the Viking CCS pipeline.
Captured CO2 will be transported from Immingham to Theddlethorpe via a new 55km onshore underground pipeline. From Theddlethorpe, the CO2 will be transported by an existing pipeline to storage in the depleted Viking gas fields of the southern North Sea.

Future Technology
Phillips 66 is also exploring opportunities to include hydrogen refuelling and production as part of future phases for Humber Zero at the Humber Refinery. “Blue” and “green” hydrogen will be explored to reduce industrial emissions that cannot be reduced by using carbon capture.
VPI Immingham is also exploring the potential to produce more than 170,000 tonnes of “blue hydrogen” each year from a brand new facility adjacent to the current VPI Immingham CHP plant.
