Cruise liners in particular emit large amounts of pollutants on route to the world’s natural – sometimes seemingly untouched – landscapes, or their diesel generators are running to power onboard systems while they are docked. However, now that shipping companies are switching to LNG, the market could see a change for the better. Fuel cells, too, could soon play an important part in the design of cleaner marine propulsion.
