Will methane hydrates ever become a commercially extracted energy source?

NOAA estimates hydrate deposits hold roughly twice the carbon of all proven coal, oil and conventional gas reserves combined, but no country has moved past experimental test extraction. Whether stable, economic extraction is achievable at all is unresolved, not merely undocumented: disturbing a deposit risks a large methane release and submarine landslides, so the open question is as much about whether pursuing it is prudent as whether it is possible.
