Correct, hydrolox engines + water electrolysis (+ liquefaction & storage) might be the solution. However I don't use RealFuels / CryoEngines in my actual JNSQ game. But - do you (does anybody?) know how gaseous H2 and gaseous O2 are turned into LOX and LH2 in these mods? Do I need another converter (liquifier, in fact)? Is it included in CryoEngines/RealFuels/somewhere else? What about boil-off? I don't like to discover that my freshly liquified H2 turns into vapour and happily escapes to space... Appreciate your advice.

Check FAQ Q: My probes use 12 EC/s for comms and die within seconds!

Thanks, but it wouldn't work. Electrolysing water gives you H2 and O2. However for Sabatier process (making LF) we need CO2, and the only CO2 source is regolith (Molten Regolith Electrolysis). I found another solution: modifying default profile (default.cfg is located in /KerbalismConfig/Profiles). I looked into it, and I found this: Process { name = molten regolith electrolysis title = #KERBALISM_Process_MoltenRegolithElectrolysis modifier = _MRE input = [email protected] // 2 kW MRE reactor at 2300 K with heat corrosion resistant crucible input = [email protected] output = [email protected] // 42% of regolith is O2 output = [email protected] // approx 2% of regolith is CO2, released in the pre-heating stage @950K Here you see there is assumption that 2% of regolith is CO2. To justify the modification, I assumed, that in Kerbol system the regolith contains 42% of CO2 I noticed: both ModuleManager.ConfigCache as well as default.cfg should be edited, else the game breaks.

Hi all, Kerbalism is wonderful mod. I have however a question regarding ISRU on no-atmosphere bodies. The problem is in CO2 production rate from molten regolith. To satisfy the CO2 demand of a tiny Sabatier (tiny = Chemical Plant) which is 6,981/s I would need 43 pcs (!!!) of small MRE (small = Covert-O-tron 125), or 9 pcs of big MRE (big = Convert-O-tron 250), with double MRE. And probably a nuclear plant to satisfy power demand for such a monster, because requirement is 3240 EC/s for 9 big MRE, which is something like 135 pcs of Gigantor XL solar arrays at Kerbin Still, this monster would make only 3,6 LF per hour! Jumbo 64 fuel tank (the good old "orange" one) has 2880 LF. To fill it I would have to wait 800 hours. Realistically speaking, I can make a plant with 2 x Covert-O-tron 125 MRE, 1 tiny Sabatier + the other stuff (H2O electrolysis), and such plant could make 99 (!!!) units of Liquid Fuel in about ... 600 hours is there any other trick? Waste incineration looks promising, but where to get waste from? I know, plenty on Earth, but not on Mun or Minimus... Can I do something? Or forget it and create big tankers and ship the fuel everywhere from Kerbin? Because ISRU makes no sense with such production rates. I'm playing JNSQ, this is not so cheap... Thanks for your advice!
