Plan and progress

Sub Project 2 - Hybrid propulsion

Marine Hybrid propulsion and batteries


The interest in using batteries in maritime applications has grown rapidly the latest years, mainly due to the success in road transport (private cars). Today hybrid propulsion systems and pure electric propulsion systems have been put in operation on several ship concepts. To increase knowledge about the utilization of such systems a study to determine the applicability for maritime use of batteries will be carried out. This will also include a full economic and environmental due diligence of such systems.

The Hybrid technologies to be focused will include: battery storage of energy to take peak power requirements, engine power arrangements, cold ironing in port by vessel batteries, propulsion at sea by electricity from batteries only and power management systems. 


Identify and quantify the potential for reduction of cost and emissions in a maritime setting. And further establish objective knowledge regarding technology potential for battery capacity, lifetime and cost

Prerequisites and limitations

Input from industry partners is requied to get good results. This is especially relevant for component data which will be used to understand system efficiency potential and as input to simulation models.


1. Battery technology – a technology review, possibilities and promises
2. Marine hybrid power systems – a technology review, possibilities and promises
3. Pure electrical marine propulsion – possible operating profile
4. Marine propulsion configurations using hybrid technologies
5. Potential of using power from batteries in harbour operations
6. Perform a full economic and environmental due diligence of battery applications.

Januar - December 2016


Deliverables 2016:
- Report on Marine hybrid power systems and components
- Simulator of the hybrid power lab, used to estimate efficiency of the equipment for different operational points


The sub-project was finalized in 2016 and the Gymir simulation tool was further developed and tested through business cases in a new Sub-project SP7, integrating the results of 2016- sub-projects SP2, SP3 and SP4.
