Maritime battery applications come in many forms and sizes, all have the common theme of the marine environment. A high level overview of the fuels and systems being used and considered for marine applications is given in the Faraday Insights [1] and the different fuel, battery and motor arrangements are covered in our overview of the systems.
Needs review: The topics list below (Battery System Design, Battery Replacement, Battery Space and Storage, Ventilation, Cooling Systems, Operation and Handling, Fire Detection and Fire Fighting) is currently a bare list of headings carried over from an outline and has not been written up. Each needs its own explanatory content (or a link to a dedicated page, if one exists) rather than being left as an unexplained checklist.

Hybrid System Type
A high level definition of the hybrid system type. The pros and cons and a look at the battery.
The mechanical output could be to the wheels of a vehicle, the propeller of a boat or aircraft. The requirements for each system will influence the sizing of the system and the balance between battery storage capacity and onboard fuel storage. Thus changing the pros and cons of each system to some extent.
The topics that need to be covered include [2]:
- Battery System Design
- Battery Replacement
- Battery Management System
- Battery Space and Storage
- Ventilation
- Cooling Systems
- Operation and Handling
- Fire Detection and Fire Fighting
- Disassembly and Recycling – see Recycling Companies
