Natural Gas to hydrates for transport and back to gas

A while back I wrote a post HERE and HERE on collecting natural gas hydrates from the sea floor.  I was not really in favor of the idea because of the possible/probable dangers.  For good or bad like drilling at 5000ft for oil, extracting these frozen naturals gasses is going to happen so might as well examine the effects..

One of the often cited problems with natural gas as an energy source is that they are hard to safety transport over long distances because of the volatile and hazardous properties of the fuels.  A proposed solution is to turn the fuel back into a solid by freezing and applying pressure like at the bottom of the ocean where fuels like methane are in a solid and thus more stable state.

My concern in using this method of freezing and unfreezing is how much energy will be needed to convert a gas like methane into a solid.  The melting point of methane is about -297 F(162.5C) so an extremely cold environment would be need to convert and keep methane as a solid.  The other problem is that natural gas is another limited resource so putting lots of energy into collecting it is not a good long term energy strategy.

However, just like coal and oil, we will take natural gas as long as we can get it and so having a viable fuel transportation strategy is an important development.
