Enrolment call of the EOSC Tripartite Governance
This call invites organisations to join the second wave of the EOSC Federation’s build-up phase, requiring them to enrol as an EOSC Node, submit a Project Charter, develop use cases, and demonstrate their capacity to function as a community gateway.
Total funding: No funding is provided through this call
Maximum grant amount: Not applicable
Preparatory grants under EOSC Gravity
These grants are designed to support the preparatory work of potential future EOSC Nodes. The main objective is to develop a Project Charter for a subsequent, separate application to the Enrolment Call of the EOSC Tripartite Governance.
Total funding: €800,000
Maximum grant amount: €50,000 per project

Inter-project grants under EOSC Gravity
This call aims to expand the services offered through the EOSC Federation and to demonstrate the benefits for end users. This can be achieved in two ways: by developing scientific use cases, or by piloting the onboarding of new services into existing EOSC Nodes, without the requirement to become an EOSC Node at this stage.
Total funding: €400,000
Maximum grant amount: €50,000 per project

A second inter-project grants call, with a separate budget, will be launched next year
