Question

How do submarines dispose of the hydrogen when they produce oxygen by electrolysis of water?

Answer 1

Norrie,

Research before you speak!

The H2 produced by the Advanced Electrolic Oxygen Generator (AEOG for short) is immediatley discharged overboard. Having H2 on a submarine is not a good thing.

The H2 Burners, get rid of residual H2 in the atmosphere mainly caused by the battery, not to get rid of the H2 from the AEOG.

The DI water comes from either the Evaporator, Still or Reverse Osmosis destiller (This makes fresh water) it is than De-Ionized through a seperate filter for DI water to be used in the Reactor, Battery Cells, and AEOG.

Answer 2

H2 Burners

Answer 3

Its vented to the sea via a diffuser to minimize noise and bubble size.
