By some estimates, a single container ship can cause as much pollution as 50 million cars on the road. That is because until recently, these ships have been largely unregulated. But new emissions laws mean the shipping industry has to clean up its act, and some companies are looking to hydrogen fuel cells to lower their environmental impact.

Sustainable Shipping For The Future

Several recent presentations and papers have looked at the practical applications for hydrogen fuel cells on ships,including a system that would provide 10 straight operating days of fuel and 5 megawatts of power, enough to turn two huge propeller blades. Another plan calls for a 1,500 passenger ferry that can also hold 2,200 meters of automobiles, with enough hydrogen storage for 48 hours of continuous use with zero emissions.
