POSEIDON main objective is to demonstrate the applicability of 3 innovative fast-response ESS in waterborne transport (Supercapacitors, Flywheels and SMES) addressing their on-board integration, cost-competitiveness, efficiency, and safety, in relevant environments. To achieve it, the following specific objectives have been defined: SO 1. To build and marinize 3 innovative ESS (SMES, Supercapacitors, and Flywheel) SO 2. To demonstrate their operation in a maritime environment of a containerized system including the 3 developed ESS systems. SO 3. To establish a refined metrics Levelized Cost of Storage (LCOS) tool for cost assessment and comparison of ESS for different waterborne segments. SO 4. To elaborate a complete lifecycle analysis of the 3 developed ESS. SO 5. To analyse potential integration with other disruptive technologies, such as hydrogen, rigid sails, and reversible hydrokinetic generators. SO 6. To determine safety issues, potential long-term risks and to propose regulatory solutions for the 3 ESS. To achieve SO1 and 2, POSEIDON will contribute with 3 Innovative Outputs (IO) that will demonstrate the potential applicability of Fast Response Energy Storage Systems (FRESS) in the maritime industry. IO1. Marinized SMES based on CERN high-field superconducting magnets IO2. Slow Flywheel for waterborne transport IO3. Supercapacitor based ESS for marine applications SO3, 4, 5 and 6 are focused on the main barriers that must be overcome to achieve the penetration of alternative ESS in the maritime industry. To this purpose, POSEIDON will develop 3 innovative tools: Tool1. a refined metrics Levelized Cost of Storage (LCOS) tool for ESS cost assessment and comparison. Applicability report of FRESS to different waterborne segments. Tool2. LCC and LCA analysis of FRESS technologies applied to the waterborne segment. Tool3. Disruptive technologies assessment: complementarity with hydrogen and solid sails

Proton Exchange Membrane Fuel Cells are considered as one of the solutions enabling long-term sustainable transport, however, incumbent systems provide electric power outputs below 200 kW. To cater to the need of the heavy-duty transport sectors, the development of next generation of Fuel Cell systems aims at durable PEMFC stacks offering power output between 250 and 500 kW. To support this development, the H2UpScale project aims to design, build, test and validate key BoP components for PEMFC systems generating more than 250 kW electric power suitable for heavy-duty transport applications (aviation, maritime, on-road long-haul). H2UpScale brings together 3 research organisations, 2 academic and 11 industrial partners, including BoP manufacturers and OEMs. The project will identify application-specific requirements, that will then drive the requirements, development and optimization of 3 standards for modular and scalable PEMFC architectures ≥250kW (electrical power supply architectures & waste heat management system designs).The BoP components in focus include the hydrogen ejector, H2 recirculation pump, H2 leakage sensor, air compressor, cathode air filter and air humidifier, water separator, exhaust resonator, coolant heat exchanger and coolant medium. The targeted advancements for BoP components include efficiency and durability improvements, weight and volume reduction, and architecture simplification. The components will be designed to be compatible with both single- and multi-stack platforms, with scalability and modularity in mind, facilitating their integration into multi-MW scale systems. Selected full-scale BoP components will be validated on a Hardware-in-the-Loop test bench and a techno-economic analysis of the potential impact of the developed BoP components on the HD markets will be performed. With these main targets, the aim for H2UpScale is to provide critical technological bricks enabling the creation of a TRL7 demonstrator from 2027 onwards.

