Hydrates are known in other contexts such as petroleum drilling and production operations as a nuisance. Especially in deepwater conditions, they can plug pipelines and threaten drilling well control. Also, hydrates could have some global warming implications. As sea levels rise, hydrates in permafrost regions are released to the atmosphere. Methane, as a green house gas, then could encourage further global warming create a positive feedback.
I think as energy demands increase, production from hydrates is a very real possibility. There are currently no economic hydrate projects, but the government is actively funding research.
