Lessons Learnt from High Impact R&D Projects from ZEWT and Other Sectors with ESS

The objective of this paper is to cluster the main challenges and gaps for the safe integration of batteries in vessels, and for the improvement of the operation and performance of energy storage in the maritime sector. To do this, a benchmarking methodology was developed that compares technical and non-technical topics relevant to the identification and classification of EU-funded R&D projects with NEMOSHIP project. Firstly, the most relevant projects were selected considering the main topics of NEMOSHIP and their relationship with waterborne, electromobility, stationary or energy storage applications in general. Secondly, a weighting criterion is established for each project by evaluating the information available for each topic. In addition, the different technological trends, decisions, and roadmaps established in the most relevant and selected projects of the methodology are analysed. Finally, general conclusions and a compilation of lessons learned are presented from both a technical and non-technical perspective.
