REFEST is focused on the most promising scalable technologies with low CAPEX, easy to deploy and suitable to be installed in a broad range of traditional fishing ships to provide hydrodynamics, electrical power management, alternative propellers, solar electricity generation and propulsion (batteries), sensoring and digitalization, hull appendages and air lubrication. REFEST aims to achieve TRL6 – procedures and technologies to secure the reduction of fuel consumption and GHG emissions up to 40% reduction compared to the original design. The solutions proposed will be designed to ready to deploy in a broad range of small fishing vessels and they are characterized by a low CAPEX and OPEX requirements to significantly reduce the payback time). Ensuring upscaling of the proposed solutions after project implementation till 2029. The main innovations are summarized as follow: i) Innovative design by the use bulbs and spray rails that allow to improve hull hydrodynamics, to minimize the water friction and reduce external and underwater noise, ii)Recyclable thermoplastic composites for maritime applications, iii) Air lubrication systems, iv) Integration of multi-functional optical fibre sensors for hull fishing ships monitoring, v) Propulsion systems based on RIM drive solutions and its hybridization with current diesel engines, vi) Battery pack optimized to be used under cold weathers and with high percentage of reusable/recyclable components, vii) BMS, EMS, and PMS to maximize the energy consumption in the vessel, viii) Cloud-based Eco-driving software and ix) Low-weight and flexible silicon PV panels. viii) Three retrofit demo traditional fishing ships in North Sea (Denmark & Norway) and Baltic Sea (Lithuania).

GAMMA features 16 of the most important innovators and disruptors in the maritime sector. GAMMA partners will design, test and validate the very best energy conversion technologies and integrate them on an ocean-going vessel on international sea / ocean routes. The main goal of GAMMA is to support commercial vessels in their energy transition by demonstrating the safe integration of fuels (biomethanol and NH3), and fuel systems (biomethanol reformer, NH3 cracker and 1MW low-temperature PEM fuel cell) to provide an Ultramax bulk carrier with substantial emissions savings by performing steam reforming and ammonia cracking instead of combusting Very Low Sulfur Fuel Oil (through the replacement of auxiliary engines, which will stay as a back-up). Among the objectives of the project, GAMMA will (1) successfully retrofit the vessel, (2) show that ship operations can be handled in a safe manner and (3) test the availability of the sustainable fuel value chain for maritime vessels.

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.

NEMOSHIP ambitions to contribute to the European Partnership “Zero Emission Waterborne Transport (ZEWT)” objectives by providing new deployable technological solutions needed for all main types of waterborne transport to reach a “net zero emission” by 2050. To reach this goal, NEMOSHIP will: - develop (i) a modular and standardised battery energy storage solution enabling to exploit heterogeneous storage units and (ii) a cloud-based digital platform enabling a data-driven optimal and safe exploitation, - demonstrate these innovations at TRL 7 maturity for hybrid ships and their adaptability for full-electric ships thanks to: (i) a retrofitted hybrid Offshore Service Vessel (diesel/electric propulsion), (ii) a newly designed hybrid cruise vessel (LNG/electric propulsion) and (iii) a semi-virtual demonstration for two additional full-electric vessels such as ferries and short-sea shipping. All results will be built upon a treasure chest of 18 years of ESS operation data. Thanks a very ambitious exploitation plan, accompanied by very large dissemination actions, the NEMOSHIP consortium estimates that these innovations will reach the following impacts by 2030: (i) electrification of about 7% of the EU fleet; (ii) generate a potential revenue of €300M thanks to the sales of the NEMOSHIP products and services; (iii) reduce EU maritime GHG emissions by 30% compared to business as usual (BAU) scenario; and (iv) create at least 260 direct jobs (over 1000 indirect). The NEMOSHIP consortium is composed of 11 partners (3 RTO, 1 SME, 7 large companies) and covers the whole value chain, from research-oriented partners and dissemination and exploitation specialists to software developers, energy system designers, integration partners, naval architects and end-users.
