💰 Funding Details

Funding Description

Call identifier: HORIZON-CL5-2025-04-D5-10

Type of action: Horizon Europe Innovation Action (IA) – single-stage

Indicative EU contribution per grant: up to €22.5 million (70 % of eligible direct costs for for-profit entities; 100 % for non-profit entities + 25 % flat-rate indirect costs)

Total topic budget (WP 2025): ~€45 million (expected to fund ONE project in Area A *or* ONE project in Area B, or ONE in each area if two high-quality proposals are retained)


What is funded

* Design, construction and full-scale demonstration of a low/zero-carbon propulsion system on a >5 000 GT vessel:

* Area A: ≥ 5 MW combined fuel-cell (FC) power running exclusively on low/zero-carbon fuels.

* Area B: ≥ 10 MW combined internal-combustion engine (ICE) power with ≥ 85 % low/zero-carbon fuels.

* On-board fuel storage & handling innovations, bunkering interfaces, pilot-fuel minimisation, emission-after-treatment.

* Safety, risk & standardisation packages – quantitative risk assessments, protocols for ports, bunkering distances, dispersion modelling, PPE definition.

* Knowledge repositories, software tools for optimised integration, data generation for future standards.

* Replication studies: three virtual/on-site case studies on other ship types using hardware-in-the-loop & digital twins.

* Training & up-/re-skilling modules for seafarers, port workers, classification societies.

* Exploitation & business planning including Innovation Fund/CEF-AFIF pathways, EU strategic autonomy proof, IP management.


Eligibility snapshot

* Consortium: Minimum 3 independent legal entities from 3 different EU Member States or Horizon Europe Associated Countries.

* Strong involvement of:

* EU/EEA shipyard where the demonstrator retrofit/build is executed.

* Equipment manufacturers of FC/ICE, fuel storage, safety systems.

* Ship owner/operator (commercial or public) providing the ≥ 5 000 GT vessel.

* Port/terminal authority hosting bunkering & safety tests.

* Non-EU entities may participate if bringing essential know-how and if they fund their own costs (unless their country has made funding available).

* Ineligible cost category: any cost linked to CCS/CCUS equipment.


Key funding rules

1. Single grant agreement per proposal; pre-financing ~40 % of EU contribution.

2. Project duration: typically 48–60 months (must align with full-scale sea trials + replication studies).

3. Technology Readiness Level (TRL) at start: 5–6 ➜ TRL 7–8 at project end.

4. Open Science: mandatory Data Management Plan; results to feed ZEWT Partnership KPIs.

5. Security scrutiny: compliance with European Economic Security Strategy—IP & data mainly located/controlled in EU/EEA.

🇪🇺 Strategic Advantages

EU-Wide Advantages & Opportunities for HORIZON-CL5-2025-04-D5-10


1. Single Market Access – 450 + Million Consumers

• Deploying a 5 MW (FC) or 10 MW (ICE) zero-carbon propulsion demonstrator under an EU programme gives automatic visibility and credibility across all 27 Member States, Iceland & Norway.

• Early movers can commercialise retrofit and new-build packages for the 23 000 EU-flagged vessels and the 90+ deep-sea ports that must comply with FuelEU Maritime as of 2025.

• Common technical specifications arising from the project’s “knowledge repository” shorten time-to-market for equipment sales, service contracts and digital twins across the Union.


2. Cross-Border Collaboration & Knowledge Exchange

• Horizon Europe consortia typically gather 8-20 partners from ≥3 countries, enabling:

• Shipyards (e.g. Italy, Spain, Croatia), engine makers (e.g. Finland, Germany), and fuel suppliers (e.g. Denmark, Netherlands) to co-design integrated systems.

• Joint safety drills with port authorities in North Sea, Baltic and Mediterranean hubs, creating transferrable SOPs.

• Mobility schemes (Marie-Skłodowska Curie, ERASMUS+) can be pig-backed for crew upskilling, while ERANet Cofund projects offer test-bed data.


