This study models the cost of different pathways for delivering low-carbon hydrogen from likely producing regions to Europe’s largest seaport, the Port of Rotterdam in the Netherlands. Specifically, the analysis considered pipeline transport of gaseous hydrogen from Algeria and Norway and maritime (ship) transport of either liquid hydrogen, ammonia, or a liquid organic hydrogen carrier (methylcyclohexane) from Norway, the Arabian Gulf region, and North and South America. Estimates of overall cost per kilogram of hydrogen delivered to Rotterdam were developed for each of three total import volumes…
