Too Much Hydrogen

[ArtistRei]

So for the past 400 cycles or so, I've been using this SPOM setup for my oxygen needs, only problem is that it produces a lot of Hydrogen. Most of it is stored in tanks as you can see, but it'll eventually all fill up and I don't wanna expand that system. Do you guys have any ideas on what to do with the excess?

compress?

you could store it infinitely if you condense it to liquid then send to reheat using a valve set to 1000g/s then to storage room.

or you could using an exploit liquid (<2kg) over vent.

Hydrogen generators turn hydrogen into power for your base.

Alternatively, you could build a hydrogen liquifier and store it for a liquid hydrogen rocket when you head to space.

Or you could build a room using a flooded vent and just store it until you decide what you want to do with it.

Is there an easy way of making Liquid Hydrogen without using super coolant?
If that doesn't work well with me, I'd probably just vent it somewhere.

BURN IT!!  BURN IT ALL!!!  No, seriously.  Just because the SPOM is "self-powered" doesn't mean you aren't allowed to use the excess power or hydrogen.  Also, save some for your AETNs, which are OP, and for any serious wheezewort action, since that maximizes their cooling power.

Nope, the only way to make liquid hydrogen is with super coolant.  Nothing else gets cold enough without freezing solid.  Once you HAVE liquid hydrogen, you can use it to make more..

I see, thanks for the insight.

I am considering just using it for power, just trying to find something in my base that doesn't need constant power so it can last 100+ cycles

and I actually have 3 of them, one I'm currently using to cool down my "factory" (Polymer presses and Metal refineries)
They're all very far apart from each other.

Generally I have my generators on one main power grid and then my various consumers are all powered by transformers that are connected to the main grid.  In this way I can use smart batteries to control my generators with various priorities.  For example:

If I set the smart battery of one generator to kick on at 50% and run to 95%, then I set another smart battery to kick on at 35% and run to 70%, the first generator will run most of the time.  The second will only kick on when power demand gets high enough to drop the batteries down to 35%, but it will turn off once levels are nominal (70%).  

With that in mind...

If you have 10 (or more!) dupes and you produce their oxygen exclusively by electrolysis, then you can run one hydrogen generator continually and still have a small amount of hydrogen to spare.  Assuming you have 10 dupes that are normal breathers, they'll be using 1kg O2/s.  An electrolyzer turns 1000g H20 into 888g O2 and 112g Hydrogen.  So, if we scale it up to 1000g O2, then you'll be producing 126g/s of hydrogen.  One generator burns 100g/s hydrogen, leaving 26g to save up or spend in AETNs.

It's a good idea to build a reservoir or 5 near your AETNs so they can stay online for many cycles unattended, since it can take a long time to cool down to the desired operating temp.

This isn't quite true, as there are some tricks to make LH2 without super coolant.  That said, the only practical way to make a lot quickly is with SC.

....I thought that it had been proven that it is quite possible to create L-H2 without Super Coolant.  Isn't it a build that uses L-O2 or something?  It's just that it produces at such a small rate and you have to deal with the headache of keeping it a liquid...

I actually have 4 tanks right next to it. It should last for about 100 cycles when all 4 are filled

 

I decided to connect my other SPOM (I use this one to fill my Atmo Suits) to my power grid. Works well enough.

I've seen one person do it.  Its very finicky.    You also have to deal with rates that are under 1000g/s to avoid O2 solidifying in the pipes and the temperature is so close to hydrogen's evaporation point that trying to pump it into pipes vaporizes much of it.  Certainly it IS possible, but...
