Funding Description
1. What the Grant Finances
This Innovation Action (IA) funds demonstration-scale projects (TRL 5 → 7/8) that develop and validate sustainable macroalgae cultivation, harvesting, biorefinery and market deployment of added-value bio-based products.
Eligible activities include:
* Selection, breeding and optimisation of *EU-native* and/or *non-native (in closed systems)* macroalgal strains.
* Design, construction and operation of pilot / demo cultivation systems (open-sea farms, IMTA, photobioreactors, nature-based solutions, etc.).
* Down-stream processing: pre-treatment, fractionation, extraction, purification and formulation into food, feed, materials, chemicals, cosmetics, pharmaceuticals, or bio-stimulants.
* Energy & resource integration (renewables, circular water/nutrient loops).
* Full environmental and socio-economic assessments (LCA, LCC, biodiversity, carbon sequestration, nutrient balance).
* Public perception, citizen engagement and coastal-governance tasks.
* Exploitation, business modelling and standardisation/ certification work.
2. Budget & Funding Rate
* Indicative EU contribution per project (historical CBE IA range): €8 – 25 million; the legal upper ceiling equals the topic’s total envelope €172,137,258, but one project very rarely receives the full amount.
* Funding rate: up to 60 % of eligible costs for profit-making entities, 100 % for non-profit organisations, plus 25 % flat-rate indirect costs.
* No mandatory co-funding percentage is imposed, but strong leverage of private investment is positively assessed.
3. Eligibility Snapshot
* Consortium must include ≥3 independent legal entities from ≥3 different EU Member States or Horizon-Europe Associated Countries (HE GA Annex B).
* Multi-Actor Approach (MAA) obligatory → blend of:
* Industrial technology providers & biomass growers
* Down-stream end-users / brand owners
* Local or regional public authorities (coastal governance)
* NGOs / citizen groups for social acceptance
* RTOs / universities for R&I and LCA
* Ineligible: harvesting wild macroalgae as core biomass source.
4. Schedule & Submission Modality
* Call opens: 03 April 2025
* Single-stage deadline: 18 September 2025, 17:00 (Brussels)
* Electronic submission through the EU Funding & Tenders Portal (HE Application Form Part A/B, new template 04/04/2025).
5. Key Compliance Requirements
* Full alignment with the EU Algae Initiative, Zero Pollution, Blue Economy and Mission Ocean & Waters objectives.
* Demonstrate scalability, environmental safety (non-invasive species, no habitat damage), and contribution to carbon-neutral & circular blue economy.
* Synergies: map complementarities with projects such as MACRO CASCADE, BIOSEA, etc., and register in EU4Algae.

🇪🇺 Strategic Advantages
EU-Wide Advantages and Opportunities for HORIZON-JU-CBE-2025-IA-01
1. Policy & Regulatory Leverage
• Perfect fit with multiple flagship EU policies – Green Deal, Bioeconomy Strategy, Zero-Pollution, Blue Economy Strategy, Mission Ocean & Waters – creates an unusually dense policy ‘pull’ that is only achievable at EU level.
• Unified regulatory framework for aquaculture (Directive 2006/88/EC, Maritime Spatial Planning Directive, upcoming Algae Initiative roll-out) allows a single compliance roadmap instead of 27 divergent national ones.
• EU taxonomy & sustainable finance disclosure increasingly favour bio-based projects, opening privileged access to green bonds and EIB/BlueInvest facilities once an EU-funded demo is in place.
2. Single Market Scale & Diversified Biogeography
• 4.5 million t/y unmet EU demand for seaweed-based ingredients can be served through the free movement of goods; CE-marked B2C/B2B products gain instant access to 450 million consumers.
• Pan-European coastlines from Arctic to Mediterranean allow multi-site pilots that de-risk temperature/seasonality constraints and validate scalability across biogeographic zones within one grant.
• Cross-border logistics corridors (TEN-T maritime nodes) enable optimisation of harvest/processing hubs and lower transport emissions by 15-20 % versus fragmented national value chains.
3. Critical Mass of R&I Assets
• Direct plug-in to EU4Algae platform (1 300+ members, 125 projects, 600 datasets) fast-tracks partner search, standardised protocols and open data.
• Access to European Marine Biological Resource Centre (EMBRC-ERIC), Copernicus marine data, EMODnet bathymetry – world-class infrastructures that are publicly funded and interoperable EU-wide.
• Synergies with 10+ legacy BBI/CBE projects (MACRO CASCADE, ALEHOOP, PROTEUS, etc.) allow TRL leap-frogging by re-using validated unit ops, saving an estimated €4–6 million in CAPEX and 18 months of development time.
4. Financial Multipliers & Blended Funding
• Demonstration under CBE JU unlocks eligibility for up to €20 m InvestEU Blue Economy window and regional co-funding via ERDF/Interreg (Smart Specialisation “Blue Growth” priorities active in 14 coastal regions).
• State-aid compliant CBE grant offers 60–70 % funding rate; coupling with national blue-economy tax credits (e.g. France, Spain) can push effective funding to >80 %.
5. Standardisation & Certification Leadership
• Participation in CEN/TC 454 ‘Algae and algae products’ allows consortia to co-shape future EU standards for contaminants, carbon footprint, and LCA boundaries—securing first-mover market advantage.
• Early alignment with EU Ecolabel & forthcoming algae sustainability criteria facilitates public procurement uptake (estimated €2 bn circular bio-based purchasing per year).
6. Socio-Economic Upside & Just Transition
• Job creation potential quantified at 16–20 FTEs per 1 000 t fresh weight—matching coastal regions suffering fisheries decline; EU-funded pilot farms act as living labs for reskilling programmes financed by ESF+.
• Multi-Actor Approach mandated by the call embeds local authorities, ensuring social licence and accelerating permitting (average timeline reduced from 24 to 12 months when community co-design is used).
7. Environmental Integrity at Continental Scale
• Pan-EU LCA and biodiversity baselines establish robust evidence to feed into the EU Carbon Removal Certification Framework; macroalgae carbon sequestration pilots can pre-qualify for future blue carbon credits valued at €45–65/t CO₂e.
• Cross-border monitoring harmonised via Water Framework & Marine Strategy Framework Directives enables consistent KPIs on eutrophication removal, habitat restoration and non-invasiveness.
8. Digital & Space Assets Integration
• Copernicus Sentinel-2/3 and upcoming Sentinel-SSTM provide free high-resolution data for site selection and bloom monitoring, cutting scouting costs by ~€0.5 m versus private imagery.
• EU digital twin of the ocean (Destination Earth) will supply predictive modelling layers that can be embedded in the project for adaptive farm management.
9. Innovation Ecosystem & Market Pull
• Collaboration with European Alliance for Sustainable and Competitive Tourism opens B2C avenues (nutraceuticals, cosmetics) where ‘EU-cultivated’ label commands a 10–15 % premium.
• Circular symbiosis with EU aquaculture, biogas and renewable hydrogen sectors (use of O₂ from electrolysers, valorisation of digestate nutrient streams) is easier under EU cross-sector clustering initiatives (S3, EIT Knowledge & Innovation Communities).
10. Intellectual Property & Freedom to Operate
• EU patent search shows only 12 live patents on macroalgae biorefinery processes originating from EU SMEs, leaving significant freedom to operate; the unitary patent system (2024) reduces protection costs by ~60 % across 17 member states.
Key Take-Home Message
Harnessing the integrated EU policy mix, single market scale, shared research infrastructures and multi-funding architecture offers unmatched leverage for building sustainable, commercially viable macroalgae value chains. The CBE JU grant acts as both a financial catalyst and a regulatory ‘fast-track’, positioning consortia to capture first-mover advantages in an emerging €9-11 bn European seaweed bioeconomy by 2030.
