@stevenr597 That's an interesting view. I agree that LNG-powered ships reduce pollution, which is why they are being designed this way, but I didn't realize that it's not as "perfect" as it may seem. I guess this power source is similar to that of an electric car, lasting for shorter distances and more difficult to find spots for fueling. Do you have another type of ship power you would think is a better alternative than LNG? 

Every power source has its advantages and disadvantages.  I do not think that we will every see Lithium Ion powered cruise ships.  But what may be promising would be Hydrogen powering fuel cells which would generate electricity.  

LNG is cleaner burning and definitely reduces the pollution from the ships.

  But it is not the perfect vehicle to power cruise ships.  As was stated it must be stored under pressure.  In most ports there are minimal if any facilities to fuel up the ships.  In Port Canaveral the Mardi Gras is refueled by barge with the LNG floated down from Gorgia.  In addition, the energy content of LNG is less than that of Diesel, so the range of the ship is shorter.
