Thermodynamics of Hydrogen Economy Systems and CCUS Streams

Online 14:00 BST

Repurposing existing oil and gas infrastructure for Carbon Capture, Utilisation, and Storage (CCUS) and hydrogen applications presents a myriad of complex challenges that demand serious attention. These hurdles encompass potential inaccuracies in flow measurement and heightened risks of corrosion and rock dissolution, which can lead to undesirable gas leakage. These issues are predominantly rooted in the inherent thermodynamic properties of CCUS and hydrogen-containing systems. Thus, a fundamental prerequisite entails acquiring an in-depth comprehension of the theoretical foundations and thermodynamic principles governing the entirety of the CCUS process and the hydrogen economy systems.

Effectively addressing these challenges requires the development of a robust model capable of accurately predicting the properties of H2 and CO2-rich streams under diverse operating conditions. Critical parameters such as density, speed of sound, and phase boundaries must be precisely determined to ensure precise flow measurement. Furthermore, this approach aims to establish safer and more secure transportation and storage processes for CO2 and hydrogen by proactively mitigating operating conditions conducive to corrosion and reservoir rock dissolution challenges. Therefore, cultivating an informed and comprehensive understanding of the thermodynamic intricacies, coupled with the formulation of an appropriate prediction model, will serve as a cornerstone in facilitating successful and sustainable implementations of CCUS and hydrogen technologies.
