Hydrogen-SPOM

[Ksajural]

i've 2 spom and they are working well, lateley i found an Hydrogen vent and i'm setting up an AETN, i built many gas reservoirs but i'm scared about the vent dormancy, here the question:

i want to connect my spom to the powergrid in order to use the hydrogen to fill the tanks during the vent dormancy but i don't want the pipes blocks when the tanks are full (creating problem on oxygen generation inside the SPOM) and use the excees to fill the hydrogen generators (connected to the main power grid i guess).

how can i do that?

If you put a gas valve on the SPOM's hydrogen pipe and have the output go to spom generator and/or spom storage tanks the excess hydrogen only will bypass the valve and go to your main tanks/generators. Like so: 
(Note: Spom here is just a placeholder and does not work)

What you're asking for here is a bypass for excess, and the simple way to do that is to run the pipe over and past the input; only when the tanks block flow into them will the gas in the pipes go past the input and to your generators for deletion.

This is a very useful thing to know in general for piping because it establishes priority, and can be easily manipulated with bridges (because they provide an input to pipe over), like with letting off excess from a bathroom loop, or venting excess flow to space, or even backup detection by putting two bridges in a row and a sensor on the second (liquid trying to use the second bridge means backup).

It's not exactly what was asked, but in the end it gives unlimited storage

i never used valves before..

i've to set an amount of g/s right?

do you mean to set just the maximun amount and the excees will go on the upway?

is this similar to the bridges priority for liquid pipes (i use this of the excees of the bathroom infinite loop)

The valve is unnecessary, unless you are trying to create a super duper specific system.  In the general case, you just need to run your main Hydrogen line beyond the input of the local Hydrogen Generator (or it's Reservoir).  The simple fact is that the SPOM should generate more Hydrogen then the Generator will consume in equal time frames.

So, going back to the picture, run the Gas Pipe from the Pump, straight to the local Reservoir.  But don't stop the Pipe there, continue it on past it, to the second Reservoir for the main power grid.  Skip the Valve entirely.

but i want that the tanks of the AETN to have priority 1, if the hydrogen vent is off i want to use every single g of Hydrogen for the AETN tanks

fire up debug/sandbox mode and try out all the options that come to mind

So, to clarify.....

• You want to keep your SPOMs self-powering.
• You want to keep the AETN running continuously.
• You want any excess gas from either source to go into storage.

So, in that case, you'll probably have some piping spaghetti to deal with, but it's very possible to do what you want.

Somewhat simplistic drawing, but should communicate the idea.  The SPOM is symbolized in the top left, the Geyser source is the bottom left, and the pair of Reservoirs in the middle are the storage zone.

The SPOMs will prioritize themselves, feeding the Generator, then filling the local Reservoir, and after the Reservoir is fill the excess will "overflow" to the storage Reservoirs.  Independent from this, the Geyser will pump straight to the storage Reservoirs.  The AETN will always draw as much as it needs (it's still 10 g/s, right?  Not very much at all.) for as long as it is still supplied from the storage Reservoirs.

Notice the Gas Bridge where the lines meet, right before the storage Reservoirs.  You will definitely want to use a Bridge here to give one line or the other priority, but you have to decide which you want to do.  I defaulted to giving the SPOM source priority, with the SPOM flowing straight through and the Vent entering from the Bridge, since a SPOM that has backed up will get gases going the wrong directions.  But if you're concerned about gathering every last gram of Hydrogen from your Vent, you may want to give priority to the Vent source instead, by having the Vent flow straight through in Pipes, and the SPOM line entering from the Bridge.

If you were to then add more Hydrogen Generators to directly supply your power grid, you can again use a Bridge to give priority.  In that case, you'd create a line from the storage Reservoirs directly to the main grid Hydrogen Generator(s), and use a Bridge to direct the line to the AETN.  Gas will enter the Bridge before continuing along the pipes, ensuring the AETN will be the thing that runs first.  Any excess will continue flowing along to the main grid Hydrogen Generators.

no..

- I want to keep the AETN running continuously.

- i want that the hydrogen pump never stops

so i connect the electrolyzer setup to the main powergrid and don't care if it is not a "SPOM" anymore

my problem is use the excees of the hydrogen is some generators ONLY if all the tanks of the AETN are full.

but you gave me the answer with the gas bridge, i didn't now it works like the liquid bridge, in this case i can do this:

will this work?

if i don't put any automation wire to the hydrogen generators they will just run forever and the hydrogen pump of the electrolyzers will never stop right?

to don't waste energy i can set the natural gas generators (my main power supply) that activates below 70% of smart batteries and stops above 90% so the hydrogen generators will always run for the last 10% 

probably this is better:

so the Vent will never overpressurize and i will make the most of the Vent active time.

On the first one, no, because when the vent's active, it can end up backed up with nowhere to go. Your second diagram is however overcomplicated (you don't need a bridge, the tank's input works the same). This is all you need as far as gas pipes, with the AETN downward:

And for more tanks, it can be extended like so:

Now, where you would need a bridge for this is if it starts to get crazy with hydrogen throughput, because each pipe can only handle so much, so you would want a whole bunch of parallel paths with some crossover in case one's low (the bridges would simply be to prevent excess from one tank's input from trying to go into the other's input), like so:
