Eligibility

The I3-4-SEAWEED – Open Call is looking for SMEs that have a participation in the seaweed value chain and present very specific needs and solutions (from production to downstream applications) supporting directly or indirectly (eg.: by completing a specific value chain and/or to offer a specific groundwork for testing and optimising products and production processes, or for the exploitation of the results of the investment cases) the I3-4-Seaweed investment cases and this create a solid ground for a successful scale-up and market entry.

Eligible applicants for the I3-4-SEAWEED – Open Call are: Legal entities or consortia of legal SME entities or consortia (up to 2) of legal SME entities.

Consortium Requirements:
Up to 2 legal SME entities. Applications with more than 2 eligible applicants will be deemed as non-eligible.
A valid VAT number is required and will be verified as part of the administrative eligibility check.
Please consult the EU SME Definition for details on what constitutes a SME.

FAQ

What is I3-4-Seaweed?

I3-4-SEAWEED Project: Investing in seaweed innovation across Europe.

Comprising 16 partner entities from 6 EU countries, I3-4-SEAWEED champions interregional collaboration aimed at scaling, demonstrating, and ensuring market readiness of business ventures within the macroalgae/seaweed sector. Combining the strengths of innovative SMEs, universities, tech hubs, and industry clusters, the project envisions a transformative, transnational value chain rooted in new sustainable seaweed cultivation techniques and algal biotechnological applications.

How does I3-4-SEAWEED work?

I3-4-SEAWEED will distribute €1.8M to 30 projects (60 000€ each) via grants to the third parties ( SMEs and scaleups) and will provide services according to their individual needs.

Where does the funding come from?

Funding is given by the I3-4-SEAWEED consortium under a Sub-Grantee Agreement signed by the selected proposers and I3-4-SEAWEED consortium. The funds are given by the European Commission (I3 Grant Programme).

What is the duration of the project?

A call will be launched to select 30 projects in the Macroalgal production & Algal Biotechnology and Downstreams applications. The selected SMEs will then have 12 months to implement their project and participate in the I3-4-SEAWEED Capacity Building Programme.

What is the deadline for the Open Call?

The 22 October 2025, 17:00 Brussels time. There will not be deadline extensions unless a major problem, caused by I3-4-SEAWEED and not by the applicants, makes the system unavailable.

Can I submit multiple proposals?

Applicants may apply to both strands (Macroalgal Production and Algal Biotechnology and Downstream Applications) in this Open Call. However, only the highest-ranked proposal, in which the entities participate, will be eligible for funding. Any other applications involving these entities, regardless of their scores, will be disqualified.

What is the Technology Readiness Level (TRL) requirement for proposals?

A: Innovative solutions proposed by eligible applicants must have a minimum TRL of 6. The aim is to facilitate demonstration and accelerate market uptake and commercialization by the end of the I3-4-SEAWEED programme.

How do I apply?

The online submission platform provided by F6S is the entry point for all proposals. Submissions received by any other channel will be automatically discarded.

Apply at F6S: 

           – Strand A : https://www.f6s.com/i3-4-seaweed-strand-a

Outermost Regions (defined in Art. 349 TFEU): List of eligible Outermost Regions.

Are Consortium eligible?

Applicants can submit their applications as either an individual organisation/ entity or as a consortium comprising a maximum of two SMEs. 

Consortia submissions must include SMEs  with a demonstrable participation in the seaweed value chain who present specific needs and solutions, spanning from production to downstream applications.

Applicants may apply to both strands  in this Open Call. However, only the highest-ranked proposal, in which the entities participate, will be eligible for funding. Any other applications involving these entities, regardless of their scores, will be disqualified.

What are the funding conditions?

Each selected application can receive a maximum grant amount of €60,000, which will represent 100% of the project costs (including indirect costs). Funds will be disbursed as lump sums in installments after the achievement of agreed milestones and deliverables in two periods. Eligible costs include staff costs for project management, research and technical development, testing and piloting activities; communication, promotion, and exploitation activities; travel (as required); and project-specific equipment. Subcontracting is permitted up to 20% of the total project budget.
