With the third stakeholder-workshop successfully organised on 26 January in Vienna, an important step forward has been made in further fine-tuning and developing a strategic roadmap for the implementation of hydrogen infrastructure along the Danube. Funded by the Austrian Research Promotion Agency (FFG), the aim of the exploratory project H2 meets H2O is to assess the feasibility and applicability of hydrogen supply along the Danube as logistics backbone from a technical, legal and socio-economic point of view. Pro Danube, in its capacity as project coordinator, provides input to the roadmap from a twofold perspective: on the one hand by reflecting the industry's perspective and on the other hand by investigating the multitude of financing and funding possibilities on the EU level for potential follow-up projects.
