CO2 in, CH4 out! A Useful Concept for Hydrates?

Natural gas hydrate deposits are found on all active and passive continental margins as well as in permafrost regions and deep lakes. Their worldwide occurrence and the large quantities of natural gas they contain make them appear to be both an energy source and a potential climate factor. In order to use the methane bound in gas hydrate deposits in the most climate-neutral way possible, it has been proposed to combine the extraction of natural gas from the gas hydrates with the injection of CO2: The methane gas trapped in the gas hydrates is to be replaced by CO2. In recent years, a large number of experimental and numerical simulations have been performed to understand the interaction between injected CO2 and the hydrate-bearing sediment. This webinar summarizes the main results and highlights the challenges and potential opportunities of the method.
