CCUS and Hydrogen Economy

CCUS and Hydrogen Economy: Going Through Transportation Media with Chemical Thermodynamics



Efficiently reusing and repurposing existing oil and gas infrastructure for Carbon Capture, Utilisation, and Storage (CCUS) and hydrogen applications presents several challenges that demand careful consideration. Among these challenges are the potential errors in flow measurement and the elevated risks of corrosion and rock dissolution, which can result in undesirable gas leakage. These issues stem, to a considerable extent, from the thermodynamic properties inherent to CCUS and hydrogen containing systems. Therefore, a foundational step is to thoroughly comprehend the underlying theory and thermodynamics governing the entire CCUS process and hydrogen economy system.

To address these challenges effectively, it becomes imperative to develop a robust model that can accurately predict the properties of H2 and CO2-rich streams at both ends. Critical parameters, such as density, speed of sound, and phase boundaries must be accurately determined to ensure precise flow measurement. Additionally, this approach aims to establish safer and more secure CO2 and hydrogen transportation and storage processes by pre-emptively avoiding operating conditions that would contribute to corrosion and reservoir rock dissolution challenges. Therefore, an informed and comprehensive understanding of the thermodynamic aspects, coupled with the development of an appropriate prediction model, will be instrumental in fostering successful and sustainable CCUS and hydrogen implementations.
