Hydrogen rampant on my base twice

[minespatch]

My current problem is hydrogen flooding my base. I figured out how to recycle water with the sieve but now hydrogen is making it hard for my dupes to breathe. What would be a course of action to neutralize the situation?

[KittenIsAGeek]

The quick solution? Dig up.  Hydrogen rises.

A longer-term solution would be to put a gas pump up in the hydrogen somewhere and send it to a hydrogen generator or a reservoir (or both!)

[minespatch]

That makes sense. I'm currently trying to get oil before making my plastic rig, but I'll make a second group to start making ladders upward as well.

or if you have steady supply of oxygen to pressurize the base, you could build an attic for the hydrogen to stay and maybe chill, then maybe add a cot or two and an automated door, just in case if you need to put certain dupe to "sleep".

I guess that's where wheezewort comes in.

My tips for early base building:

Dig up to  remove hydrogen from the living area, dig down to remove CO2, Chlorine, liquids, etc.
Try to make a triangle shape ceiling to make easy to collect it later. Do the same to the bottom of the base.  My base ceiling barely touches the space biome, the floor where the oil biome start. 

Make sure the base is hermetically closed.

Before there is too much hydrogen or CO2, install a gas pump on the ceiling to collect hydrogen , and a gas pump in the bottom to pump any gas that is not oxygen to outside the base. I just burn hydrogen and dump the heavy gases to the oil biome.

I second all of that. Although you do not need to dig that deep or high initially, be prepared to extend the gas collector areas. Hydrogen you can usually just burn, with perhaps a few gas-tanks to store some for special use.

This is also one of the reasons many people do not take flatulent dupes: Then you need an additional filter and potentially pump to keep the base clear. They contaminate other areas, for example Chlorine storage, as well.

I forget to say, when the base hits the desirable size, use automation to enable or disable top/bottom gas pumps  - for the bottom is just an gaseous element set to oxygen placed 3 ou 4 tiles above the pump, a not port and a filter gate. All gas are dumped directly to oil biome. 
I install an element filter to send chlorine to the kitchen, but after there is sufficient chlorine there is no need for that.

For the ceiling i use automation keep hydrogen using an maximum/minimum system, this way i do not need to place filters. 

Base pressure is maintained automatically by the electrolizers - because hydrogen rises naturally, there is no need for SPOM or any other complicated setups - just place electrolyzer in any place and is ok. Just remember to build a liquid cooling system ready before heat becomes a big problem.

I think the first thing to ask would be "where is the h2 coming from?"

Are you running open air electrolyzers, did you dig into other biomes without sealing your living area first?  

Except with certain bugs (that I think have been fixed), h2 doesn't just show up in your base. 

[greggbert]

Try putting your electrolyzers in a vertical rectangle airtight room, preferably in the cold biome (with metal walls) with one pump at the top of the room and one or two at the bottom.  The top pump has a filter to direct hydrogen to some tanks and/or a generator, with the rest of the gas (presumably oxygen) going back into bottom of the room..  The bottom pump(s) go to insulated pipes that  feed your base with oxygen.  That will prevent more hydrogen from escaping and prevent the electrolyzer (which produces a surprising amount of heat) from overheating your base.  Also the cold biome should make the oxygen cold enough to provide some cooling to your (hopefully well insulated) main base.

For loose hydrogen in a cavern or room, seal the room, put an algae deoxidizer at the bottom and let it run for a bit.  That will push all the hydrogen to the top.  Then build a gas pump at the top to capture/filter the hydrogen into a tank or down to your generator.  Disassemble everything when you're done.

Yes, electrolyzers. Due to me using recycled water for clean water for air. I also use algae oxyginators but electrolyzers seem way more effective. Algae farms don't seem to work enough. Though thankfully slime for the algae machine helps for the oxyginators.

I solved the problem with air tiles. Now the base is breathable again. Thanks guys. Finding out that hydrogen rises makes a lot of sense.

Pump all the excess hydrogen into a seperate room with wheezeworts. It will give you a head start later on when you want to make liquid oxygen. Since you'll already have hydrogen precooled to -60C. Takes a loooooong time to start up liquid oxygen machines.

Or you could send some pipes through that room when you want to cool down water for example.

[Derringer]

For what it's worth, I've had stupid quantities of hydrogen inadvertently produced by geyser shenanigans. My last base had a cooling water loop running behind a Cool Steam Vent, and the vacuum squares created by total condensation of steam somehow converted other gases in the area into hydrogen. This wasn't too bad in practice, since the resulting hydrogen tended to end up in tundra biomes where it greatly empowered the wheezeworts to help keep them cold, but it got annoying fast when the loose gas outside my living area envelope developed runaway high pressures.

Can you explain further on this? I've been trying that lately on my bases.

I normally use open systems at the start of the game (only top part / pump for you is interesting, to catch hydro).
