Fume Hood

Gas hydrate can be formed in sediment in several ways, but forming hydrate from methane that has first been dissolved in water is thought to generate pore-space gas hydrate distributions that most closely mimic those in nature. Shown above, water circulates in a fume hood between a low-temperate cylinder with high-pressure methane gas in contact with water, dissolving and transporting that methane over time through the gas hydrate growth and measurement chamber, where hydrate grows in sediment and properties such as permeability can be measured.
