Those crystals, known as methane hydrates, contain natural gas but so far releasing that fuel has been an expensive proposition.
The drilling has its environmental critics, but there’s also a climate bonus: The technique requires injecting carbon dioxide into the ground, thereby creating a new way to remove the warming gas from the atmosphere. 
'You're storing the CO2, and also liberating the natural gas,' Christopher Smith, the Energy Department's oil and natural gas deputy assistant secretary, told msnbc.com. 'It's kind of a two-for-one.'"

I've never heard of this before. It sounds better than natural gas actually, which would be one step ahead at any rate.  Gotta keep an eye on this.
