Workshop - CO2 hydrates for Carbon Capture, Utilization and Storage
Chair / Presidente: Ana Paula Ribeiro (PT), Karey Maynor (US)
This workshop will focus on the emerging role of carbon dioxide hydrates as a tool for carbon management within Carbon Capture, Utilisation and Storage (CCUS) strategies and circular economy frameworks. CO2 hydrates offer unique opportunities for dense, reversible CO2 storage, separation, and transport, as well as for integration with energy and resource management systems. Their potential relevance spans industrial CO2 capture, offshore and subsea storage, gas separation, and coupling with renewable energy and water systems. Through a series of concise introductory presentations, the workshop will provide an overview of the fundamental principles of CO2 hydrate formation, stability, and kinetics, followed by discussion of recent technological developments and system-level concepts. Particular emphasis will be placed on utilisation-oriented perspectives, including hydrate-based CO2 capture and separation, temporary storage and transport, and hybrid approaches linking hydrates with mineralisation, conversion processes, or energy storage. The session will actively engage participants in structured discussions to identify key scientific, technical, and economic challenges that currently limit large-scale deployment of hydrate-based solutions. By bringing together researchers and practitioners from chemistry, materials science, process engineering, and environmental systems, the workshop aims to clarify the realistic role of CO2 hydrates in future carbon management strategies and to define priority directions for research, development, and demonstration.
