The IMO’s previous goal was a 50 percent reduction by 2050 in comparison with 2008 levels. At the same time, it’s becoming apparent that alternative-fuel solutions we’re looking at have big drawbacks, and that producing these fuels will take a lot of green power that will be needed to replace coal and gas on shore.

For this reason the anodes of fuel cells need platinum to prevent rapid degradation. The cost of platinum makes hydrogen fuel cells an expensive proposition even in comparison to lithium-ion batteries. Hence, hydrogen fuel cell vehicles are intrinsically more expensive than pure battery-electric cars. .