3. EU Policy Alignment – A Shortcut to Market Uptake

• Green Deal, Fit-for-55, FuelEU Maritime, and the 2023 IMO GHG Strategy are directly referenced in the call; meeting these regulations early eases certification in all coastal Member States.

• The project advances ZEWT Partnership KPI of “75 % decarbonisation of EU waterborne transport by 2050,” therefore enjoys political backing and streamlined dissemination via the Partnership platform.

• Alignment with the European Economic Security Strategy increases chances for IP retention in Europe and eligibility for national recovery & resilience plans (RRF) co-funding.


4. Regulatory Harmonisation & Standardisation Leadership

• Producing EU-level safety protocols for ammonia, methanol, hydrogen and e-fuels feeds directly into CEN/CENELEC and IMO rule-making.

• Early involvement of EMSA, CESNI and port authorities allows partners to shape unified bunkering rules, reducing compliance costs vs. fragmented national approaches.


5. Access to Europe’s Innovation Ecosystem

• Synergies with JRC labs, EU Digital Innovation Hubs, and testing facilities (e.g., MARIN, HSVA) accelerate virtual prototyping & hardware-in-the-loop trials requested by the topic.

• Europe hosts >60 fuel-cell pilot lines and >40 specialised maritime clusters; the grant acts as a magnet for these actors via open data mandates and replication studies.

• Participation unlocks EOSC (European Open Science Cloud) resources for big-data analytics on vessel performance.


6. Funding Synergies & Blended Finance

• Demonstration CAPEX can be followed by:

• Innovation Fund large-scale window (up to 60 % OPEX coverage) for first-of-a-kind commercial vessels.

• CEF-AFIF calls for complementary bunkering infrastructure at participating ports.

• EIB Green Shipping Guarantee 2.0 for debt financing of fleet roll-out.

• InvestEU & BlueInvest equity for scale-ups supplying storage tanks, FC stacks or digital twins.

• National “Important Projects of Common European Interest” (IPCEI) on hydrogen can co-finance the fuel supply chain created in the project.


7. EU-Scale Deployment, Replicability & Impact

• Mandatory three replication studies ensure adaptability to ferries, cruise ships and Ro-Ro vessels operating in distinct EU sea basins, facilitating pan-European uptake.

• Meeting the call’s 55 % tank-to-shaft efficiency target and 90 % pollutant reduction generates >7 Mt CO₂-eq annual savings if deployed on only 10 % of EU deep-sea fleet.

• Certified training modules developed under the grant can be adopted by 750+ maritime academies in the European Maritime Education Platform (EMEP), solving crew-skill shortages EU-wide.


8. Strategic Value Beyond National Programmes

• Consolidates EU technological autonomy by favouring EU/EEA shipyards and suppliers, reducing reliance on Asian engine retrofits.

• Creates a first-mover barrier for non-EU competitors through IP generated under Horizon Europe’s fair-access rules.

• Boosts regional cohesion: Baltic Sea countries gain green-corridor solutions, while Mediterranean yards access high-power FC know-how.


9. Actionable Next Steps for Applicants

1. Build a triad core: (i) OEM propulsion leader, (ii) EU shipyard with >5 000 GT orderbook, (iii) Tier-1 port authority.

2. Map complementary EU instruments (Innovation Fund, CEF-AFIF, EIB) in the Part B “continuation strategy.”

3. Engage CEN/CENELEC TC 400 and IMO MSC via early Stakeholder Advisory Board to maximise standardisation influence.

4. Leverage Copernicus Marine data & EMSA THETIS MRV database for life-cycle emissions baselining.

5. Pre-align crew training content with European Maritime Safety Agency’s STCW conventions to expedite certification.


Bottom line: Competing in this Horizon Innovation Action unlocks unmatched cross-border resources, regulatory influence and financing pathways that no single Member State scheme can offer—positioning the consortium to set the de-facto EU (and potentially global) benchmark for high-power zero-carbon propulsion in waterborne transport.
