Periodic Reporting for period 1 - NEMOSHIP (New modular Electrical architecture and digital platforM to Optimise large battery systems on SHIPs)
Période du rapport: 2023-01-01 au 2024-06-30
Context of the project:
The new co-programmed European Partnership Zero Emission Waterborne Transport (ZEWT) aims to provide and demonstrate zero-emission solutions for all main ship types and services before 2030, which will enable zero-emission waterborne transport before 2050.
Electrification and electrical energy storage systems will be paramount, not only as a stand-alone system in full electric ships, but also as an enabler for all other technologies facilitating hybrid electric ships. Norway is today a pathfinder in decarbonising maritime applications: Equinor has reached 50% GHG emission reductions compared to 2008 from its vessels for offshore oil and gas installations by combining policy, technological and managerial actions; Corvus has provided more than 500 marine battery systems for different ships from 2018 to 2021. However, further GHG emission reductions are more complex and costly and there are still challenges to lead shipowners to invest as fast as intended in large battery systems to extend zero emission transit for both full-electric and ICE hybrid ships (retrofitted or new-designs), and this across sectors and regions in Europe.
To reach these ambitions five main challenges have been identified by the NEMOSHIP consortium:
1. Ensure the safety and knowledge of the crew during installation and exploitation of large batteries
2. Standardise installation and integration solutions within a wide range of ships and electrical grids (AC and DC)
3. Reach a competitive Total Cost of Ownership (TCO) compared to conventional fossil-based solutions
4. Improve the operational benefits of batteries while ensuring longer zero emission sailing
5. Upskill shipowners and operators in best decision making and operation
NEMOSHIP ambition is based on four major findings that, according to the consortium, are today an obstacle to address those five challenges for exploiting electrical energy storage systems and better optimising large battery electric power within fully battery electric and hybrid ships:
Objective 1: Flexible electrification solutions to exploit heterogeneous storage units for a wide range of needs
Objective 2: Standardisation of the battery systems integration process and interfaces within the vessels
Objective 3: Advanced tools for ship operators and owners to reach an optimal and safe exploitation
Objective 4: Extending zero emission ability for both hybrid and full-electric ships
To reach these goals, NEMOSHIP will:
- Develop a modular and standardised battery energy storage solution enabling to exploit heterogeneous storage units and a cloud-based digital platform enabling a data-driven optimal and safe exploitation;
- Demonstrate these innovations at TRL 7 maturity for hybrid ships and their adaptability for full-electric ships thanks to: (i) a retrofitted offshore vessel (diesel/electric propulsion once retrofitted), (ii) a newly designed hybrid cruise vessel (LNG/electric propulsion) and (iii) a semi-virtual demonstration for two additional full-electric vessels such as ferries and short-sea shipping.
All results will be built upon a treasure chest of 18 years of energy storage system operation data. Thanks a very ambitious exploitation plan, accompanied by very large dissemination actions, the NEMOSHIP consortium estimates that these innovations will reach the following impacts by 2030: electrification of about 7% of the EU fleet; generate a potential revenue of €300M thanks to the sales of the NEMOSHIP products and services; reduce EU maritime GHG emissions by 30% compared to business as usual scenario; and create at least 260 direct jobs (over 1000 indirect).

In terms of technical WPs, during this first reporting period, the consortium progressed mostly on WP1 to WP6.
WP1, which laid down a foundation for NEMOSHIP, was finalised and resulted in 5 deliverables and a journal paper. In this WP, the consortium reviewed key outcomes from high impact research and innovation projects from ZEWT and other sectors. NEMOSHIP also analysed data from installation and operation from hundreds of Battery Energy Storage Systems (BESS) on vessels. Lessons learnt from these two activities are feeding into the remaining of WP1 and the other WPs of the project. As part of WP1, partners also defined the requirements for the use cases, the modular BESS and the NEMOSHIP digital platform.
WP2 (multi-layer digital platform development and implementation) progressed signifcantly with 2 deliverables finalised and the others to be finalised by the end of the year 2024. The design specifications, architecture and test plans of the platform were defined starting from WP1 requirements and the first prototypes were created. Work on the digital twins progressed for the Ponant and Solstad use cases.
WP3 focuses on the modular BESS design, integration and testing; a deliverable has been finalised. The team defined the heterogeneous BESS sizing for the Solstad case study. Moreover an extensive testing/characterisation session took place on the batteries used within NEMOSHIP and data were useful among others to develop models for WP2.
WP4 is about the multi-level management system development. The consortium is developping the power and energy management algorithms which will be implemented in the NEMOSHIP case studies in the second part of the project.
WP5 focuses on the Solstad demonstration vessel. Detailed plans for the 1MWh BESS installation are being developed with an installation planned to be finalised in mid 2025.
WP6 is about the 4.5MWh BESS optimisation for the Ponant use case. Partners are working on the data analysis and test programme definition.

The main results achieved so far are the following:
1) An analysis of datasets from hundreds of BESS installations on vessels was carried out by the consortium and is described in a WP1 deliverable as well as a journal paper. Some of the key outcomes are summarised below:
- The total installation cost of a 4.5 MWh BESS case study was nearly 5 M€ which results in 1100 €/kWh, which is much lower than the 5400 €/kWh observed from the retrofitting of a 630 kWh BESS onto an offshore supply vessel (OSV) in 2018. It is as expected that new installations of BESS are much cheaper than retrofitting BESS onto an existing vessel. In addition, the larger the capacity of the BESS, the lower the cost per kWh it usually results in.
- The full cycle analysis showed that the systems were essentially under-used. One comparison between the actual BESS cycle vs the designed number of cycles on 19 OSV shows that the actual BESS cycles are much lower than the designed cycles planned for 16 of the OSV.
- Fuel savings per BESS kWh yearly varied over a wide range from 78 to 706kg/kWh across 10 installations. These numbers are impacted e.g. by whether the vessel had access to shore supply.

2) A methodology to size a heterogenous BESS for a vessel with high energy and high power units was developed and applied to the Solstad case study. To ensure wide uptake, we plan to disseminate it via scientific conference/paper.
