Staff Profile

My research interest is decarbonising industrial processes and energy generation, primarily through transportation by pipeline of carbon dioxide (CO₂) for Carbon Capture and Storage (CCS) schemes and hydrogen for use as an alternate energy source.

Some examples of previous research topics:

• Material and specification requirements for novel pipelines
• The impact of impurities on CO₂ pipelines and shipping
• Pipeline failure frequency and consequence analysis (including developing analytical and CFD CO₂ building ingress models)
• Hydraulic network design
• CCS network flexibility
• Pipeline fracture propagation
• The effect of injecting cold CO₂ on the surrounding rock
  

Carbon dioxide transportation

Hydrogen strorage and transportation

Mathematical modelling

More specifically:

• Transportation network design and optimistation
• Pipeline consequence analysis and failure frequency
• Dispersion modelling of CO₂
• CO₂ and H₂ compression and liquefaction
• Hydraulic modelling and network flexibility
  
• Fracture propagation
• Heat transfer and phase behaviour
