Periodic Reporting for period 1 - V-ACCESS (Vessel Advanced Clustered and Coordinated Energy Storage Systems)

Période du rapport: 2023-02-01 au 2024-07-31

Résumé du contexte et des objectifs généraux du projet

V-ACCESS aims to improve battery performance for zero-emission waterborne transport by integrating supercapacitors and superconductive magnetic energy storage systems (SMES) into innovative DC shipboard microgrids. The project brings together experts to increase the technology readiness level (TRL) of hybrid storage systems, combining batteries with supercapacitors, SMES, or both. These technologies will be analyzed, modeled, and integrated into realistic shipboard power systems to reach TRL5. Business models and standardization needs will be explored to ensure further exploitation of project results and pave the way for full-scale demonstrators.

Travail effectué depuis le début du projet jusqu’à la fin de la période considérée dans le rapport et principaux résultats atteints jusqu’à présent

WP1: Conducted comparative assessment of storage technologies for vessels, evaluating power density, energy density, and expected lifetime. Reviewed zero- and low-emission ship types, identifying applications for hybrid energy storage solutions. Analyzed benefits across 13 vessel types, selecting three use cases: an electric ferry, a trawler, and an OSV. Assessed hybrid storage configurations, optimizing designs through numerical scripts.
WP2: Focused on integrating Energy Storage Systems (ESS) into ships, addressing environmental, naval architecture, and regulatory requirements. Ensured ESS components can withstand marine conditions and assessed weight, volume, and space allocation. Used virtual prototyping to fit ESS within existing structures while complying with regulations. Developed a 3D virtual prototype for a ferry vessel, positioning SMES and supercapacitors in designated rooms.
WP3: Analyzed vessel systems and energy storage characteristics. Reviewed DC power system topologies, estimating theoretical short-circuit currents. Explored converter topologies for supercapacitors and SMES, ensuring bidirectional power flow. Studied control strategies, resulting in single-line diagrams. Defined simulation methodology for energy storage in zero- and low-emission vessels. Specified characteristics for lab demonstrations, scheduled for late 2024 and mid-2025.
WP4: Evaluated hybrid energy storage systems (HESS), focusing on environmental impact, costs, efficiency, comparison to batteries, and implementation. Conducted life cycle assessment (LCA) following ISO 14040 standards. Cost analysis showed batteries at €500/kWh TCC, with SMES and supercapacitors higher. Energy efficiency modeling indicated HESS improvements. Analyzed regulatory impact for HESS adoption in marine vessels.
WP5: Aimed to advance Technology Readiness Level (TRL) of novel storage systems. Market study identified entry barriers through cost of goods sold (COGS) assessment. Results suggest potential fivefold COGS reduction in supercapacitor production. Standardization efforts focus on integrating new systems in five areas: electrical, control, auxiliary systems, mechanical factors, and safety. Developing regulatory framework and training programs for zero-emission vessel operation and maintenance.
