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.

The use of fossil fuels and emission of greenhouse gases (GHG) from waterborne must be minimised as fast as possible to reach a climate-neutral society by 2050. A vital prerequisite of the decarbonisation is the rapid growth of low-carbon power sources and energy storage. To achieve this, the efficient integration in the shipboard power system requires the development of high-power components and protections, and more specifically DC-DC power converters and DC switchgear. Albeit DC primary grids have been deployed for several vessels, the secondary grid has remained substantially identical to traditional solution based on AC. There is an opportunity to unlock the capabilities and functionalities of novel components for secondary grids that can improve the safety and the operations on the vessel. These components, integrated with the power converters and the protections of the primary grids, will reduce the risks of blackouts connected to faults and improve the reliability of the power supply. ALL-DC-SHIPS has devised a comprehensive strategy to address the challenges faced by shipowners, systems integrators and ship operators that includes: 1) development of new modular power converters with wide bandgap devices for primary DC grids 2) high-density power converters for secondary DC grids 3) innovative DC protection systems for primary and secondary DC grids 4) implementation of advanced algorithms for real-time ship energy management 5) rigorous testing and validation methodologies for the vessel demonstrator 6) providing recommendations for relevant use cases above 5,000 GT. ALL-DC-SHIPS will contribute to enable low-emission waterborne transport and technology transition for a resilient and sustainable future of the maritime sector.

TRUSTEE project aims at supporting the European roadmap to deploy the ZEWT providing the decision makers and the wide stakeholders community with a comprehensive and science-based set of knowledge and recommendations built on an evidence based approach, founded on: - clarity and comprehensiveness of foresight scenarios in 2030 and 2050 where ZEWT will be deployed - a comparative multidimensional assessment framework incorporating environmental, social, technological, financial and operational aspects, including safety and security aspects for workforce and citizens - a robust validation roadmap with an equitable representation of direct and indirect stakeholders. TRUSTEE is built on the following objectives: - Define and validate future European ZEWT wide ecosystem at 2030 and 2050 time horizons through foresight scenarios - Detail and validate the most promising ZEWT Use Cases for the 2030 and 2050 target horizons - Build and validate a multi-stakeholders and cross-sectorial assessment framework for system components and overall ecosystems underpinning the Zero Emissions target in the European water transport sector - Identify systemic and sectorial barriers challenging the ZWET targets and defining recommendations for its timely deployment - Create a common knowledge background among all direct and indirect stakeholders for ZEWT targets timely achievement. Thanks to a consortium with relevant expertise and strong institutional liaison with all the ZEWT stakeholders, TRUSTEE will achieve the desired impact delivering actionable Open Access Results: - ZEWT 2030 and 2050 foresight scenarios - ZEWT technology readiness review - Comparative analysis framework for ZEWT use cases assessment, combining environmental, technical integration, operational, societal and financial indicators - ZEWT barrier analysis - Most promising ZEWT Use Cases - Recommendations for ZEWT standards, regulations and policy development - ZEWT open access learning pack.

New energy storage technologies can significantly improve the performance of batteries for zero-emission waterborne transport and reduce R&D and operational costs. V-ACCESS brings together expertise on supercapacitors, superconductive magnetic energy storage systems (SMES), design and control of shipboard power systems, power electronics, lifetime cycle analysis, and ship classification to increase the technology readiness level (TRL) of hybrid storage systems, i.e. combining a battery with either supercapacitors, SMES, or both. They will be integrated into an innovative DC shipboard microgrid to control flexibly the power sharing between the different energy storage technologies. The proposed technologies are analysed from the components levels, already tested and validated at TRL3, and modelled into the vessel's power system, also using control hardware-in-the-loop simulators. Then, the individual components are assembled together and integrated into a realistic shipboard power system available at the ETEF facility of the University of Trieste to reach TRL5. Business models and standardisation needs will be deeply analysed and measures to unlock existing barriers and will be promoted in parallel to the technical knowledge generated from the project to ensure further exploitation of the project results and the definition of the steps to upscale the design of the V-ACCESS system, paving the ground for a full-scale demonstrator to be developed after the end of this project and bringing the proposed technologies closer to market.
