How to fill hydrogen engine?

[Bergerson]

Hi.
I have hydrogen engine hooked through conveyor system to hydrogen generator and hydrogen tank. Tank is filling with hydrogen engine not.
How do You fill it??

[SpaceMan62]

Make sure only the engine is filling. It won't fill up if something else (either another engine or a tank) is also filling.

What SpaceMan said. Also, some mods have been breaking things. I had this issue myself in my Lunar game currently.

If you have a hydrogen tank connected to a h2/O2 generators full of ice and its not filling make sure the h2/O2 gen is set to fill tanks and if it still isnt fill set the tank to stockpile. If the tank is on stock pile tho it will not fuel thrusters

I had this same bug, use control panel and turn engine off and then on again. Seems to work after that.

[CowCompressor]

Same here. Rebuilding the stuff and have a battery to start it did not help.
Only a Save/Load action helped.

Thank You all

I can't fill the internal tank on my hydrogen engine either.

If I turn it off, the 02Gen stops cracking ice. If I turn it on, the 02Gen starts up again and the hydrogen engine burns all of it's hydrogen (and producing 50% power) rather than filling up the internal tank.

Switching on and off again or grinding and rebuilding has no effect.

you have to shut down the whole grid with "Y" and you need some energy to start the engine.

At the end, this engine is useless. wind and/or solar is way better and not so stupid designed like this engine.

Cupit, to fill the engine, you need to produce more H2 than you're burning. Adding another O2/H2 gen may just be the thing you need. Large grid engines consume more than a single gen will produce. A small grid engine will run on a single gen, but not really fill the tank if burning at full power.
Edit: And yes, the blasted engines will ONLY fill while running.

The engine won't fill in an off mode, turn it on then off if it's connected to the conveyor system.

It might be your batteries that are recharging. Hydrogen engines also act as alternators to recharge your ship batteries.

I've figured out the bug there.
Frist you need to make sure that you don't use one conv. for ice and hydro.
Second, if you have few tanks in line and than engines, drain all hydro into the closest tank and disassemble empty tank.
Then disable drain mode. Your engines will start!
After that you can restore your hydro line.

had placed several hydrogen tanks - filled em up - startet engine - engine starts to suck hydrogen - engine works
the engines seem to burn hydro faster than a O²-Generator can produce. make sure you have some hydrogen in store

[rednuke008]

if you have a hydrogen tank and you turn the engine on for a second it will pull hydrogen from the tank into the engines own tank

If I remember right the current ration to O2/H Generators to HydroEngines is 3-1. So you need three generators to outpace the engine for hydrogen production to consumption.
