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