'We have no idea how stable potential methane hydrate will be in a warming climate if ice sheets thin.
[UKPRwire, Sat Aug 10 2019] "Commercial, transportation and heavy industries will be the leading sectors where the methane hydrate market will be dominant but currently it is at the nascent stages." Methane Hydrate Market: Introduction Methane Hydrate also known as methane clatharate, hydromethane, methane ice, fire ice, natural gas hydrate, or gas hydrate.
Methane hydrate is a naturally occurring clathrate in which a host lattice of water ice encloses guest molecules of methane.
The latest report on the global Methane Hydrate market suggests a positive growth rate in the coming years.
Also, it is extremely difficult and quite expensive to extract methane hydrate from the ocean floor -- careful attention is needed to prevent leakage of methane into the atmosphere.
The test is the first since Japan achieved the world's first extraction of gas in 2013 from offshore deposits of methane hydrate, a frozen gas known as "flammable ice".

[12] studied the effect of a series of surfactants on the growth rate of methane hydrate and gas storage capacity and found that sodium dodecyl sulfate might be the most suitable surfactant for methane hydrate formation.
More research also is needed to track the destabilization of methane hydrate by shifting ocean currents.
Figure 1 shows the molecular structure of a Structure I methane hydrate. Both Structure I and Structure II cages are about 85 mole percent water.
Water quantity in wet natural gas depends on its temperature while methane hydrate formation is a function of pressure and specific gravity [5].
TOKYO, Dec 25 (KUNA) -- Japan's Agency for Natural Resources and Energy (ANRE) announced Thursday it has successfully extracted samples of methane hydrate from the seabed of the Sea of Japan.
