Water Electrolysis

[SahrulArsad]

Hi klei,

i just wanna ask something about water electrolysis machine

why hydrogen gas produce less than oxygen when i real life hydrogen produce more than oxygen

it so hard because hydrogen generator need a lot of hydrogen gas 

can you can it

Oxygen has a greater mass than Hydrogen, in a 2:16 ratio, or for simpler sakes 1:8 which makes the number pretty accurate.

The best thing to do is either use a Filter to filter the Hyrdogen into another room and wait till it is pretty full and have 1 pump, and 1/2 hydrogen generators (Depending on how quickly you wanna burn through the gas, if you only want the 800W then 1 Hydrogen generator will take longer to consume it all)

You can also use a mechanical filter for the same job but I have no experience using them.

A Hydrogen Generator uses 100g/s f hydrogen whilst an electrolyzer produces 118g/s IIRC if your set up is done properly then you can avoid downtime and gas destruction.

If you set up the room around an electrolyer properly, you don't even need to use a filter.
Oxygen is heavier than H2, so H2 will go up and to the left, whereas O2 will go down and to the right. So if you set up the airflow around the electrolyer to make use of this, you can have the H2 drift up and to the left into a colleciton room, where you pump it out into the generator, and use another pump along with another pump underneath the electrolyser that pumps the O2 away and throughout your base.
When setting this up, I recomend not trying to clean the H2 room of 'unwanted' O2 in there, but just have it pump into the generator directly, it will take some damage from this, but that can be repaired until the room is cleaned on it's own. If you are a neat freak, you can jus pump it out with the H2 pump and use a vent to get rid of it, until there's only H2 left in there, and then hook it up to the generator too.
Also add a valve to the pipe going into the H2 generator, to Ensure that you don't oversaturate the generator, this leads to a loss of a lot of hydrogen, which can cause a lack of it, when needed and requiring a dupe to keep the system going every now and then.
My current setup has 2 electrolysers and 4 pumps running with 2 generators hooked up, with plenty of extra power left to spare for some other stuffs.

The ratio in-game is even more precises than you suggest.

Using the standard atomic weight for O: 15.999u and H: 1.008u one arrives at a ratio of: 1 H²O = 0.8880932556203164 O + 0.1119067443796836 H, which resembles the conversion implemented in the game. Credit where credit is due.
