Contribution to wider strategies and policies:
- EUStrategyAdriaticIonianRegion Project clearly contributes to EUSAIR flagship Pillar 2 Connecting the region - The Adriatic-Ionian Multi-Modal Corridors with its overall objective to promote green/smart port hubs concept. Flagship's Indicative actions recognize seaports in the A-I Region, as a key priority in pursuing resilience to climate change in line with the goals and objectives of the European Green Deal. By this flagship, transition to the new ‘zero emission’ era should be further incentivised, including exchange of good practices regarding soft and hard environment-friendly solutions for a greener, safer and more efficient transport system, which is exactly what we aim with this project, ie. empower introduction of green hydrogen refuelling infrastructure into port infrastructure, promote green hydrogen fuelled vessels for passenger transport in programme area and exchange solution for planning of green transition in marine transport using green hydrogen technologies in programme area and beyond, including other countries in the A-I Region.
- Project also contributes to EU Strategy for the Adriatic and Ionian Region (EUSAIR) pillar 1 Blue Growth specific objective 1: “To promote research, innovation and business opportunities in blue economy sectors, by facilitating the brain circulation between research and business communities and increasing their networking and clustering capacity”, and its flagship Topic 1 - Blue technologies and indicative action - R&D&I platforms on green sea mobility (innovative propulsion modes and fuels). The project will connect research and expertise institutions as PPs in programme area to develop and disseminate new solutions for green sea mobility based on green hydrogen as marine fuel.
- EuropeanGreenDeal The European Green Deal and its European Climate Law calls for a 90% reduction in greenhouse gas emissions by 2050 from all modes of transport, and this includes maritime transport. This project will directly contribute to this goal by empowering cross-border transition to green sea mobility and enable programme area actors to catch up in the adoption and application of new technologies and solutions based on the use of green hydrogen as a fuel in maritime transport.
- Other Sustainable Blue Economy Strategy
- Communication on “A new approach for a sustainable blue economy in the EU: Transforming the EU’s Blue Economy for a Sustainable Future” recognizes sea ports as crucial to the connectivity and the economy of regions and that their future lies in developing themselves as energy hubs for integrated electricity, hydrogen and other renewable and low-carbon fuels systems and for industry as industrial clusters. Our project clearly contributes to these objectives, not only by demonstrating solutions for greening maritime routes in programme area with introduction of hydrogen as marine fuel, but also by making the industry and stakeholders in programme area aware of investment opportunities in hydrogen-based solutions.
- Other A hydrogen strategy for a climate-neutral Europe
- A hydrogen strategy for a climate-neutral Europe objective is to boost the demand for clean hydrogen coming from industrial applications and mobility technologies. It recognises that for sea shipping, hydrogen can become an alternative low emission fuel. By promoting usage and application of green hydrogen in maritime transportation we contribute with this project to boost demand for clean hydrogen as set in this strategy.
- Other Sustainable and Smart Mobility Strategy
- In its 2020 communication “Sustainable and Smart Mobility Strategy - putting European transport on track for the future”, the main driver for the transport sector growth for EC is greening mobility based on abundance of refuelling infrastructure for zero-emission vehicles and supply of renewable and low-carbon fuels. The target set for 2030 it that zero-emission vessels will become ready for market, something in which our project fully contributes with focus on programme area and its resources and competences. The increased deployment and use of hydrogen in maritime transport must go hand-in-hand with the creation of a comprehensive network of refuelling infrastructure to fully enable the widespread uptake of low- and zero-emission vessels, which is exactly what this project will deliver on cross-board level. With this project we fully contribute to the Sustainable and Smart Mobility Strategy by making CB and regional maritime transportation more sustainable by ensuring that the sustainable alternatives (ie. hydrogen fuelled vessels and refuelling infrastructures in ports) are available in the programme area and by pushing the right incentives and investment plans to drive this transition.
- Other EU mission "Restore our Ocean and Waters"
- The project contributes directly to EU mission "Restore our Ocean and Waters", its 3. Specific objective to make the sustainable blue economy carbon-neutral and circular and its targets to eliminate greenhouse gas emissions from maritime economic activities in the EU (particularly in Mediterranean Sea as one of “lighthouse” major sea basins) and promote circular, low-carbon multi-purpose use of marine and water space which is exactly what our project does by empowering the decarbonisation of maritime transportation through pilot actions, capitalisation and re-use of the results. The project will also contribute to results of this EU mission by 2030, ie. deployment of zero emission marine technologies and solutions, usage battery, hydrogen or ammonia propelled ferries calling at ports in different countries and emission reduction technological solutions for renewables, ports and infrastructure.
- Another opportunity we address with this project is the establishment of ‘Emission Control Areas’ linked with EU mission "Restore our Ocean and Waters" as aiming at zero pollution in all EU waters , spearheaded with efforts for covering the Mediterranean Sea for which the Mediterranean Sea Emission Control Area for Sulphur Oxides and Particulate Matter (Med SOx ECA) was adopted by IMO, in December 2022, with effect from 1 May 2025. In this way, our project becomes a lighthouse project for testing the ability to meet emission limitation policies in maritime transport that will apply to the Adriatic Sea.
- Other Strategy on Energy System Integration
- Powering a climate-neutral economy: An EU Strategy for Energy System Integration document recognizes that energy system integration helps to reduce greenhouse gas emissions in sectors that are more difficult to decarbonise, for instance by using renewable and low carbon fuels in maritime transport. Energy system integration also ensures a more efficient use of energy sources, reducing the amount of energy needed and related climate and environmental impacts. In certain end-uses, new fuels will be required that use significant amounts of energy to be produced, such as hydrogen or synthetic fuels. This project is in line with these goals of Strategy for Energy System Integration, especially by enabling the diversity of green fuels in maritime transportation and port services and infrastructure which enables refuelling of hydrogen needed for supplying maritime routes which need significant amounts of energy to be produced and where electrification is not efficient.
- Other REPowerEU: affordable, secure and sustainable energy for Europe
- The REPowerEU plan sets out a series of measures to rapidly reduce dependence on Russian fossil fuels and fast forward the green transition, while increasing the resilience of the EU-wide energy system. It is based on accelerating clean energy where REPowerEU will speed up the green transition and spur massive investment in renewable energy. Project results will empower this energy transition and enable speeding up the investments which will increase the demand for green hydrogen.
- Other Croatian Strategy for Hydrogen by 2050
- The project is in line with this national strategy, which recognizes maritime transport as a great potential for the use of hydrogen, especially when it comes to traffic related to connecting the mainland and islands. The implementation of the project directly contributes to the goals of increasing the demand for green hydrogen through the demonstration of its application in maritime transport.
- Other Italian National Hydrogen Strategy
- The project is in line with this national strategy, which recognizes maritime transport as a great potential for the use of hydrogen. The implementation of the project directly contributes to the goals of increasing the demand for green hydrogen through the demonstration of its application in maritime transport.
