The overall objective of the PROTEO project is to develop and validate an efficient, modular and scalable naval platform for ferry-type vessels. The proposal is based on three pillars: the integration of electric propulsion systems, the use of advanced hydrofoils manufactured from sustainable materials, and the intelligent monitoring and prediction of wave conditions. It also involves the design and integration of port-based electricity supply solutions, with the aim of improving energy efficiency, reducing emissions and enhancing stability and operational reliability in maritime and port environments.

The Fundación Valenciaport contributes its knowledge of the port environment and real-world operating conditions to ensure the applicability of the power supply solutions within existing infrastructure. Under this approach, the technical requirements for the charging infrastructure (voltage, current, power and energy) will be defined according to the different vessel sizes and the port call times available. Once this characterisation has been completed, the various alternatives for integration into both the port’s electricity grid and the future medium-voltage ship power supply infrastructure (OPS) will be assessed.

Furthermore, the Fundación Valenciaport will assess the required investments, operational and maintenance costs, and the minimum revenue needed to ensure a positive return on investment over the facility’s useful life. This financial analysis will be applied to the use case for the battery-charging infrastructure at the port. Based on these results, the associated business model will be designed and scalability solutions tailored to the different vessel sizes under consideration will be proposed.
