The scope of this DMP is to outline the framework followed for the management of the data in NextFuel. It provides details about the creation, storage, maintenance, archiving and long-time preservation of all the project related data. The project includes various types of data, ranging from technical specifications and design documents to financial models, environmental impact assessments, safety protocols and more. This DMP describes actions to protect sensitive or proprietary information and addresses procedures for secure storage, backup, and access control. Also, it ensures that data will be FAIR (findable, accessible, interoperable and reusable) as per Horizon Europe guidelines. The DMP was created in accordance with the Argos OpenAIRE format.
