(236f) Recent Advances and Prospects of Hydrate-Based Pre-Combustion Carbon Capture

Carbon capture, utilization, and storage (CCUS) technologies play a crucial role in delivering clean energy and combating climate change, particularly as electricity demand escalates alongside population growth and the rapid expansion of the electric vehicle market. A newly developed approach for precombustion carbon capture utilizing gas hydrates has drawn considerable attention because of its promising potential.

Hydrate-based precombustion carbon capture is a method that involves using gas hydrates, which are ice-like crystalline solids formed by water and gas molecules under specific pressure and temperature conditions, to capture carbon dioxide (CO₂) from fuel gases before combustion. The benefits of hydrate-based precombustion carbon capture are high capture efficiency, low energy consumption, scalability, the potential for CO₂ storage as hydrates, and compatibility with various fuel types. The major bottleneck that was impacting the scaling up of the hydrate-based precombustion carbon dioxide capture process is the slow kinetics of hydrate formation.

In this presentation, we present the overview of hydrate-based precombustion carbon dioxide capture from fuel gas mixture and our current research efforts to improve the kinetics by employing different reactor configurations. We also present the future directions to commercialize this technology.
