Periodic Reporting for period 1 - POSEIDON (POwer StoragE In D OceaN)

Reporting period: 2023-01-01 to 2024-06-30

Summary of the context and overall objectives of the project

The POSEIDON main objective is to demonstrate the applicability of 3 innovative fast-response ESS in waterborne transport addressing their on-board integration, cost-competitiveness, efficiency and safety, in relevant environments.
Then, to bottom-up from low TRL of these existing innovations ESS for waterborne transport to achieve the main objective, the following Specific Objective (SO) were defined:
SO1. To build 3 innovative marinized ESS (SMES, Supercapacitors, and Flywheel), with power capacities ranging 20-200 kW.
SO2. To demonstrate 200 hours of operation in a maritime environment of a containerized system including the 3 developed ESS systems.
SO3. To establish a refined metrics Levelized Cost of Storage (LCOS) tool for cost assessment and comparison of ESS for different waterborne segments.
SO4. To elaborate a complete lifecycle analysis of the 3 developed ESS.
SO5. To analyse potential integration with other disruptive technologies, such as hydrogen, rigid sails, and reversible hydrokinetic generators.
SO 6. To identify safety issues, potential long-term risks and to regulatory gaps as well as to propose new pre-standardization and pre-regulation for the 3 ESS.

The technological development of the project is divided in 3 blocks:

Block A: Marinization and technical development.
This block will be focused on the technological development of the project, which will be divided in 3 phases:
1) Profound analysis of the electrical grid characteristics and load profiles of different marine vessels, with special dedication to two use cases (novel electric ferry and IWT vessel).
2) ESS and ship engineering experts will build, marinize, and test the 3 ESS.
3) The 3 ESS will be put inside a container and will be tested on BALEARIA electric ferry while in operation.

Block B: Sustainability and technical feasibility.
This block will be focused on evaluating the adequacy of FRESS for waterborne applications and evaluating their environmental impact to improve energy efficiency and make waterborne transport climate neutral.

Block C: Safety and regulatory evaluation.
This block will be focused on evaluating the safety requirements and the regulatory aspects of FRESS as well as the skills requirements.

These blocks developed in POSEIDON are aligned, both in advancing technologically development of innovative EES in water transport applications, and in obtaining results that contribute to the expected outcomes of the Topic “Innovative energy storage systems on-board vessels” and, on the whole, to related long-term impacts in Destination “Clean and competitive solutions for all transport modes” towards a Zero Emission Waterborne Transport world.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

In this initial period, the project focused on developing the three main technologies under consideration. This task remains in the research and development phase. Additionally, the team has begun defining the use case. Below is a summary of the work carried out so far.
In WP2, the team completed the electromagnetic and mechanical design of the SMES as planned. Some prototypes have already been tested, and manufacturing of the final SMES has begun, starting with the first coil. The cryogenic system and power converter were selected. Laboratory testing is ongoing with early prototypes and other components of the final assembly.
In WP3, the mechanical and electrical design of the KESS was completed. However, defining the flywheel material faced delays due to slippage issues between the rotor and flywheel neck. After resolving these issues, the manufacture of parts began.
In WP4, the focus was on the design stage. The team first built a simulation model to replicate the machine’s behavior. Once the model proved effective, component selection began, with particular challenges in sizing the supercapacitors’ storage bank due to the lack of certified marine-environment modules. After thorough consideration, a suitable supercapacitor module was identified.
In WP5, the project focused on defining use cases, technical specifications, and the equipment to be installed on board. Various simulations, particularly thermal models for air conditioning sizing and heat dissipation of the ceramic disk, were conducted.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

At this stage of the project the three main technologies under development are still in the research and development phase. Given the complexity and innovative nature of these technologies, it is premature to provide definitive results beyond the state of the art. However, we can outline the expected outcomes of these technologies might have once fully developed.
