## EOSC EU Node — 50 GB personal + 500 GB group file storage per user, free credits from the European Commission

- url https://open-science-cloud.ec.europa.eu/about/access-policy
- free tier: Access-policy table: File Storage (Personal) = 50 GB for Collaborator and Investigator; File Storage (Group) = 500 GB for Investigator only. Investigator also gets 'File Transfer 1TB/month'. Credits: Collaborator 1,000; Investigator '2,000 (individual) / 6,000 (group)', renewed automatically every three months and explicitly not top-up-able. | unit: GB | metered on: stored-bytes | read on: 2026-10-21 | source: [1]
- per-object cap: not stated | source: [1] | note: not stated
- retention: Retention: credits 'cannot be transferred to another person or carried over between periods' and are 'automatically renewed every three months'; services are ordered for a fixed period and refunded pro rata if released, so nothing here is permanent | source: [1] | note: not stated
- egress: Not metered; the node is EC-procured infrastructure. The binding constraint is the monthly 1 TB transfer allowance, which is the only hard number in the policy. | metered: yes
- identity: institution
- interface: s3, rest
- limits note: per-object-cap: not stated. request-rate: 1 TB/month File Transfer is the sharpest published cap. Retention: credits 'cannot be transferred to another person or carried over between periods' and are 'automatically renewed every three months'; services are ordered for a fixed period and refunded pro rata if released, so nothing here is permanent. Gate: eduGAIN/ORCID/EU Login identity; access group is assigned automatically from your home organisation's affiliation data, and 'The EOSC EU Node does not support automatic transition between access groups.'
- interface detail: rest
- tooling: EOSC EU Node User Space web UI plus credit-metered service orders; no documented S3 endpoint. Treat as API-less until probed by an account holder.
- composes with: The chaining hook is wallets, not accounts: 'When you create a group, a separate Group Wallet will automatically be generated. This wallet is independent of your personal wallet and comes pre-allocated with additional credits.' Investigator groups also carry the 500 GB group file storage. Many groups = many 500 GB pools, and the group storage is separate from the 50 GB personal pool.
- reliability: Credits are not top-up-able ('additional ones will not be provided to you') and do not carry over — a storage-heavy month silently stops you until the next quarter.
- notes: the same as the free tier
- extras:
  - dead_end.failure_class: quota
