is it possible to save the gases?

Question

Is it possible to save the gasess given off by a bank of lead acid batteries?

Answer 1

The offgases from lead acid battery banks consist of hydrogen as main constituent and are hazardous beyond a low concentration limit . Present practice is to design battery rooms well ventilated to vent the offgases to outside air, instead of saving them as byproduct . The amount of off gases are generally small and saving is not economic though it is possible to save them by gas separation technic . Main purpose of battery banks are to act as reliable source of power for emergency .

Answer 2

Yes, but separating them might be a problem.
