The “guest exchange” of methane (CH4) by carbon dioxide (CO2) in naturally occurring gas hydrates is seen as a possibility to concurrently produce CH4 and sequester CO2. Presently, process evaluation is based on CH4−CO2 exchange yields of small

This study focuses on seafloor methane seep sites and their distribution in the northwestern part of the German North Sea. Methane seepage is a common phenomenon along marine shelves and known to occur in the North Sea, but proof of their existence w

The investigation of the gas hydrate system and hydrocarbon distribution were targets of IODP expeditions 372 and 375 on the Hikurangi Margin offshore New Zealand. Isotopic and molecular signatures clearly indicate a biogenic signature of methane at

Methane is the second most important greenhouse gas and, considering a period of 100 years, has a more than 30 times higher “global warming potential” than carbon dioxide. Emissions from the production, storage, distribution and use of fossil ene

We developed a new thermostated ring-shear-apparatus for investigation on hydrate- or ice-bearing sediments. A fluid inlet at the bottom of the static part of the cell and a fluid outlet at the top of the rotating half-cell allow exchanging and press

Investigations regarding the effects of particle size on gas hydrate growth are commonly carried out using glass beads, silica powder, and various clay minerals. Comparisons of different grain sizes of sands are less common as are natural samples. Si
