Gas Hydrates

Gas hydrates are crystalline solids that consist of gas molecules, usually methane, surrounded by water molecules.  The gas molecules are densely packed in a crystalline structure so that hydrate deposits can store vast quantities of methane.  Estimates of the amount of carbon bound in gas hydrates are almost twice the amount of carbon found in all known fossil fuels on Earth; hence, hydrates represent a dominant unconventional energy resource.  Though these hydrates are abundant worldwide, particularly in Arctic regions and in marine sediments, there is much to learn about how they form, evolve, interact with surrounding sediments, and affect environmental conditions when extracted.  EMD members are active in chairing technical sessions, presenting talks and posters, and promoting gas hydrate research and development efforts. -- Laura Wray
