How to deal with Hydrogen Vents?

[Russell]

So I'm on my the Oceania Asteroid (which is mostly salt water biome) and the only two vents/geysers I've found are both Hydrogen vents.

At first I though "Jackpot, free power!" but the Hydrogen comes out at a Dupe scalding 500c.

How to I deal with 500c Hydrogen?
The air pump with overheat and take damage unless I cool the gas first, but I haven't found an ice biome so how do I cool anything without Wheezeworts?

[Cotaks]

hydrogen can be harvested without cooling it. the amount it puts out is to small to get to 500c if you pump it out directly

[Zefnoly]

500c is a whole lot of heat energy. Pipe it through steam to cool it with steamturbines. That will give additional free power before you put it into hydrogen gens... Also if you cool it enough its free hydrogen for the thermonullifiers as well.

You go and try that and tell how it went XD

To handle that 500C hydrogen you need to lower its temperature, unless you have niobium. Hydrogen vents were buffed in launch update and now it generate lots of heat due to high SHC of hydrogen and increased average outputs. If you use steel pump then you need to drop temperature by at least 225C. I don't know stats of your vent but if by average it outputs e.g. 300g/s than it is 162kDTU/s of heat. You wouldn't want to use wheezeworts for that, especially if you will have to deal with temperatures above wheezeworts max level.

Your best option is aquatuner looping polluted water.

May be Petroleum as coolant? (538C vaporisation)

There are stupid amounts of relatively cool salt water on oceania. Just pump it through the room with vent, it will raise water temp by few C, then use those water, it shoud still be <40C...

If you want to be power efficient using aquatuner then you should use liquids with the highest SHC available to you.
10kg packets of pwater should not exceed 120C, but some failsafe is always a good idea.

Even if it is close to 120C than after reducing to 106C, by aquatuner, it should exit at 109C from vent chamber, if temperature inside is close to 275C. So you can loop it there untill it reaches temperature close to 120C and then send to aquatuner again.

Maybe use closed petroleum loop just to bring heat from geyser into other Petroleum pool (and even add Diamonds conveyour to make it faster). And using this pool as heater for steam turbine? Will it work or its stupid idea?

[Angpaur]

Yes, this would be great idea to utilize steam turbine. This is an ultimate solution.

Yes, sounds doable. Unfotrunately dont have Hydrogen Vent to test it in current world.

[TadaceAce]

Pump it through a large water reservoir. Put steam generators on top of reservoir. Cools hydrogen, generates power.

This is correct. There is very little heat energy behind the hydrogen that comes out and it almost instantly cools to much lower temps even in a near vacuum. Just stick a gold (probably not required) pump in there and feed it directly into hydrogen generators.

When area surrounding the vent is still cold it will work temporarly. But you are heating up that area, so it won't last forever. Observe the pump's temperature and check how it is rising each cycle, after vent eruptions and you will be able to estimate how much time you have before everything overheats.

[Astasia]

Eventually ya, it's creating some heat and if you do nothing about it at some point it will become an issue. That setup has been running for over 50 cycles in that game though.

[Jarcionek]

No need for steel, niobium or petroleum.

Place radiant pipes and temshift plates behind the geyser and loop polluted water through it. Change the water either when it has 0 germs or if temperature exceeds 90C or 110C (whatever you can handle).

If you don't have aquatuner water cooling system yet, dump that hot water into space.

Alternatives would be to cool it with anti entropy thermo nullifier, if there is one nearby, or with wheezeworts, but I don't know how many you would need.

For example the vent from Astasia's screenshot has 116g/s average output so it could seem that 10 wheezworts are enough. But problem is that during eruptions much more heat is released in short time and 10 wheezeworts will not keep up and will overheat when reaching 95C. And then no more cooling.

You can prevent this with making a heat buffer big enough to give wheezeworts time to stabilize temperature again. However in practice the buffer can be just too big to build, if it has to consist of more than 100 tiles filled with high heat capacity stuff like water, thempshift plates or gravestones.

I would not suggest using wheezeworts to cool down vents.
