Mechanical propulsion has been the mainstay of nuclear submarines for some 50 years, the power historically provided by two steam turbines driving into a fixed-train gearbox with a common single-shaft output. Electrical loads are met by twin steam turbo-generators. The overall configuration is illustrated in Fig. 2.

Krummrich and Llabrés [18] noted that almost all FC submarines built to date rely on hydrogen storage in metal hydride storage cylinders.

Although technically similar to the starter-batteries in autos, modern submarine battery rooms are complex installations. They have to be. Batteries are at the heart of submarines in several ways. They keep the vessel alive, purify the air, power the motors, turn the propellers, and empty the flotation tanks so it can surface. Related

Energy Storage System Integration: Submarines often employ energy storage systems, such as batteries or supercapacitors, to store excess electrical energy and provide power during peak demands.

Several conclusions can be drawn as follows: The designed endurance of the submarine is limited by the weight of AIP system. The maximum designed endurance is. 26 days for fuel cell using liquid hydrogen and liquid oxy- gen, and the minimum designed endurance is 10 days for using metal hydride and compressed oxygen.

Irish inventor John Philip Holland designed the Holland Type VI submarine in 1897. It made use of a 45-horsepower internal combustion gasoline engine for power on the surface and a 50-horsepower electric motor and a 66-cell Exide battery for propulsion when submerged. The batteries gave a 35-mile range at 6.3 mph while submerged.
