SOERMAR will present four European projects in Navalia with a common objective, the decarbonization of waterborne transport

The projects seek the decarbonization of waterborne transport through the development of new battery systems, their control systems and hyperchargers in port.

SOERMAR (Sociedad para el Estudio de los Recursos Marítimos) will present at the Navalia technical conferences the European projects in which it participates, SEABAT, HYPOBAT, FLEXSHIP and AENEAS, which have the common objective of contributing to make maritime transport climate neutral through the development of energy storage systems and next-generation hyperchargers.

The SEABAT project will develop a full-electric marine hybrid concept based on (1) the combination of modular high-energy batteries and high-power batteries, (2) novel converter concepts and (3) production technology solutions derived from the automotive sector. A modular approach will reduce component costs (battery, converter) so unique vessel designs can benefit from economies of scale, through the use of standardized low-cost modular components.

The outcome of SEABAT will be a validated hybrid battery solution for capacities of 1 MWh and beyond, as well as a strategy towards standardization for application to ferries and short sea shipping. The solution will offer 35% to 50% lower cost of ownership (TCO) than conventional marine battery systems, including 15% to 30% lower CAPEX investment, 50% lower costs of integration in the shipyard and a recovery of the investment cost of 5% after the end of its useful life on the vessel.

Another project is HYPOBATT, which focuses on the development of an interoperable charging solution with cost-competitive performance by improving component standardization. This project will develop a modular, fast and simple multi-MW charging system, demonstrated in two European ports with fast response times. The modular approach will minimize the required connection time, loading time and the number of components and costs. The charging system will be designed to achieve interoperability and compatibility with different electric propulsion vessels. Additionally, HYPOBATT will address the flexibility of power levels and minimize impacts on power grid infrastructure and battery degradation during fast charging. HYPOBATT unites key players in the European maritime sector to develop and demonstrate the feasibility of the hyper cargo system. This aims to develop business mechanisms to exploit the flexibility of the system between shipbuilders, integrators, ports and interested parties. This will enable wide adoption of the solution, thus increasing Europe's leadership in fast charging systems.

The AENEAS project will provide solutions to improve overall energy efficiency and drastically reduce the energy consumption of ships destined for maritime transport, developing three innovative Energy Storage Solutions (ESS), which go beyond traditional battery systems:

  • Solid State Batteries (SSB) for Constant Charge Water Transportation Applications.
  • Supercapacitors (SC) for water transport applications to reduce peak power demand and peaks during charging.
  • Hybrid system, combining SSB and SC for water transportation applications requiring high power and energy density energy storage solutions.

As for FLEXSHIP, it will develop and validate safe, reliable, flexible, modular and scalable solutions for the electrification of the waterborne transport sector. This includes the reliable design and development of modular battery packs; safe integration on board, including the battery system and its associated electrical distribution network, into the vessel's existing electrical network; optimal energy management system (EMS) design to maximize operational flexibility and energy efficiency (both all-electric and hybrid), and intelligent control through a digital twin to improve the life of the battery system and power components. critical energy. The project will test the complete system in two demonstrations and evaluate its exploitation potential.
