The LH2CRAFT project is a 48-month initiative involving 14 partners focused on integrating and validating Liquid Hydrogen (LH2) in maritime transport. Coordinated by HYDRUS and including the NTUA among its experienced consortium, the project develops next-generation, sustainable, commercially attractive, and safe long-term storage and long-distance transportation of LH2 for commercial vessels. This includes the analysis of alternative conceptual designs with early-stage safety and risk assessments of the cargo containment system (CCS) exceeding currently demonstrated sizes. The CCS will achieve Approval in Principle (AiP) and general approval by a major classification society, with demonstrations involving detailed design, construction, and testing of a reduced-size prototype. LH2CRAFT will also develop a preliminary integrated ship design, perform cost estimations, and achieve reduced boil-off rates of 0.5% per day. A life cycle model will compare different new design or retrofit strategies, and a Life Cycle Assessment (LCA) of the large carrier will evaluate the environmental impact from cradle to grave, identifying sustainability and recyclability activities. The project emphasizes environmental compliance, risk assessments, and regulatory proposals to support LH2 adoption, aiming to achieve FuelEU Maritime 2040 targets by reducing greenhouse gas emissions and promoting LH2 usage through robust dissemination and exploitation strategies.
