This document presents the first version of Deliverable D9.2 “Data Management Plan” developed as part of WP9 of the Clean Hydrogen JU HySelect project. It outlines the Data Management Plan (DMP) for the data to be generated and used as part of the project. This version of the DMP, which is prepared at the beginning of the project, serves as the basis for defining the processes that will be followed by each partner with respect to data management, as well as for designing the data management strategy at the project level. The DMP will be updated throughout the project to reflect the data generated and the uses identified by the consortium.
