Assessment tools for scenarios in two case studies
A detailed analysis of the impacts of the value chain’s implementation will be performed by CERTH and RINA, by conducting techno-economic analysis & life cycle costing (TEA/LCC) and life cycle assessment & social life cycle assessment (LCA/S-LCA). During the first project year, they established the foundation for these evaluations by developing a robust methodology. This includes the identification of system elements and boundaries, the creation of energy and mass models, the assessment of data requirements, and the definition of key performance indicators.
This work was supported by AUTH which defined multiple scenarios for POSEIDON’s two case studies, the port of Valencia and Thessaloniki, which will serve as input data for TEA/LCC and LCA/S-LCA. Initial drafts of the scenarios were presented to the project partners in October 2024, and were finalised in February 2025 after feedback was received from members of the COP in Valencia and Thessaloniki.
Looking forward
Following this milestone, partners CERTH and RINA have further developed their assessment tools to make them compatible with the scenarios under investigation. In September 2025, CERTH presented preliminary results of the TEA for the first scenario of the Thessaloniki case study. In the coming months, CERTH and RINA will conduct in-depth assessments of the various scenarios. The results of these analyses will be crucial for identifying the most promising scenario for each case study and developing roadmaps outlining implementation steps for new e-methanol value chains for shipping in Valencia and Thessaloniki.
