(236b) Carbon Dioxide Sequestration Via Gas Hydrates: A Potential Pathway Towards Decarbonization

Climate change is known to be dominantly caused by the increased concentration of greenhouse gases in the atmosphere, in particular carbon dioxide (CO₂). The clathrate hydrate process has been demonstrated over the years as promising technology for innovative applications like natural gas storage, carbon dioxide capture, seawater desalination, cold energy storage etc. CO₂ hydrate, a solid compound made of molecular CO₂ enclathrated in crystalline lattices formed by water molecules, is an attractive option to capture and for long-term CO₂ sequestration. Methane hydrates in oceanic sediments have been stable for millions of years. As a natural analog, is it possible to store CO₂ in the form of hydrates in oceanic sediments forever? In this presentation, the state of the art on clathrate hydrate technology pertaining to carbon capture and storage will be discussed in detail. Furthermore, future research and development opportunities and pathways for commercialization will be discussed.
