Abstract:

For the past few years, ICCT has been investigating the potential for liquid hydrogen (LH2) made from renewable electricity to power transpacific container shipping. Most recently, ICCT estimated that container shipping could generate demand for over 730,000 tonnes of LH2 per year at Pacific ports. This paper builds on that work by considering the role that Aleutian Islands ports in Alaska could play. The authors estimate both “latent demand” from the existing fleet that already calls on the Port of Dutch Harbor, one of the busiest fishing ports in the United States, and demand from oceangoing vessels that would require an additional refueling stop if operated on LH2. This includes developing new methods to characterize the operations and fuel use of fishing vessels, which are poorly represented in existing models.
