Pollution on the high seas is a reality and cruise ships contribute heavily to it. To reduce their pollution footprint, cruise ship operator, Royal Caribbean is developing a class of cruise ships called the Icon, which will run on liquified natural gas fuel cells reports Engadget. This is expected to dramatically reduce harmful emissions from the ships and also reduce their dependence on having to dock at ports which offer natural gas refueling stations.
Royal Caribbean will begin testing the new vessels in 2017 but the first of the Icon class of ships will only be able to sail the seas in 2022 and the second in 2024. Fuel cells will only be more helpful as cruise ships become larger and require more fuel to power them. Clearly Royal Caribbean has a good vision for a reduced emission future.
