What effect does CO2 have on a subsea pipeline?

Crondall Energy welcomes student Ciaran Reid to the team to carry out some academic research into the subsea transportation of carbon dioxide. Ciaran is reading Chemical Engineering at the University of Strathclyde and previously worked at Crondall Energy on a summer placement in 2019.

Ciaran’s work will compliment the company’s focus on the renewable energy market as we see the energy transition giving us reason to be optimistic about the future of the industry. Ciaran recognises the huge strides being taken in novel technologies driving forward the decarbonisation of our planet and carbon capture becoming increasingly feasible and playing a crucial role in our future as a net zero society. Therefore the team at Crondall Energy is delighted to welcome Ciaran back on a 5 month placement to carry out a research project into the subsea transportation of carbon dioxide.

Ciaran said “CCUS will only succeed if the arteries that link the system together are successful. Crondall Energy is quickly becoming an expert in this field and have been appointed as technical advisors to the UK government on CCUS, making it an extremely exciting time to join them for this project. Through a recent internship at BP I learned that there is a genuine appetite and progress towards the transition to net zero projects within the major oil & gas operators and so I’m extremely excited to get the opportunity to play a part in finding solutions to the complex technical CCUS problems we are facing in the sector".

The project aims to analyse the effect that different compositions of CO2 rich mixtures will have on the subsea pipeline over time. Research into current and future upstream carbon capture techniques will be carried out to find a range of potential compositions of CO2 that may require transport over a system’s lifetime. The operating conditions within typical pipeline and well injection systems for CO2 will be analysed. Combining the phase models and operating models should allow the location of potentially unstable regions to be found.
