1. Relevant Project Milestones and Work Performed
1.1. MS1: Experiments Launch:
Exogenous studies were performed to formalize the operational profile and vessel typology, as well as formalize activities/knowledge/competencies in parallel towards the 4 pillars for the entire project.
1.2. MS2:
Main functional and technical requirements were published in project deliverables D1.1 D2.1 D2.2 D3.1 D4.1 and D5.1 with an overview of the work performed to date in the subsequent deliverable sections. Additional details can be found in the Milestone 2 Confidential Internal Consortium Report (Available upon request).
D1.1: Project Concept Functional Scenarios Definition and Initial Safety Plan for each scenario (Small/Medium/Large).
D2.1: Functional and Technical Requirements including the Overall classification of system requirements for each vessel scenarios.
D2.2 Description of the LincoSim HPC simulation platform, including requirements for the virtual towing tank which will be used to support project design.
D3.1 Preliminary Safety System ́s Definition which presents a discussion of the state of the art of safety systems for gas and hydrogen powered naval solutions. Requirements are mentioned for different perspectives throughout the document, but more precise indications will be available in further deliverables of this WP according to design and general choice during the project.
D4.1 Selection of materials and components for experimental testing and test plan, with particular emphasis on scenario application and identification of potential pollutant and operational influences.
D5.1 Functional, Technical and Operational Requirements which includes the capital concept and data concerning bunkering functional and technical requirements.
1.3. MS3:
Reports on the intermediate results from the first round of experiments serving as a learning basis for the following cycles of experiments. Additional details can be found in the Milestone 3 Confidential Internal Consortium Report (Available upon request).
Task 2.2: Activity in progress. Rebuilt and refactorization of computational back-ends ongoing, new modelling functionalities defined and implementation started; first preliminary validations performed.
Task 2.3: Small and Medium Scenarios preliminary general arrangements: technical data including LOA, beam, depth, draught, passengers and crew capacity, cars, and trucks (for Medium Scenario); 2D plan and side views and preliminary 3D model of exterior.
Task 2.4: Preliminary components scheme for Small and Medium Scenarios: hydrogen tanks (main dimension, capacity, volume, and onboard arrangement), FC stacks (main characteristics, dimensions, kW, and onboard arrangement). Subsystem for H2 distribution, bunkering interfaces, and reform under evaluation.
Task 2.5: Assessment of current Medium scenario reference vessels onboard energy system and power demand.
Task 3.1 and 3.2: Emergency hydrogen discharge CFD analysis is in progress, first simulation results from simplified model should be ready by 06.2022.
Task 4.2: Material and component testing with multi-single-cells (MSC), Test stand modifications & building of test capabilities started. Expected 09.2022.
Task 4.3: A literature review and review of results and lessons learned from past projects such as MARANDA, HYDRAITE and FLAGSHIPS is being performed to evaluate knowledge gaps regarding contaminants. The test plan for fuel cell system components testing (e.g. hoses and valves on the fuel cell) is underway to quantify the contaminant species with ex-situ leaching tests and analytical means. The reference tests will also be done on the cathode side for relevant materials, especially hoses.
Task 5.3: A comprehensive review of hydrogen bunkering processes has been completed. Adjustments to COSSMOS models for the decisions made over the bunkering system and operation are being planned.
