Technological and Economic Challenges of Liquefied Hydrogen in Maritime Applications: Analysing Vessel Types, Tank Designs, and Retrofit vs. New Build Approaches in the LH2CRAFT Project

The trading pattern analysis together with the vessel and market restrictions identified under Task 2.1 (analysis of global trade), have been correlated with the case of liquified hydrogen onboard within task 2.4 (alternative containment types & designs). More specifically, key technological and economical challenges related to LH2CRAFT have been documented along with possible limitations. In an effort to reduce and categorize the limitations for the uptake of liquefied hydrogen in the maritime sector, an analysis between the variety of vessel types (cargo, tanker, RoPax, containerships etc.), the potential usage of LH2 onboard (fuel or cargo), the most appropriate tank type (Type A,B,C or membrane) and the design approach (retrofit or new building), has been established. The above-mentioned study showed that further examination of the most appropriate utilization of LH2 onboard will be required under task T4.4 (preliminary investigation of alternative CCS solutions integration). At the final stage of task 2.4, a GAP analysis on the technological and financial dimensions of the utilization of LH2 (either as cargo or as fuel) on either new building or retrofit designs has been highlighted.