Europe's vast maritime domain faces challenges in situational awareness and border security due to dynamic operations and rising maritime crimes. Current surveillance technologies lack cost-efficient, wide-ranging coverage, leaving gaps in EU monitoring. MARCONNECT introduces the Vessel-Connected Services (VCS), a disruptive solution that transforms civilian vessels into active contributors to a real-time, integrated maritime surveillance network. By securely and voluntarily sharing their outward-looking sensor data (e.g., radar, sonar) with Coast Guard Authorities, civilian vessels become valuable assets in enhancing maritime situational awareness. In return, vessel owners gain access to tailored third-party services of their interest and real-time connectivity, creating a synergetic ecosystem. The main end-users of the VCS solution include Coast Guard Authorities, extending also to law enforcement agencies , who will benefit from a dynamic and scalable maritime security solution, and maritime operators across the EU, while private sector stakeholders benefit from anonymised, aggregated data insights to improve their businesses. The impact of the VCS solution is profound, resulting in a significant expansion of maritime surveillance coverage, strengthened ability to detect and respond to maritime threats, complementing existing maritime intelligence services. MARCONNECT capitalises on the trend of decreasing maritime communication costs, accelerating this shift by enabling broader and affordable access to real-time connectivity. This vision is enabled by an experienced consortium of relevant Coast Guard Authorities and Law Enforcement, key maritime industry players, and leading SMEs and RTOs with a proven track record in border security, uniquely positioned to transform Europe’s maritime security landscape and strengthen its borders

The market conditions and the regulatory framework for the shipping industry and shipyards are changing profoundly. In response, shipyards need to build up the capacity to assess the environmental footprint of their yard-activities and the ship to inform their stakeholders in a transparent, understandable, comprehensive, and trustworthy way. While the environmental footprint of the operational phase of a ship can be covered sufficiently by existing standards, the non-operational footprint of the shipyard processes and the integrated materials and components remain a black box. It is the ambition of this project to drastically change the as-is situation and to make the impact measurable and thereby drive progress toward circular, zero impact shipping over the full circle of life of a ship. Therefore, CirclesOfLife will develop, test, and validate a general methodology and framework applicable to all European shipyards enabling to close the gaps in assessing the environmental performance of the shipyards and the ships they design, build, maintain, retrofit or recycle. CirclesOfLife will go beyond state of the art by defining a scientifically sound SEPI-methodology and Cradle2Cradle Ship Passport and will test and validate its applicability in day-to-day business of shipyards and suppliers in several use-cases, ranging from new building- to repair-and maintenance- to recycling yards. Moreover, CirclesOfLife follows a clear pathway towards market introduction and societal impact supported by Surfrider and ShipBreaking Platform as independent and trustworthy NGO’s. Based on the described measures, CirclesOfLife pursues to offer a widely accepted standard enabling shipyards, maritime equipment manufacturers, shipping companies, finance institutions and other stakeholders to compare the environmental footprint of ships and shipyards

FLEXSHIP will facilitate the transition of the waterborne sector towards climate neutrality by delivering a digital green concept for electrification of vessels consisting of a Green Digital Twin (GDT) for designing fit-for-purpose vessel electrical grid architectures and integrating a large battery capacity system into two existing vessel (DEMO 1 & 2) electrical systems, a compact, low-weight, modular and simple, high-efficiency battery system, and a safe integration guide of the system onboard ensuring system interoperability The overall goal of FLEXSHIP is to develop and validate safe and reliable, flexible, modular, and scalable solutions for electrification of the waterborne sector. This includes the reliable design and development of modular battery packs; safe on-board integration including the battery system and its associated electrical distribution grid into the vessel’s existing power grid; optimal design of energy management system (EMS) to maximise the operational flexibility and energy efficiency (both full-electric and hybrid), and smart control for improved lifetime of the battery system and critical power components. The objectives will be achieved by 8 WP and 16 partners within 48 months. In WP1 identification of specification and mapping of requirements will be done. In WP2 the vessel electrical architecture will be designed and optimised by means of the Green Digital Twin. In WP3 the development and optimisation of individual components and sub-systems will be done and the testing of the system at component/sub-system level will consist of hardware-in-the-loop (HiL) and software in the loop (SiL) tests in WP4. The full FLEXSHIP system will be tested in two demonstrations in WP5 with minimum 150nm sailing distance and in WP6 contributing to 300nm by green digital twin and achieving sustainability analysis and business plan. In WP7 the full system will be evaluated in an exploitation strategy. The innovations will be brought from TRL4/5 to TRL7.
