Gas hydrates are ice-like solids composed of water and gas molecules, mostly methane and lighter hydrocarbons as well as CO2 or H2S. In nature, gas hydrates form at elevated pressure and low temperatures in oceanic sediments on continental margins and in polar sediments and permafrost areas. Huge amounts of gas are stored in gas hydrate deposits worldwide, providing a potential source of energy but also a potential problem as greenhouse gas emitters.
We determine the thermodynamic properties of mixed-gas hydrates under controlled conditions close to nature; we develop innovative methods for the production of methane gas from hydrate-bearing sediments and for the sequestration of CO2 in the form of gas hydrates in sediments.
