New Gases & Liquids


This update adds eight new gases and liquids to the game, each with unique properties, phase behaviour, and uses. Volatiles has also been renamed to Methane to better reflect what it actually is. Stationpedia has also received an update to help convey the new gasses, and all their properties as much as possible.



Fuels & Oxidisers


Hydrazine is a monopropellant fuel that requires no oxidiser to combust, only a heat source or a spark. It is a stable liquid at room temperature and human livable pressures, but leaving free standing pools of it laying around likely isnt safe. Due to it reacting with itself, you can always ensure complete combustion once initiated.

Hydrogen is the most efficient fuel by weight, and combustion temperature, for rocketry. When combusted with Oxygen it burns cleanly into Water(Steam), making it a natural fit for bases running hydroponics or electrolysers. Liquid Hydrogen is also available.

Liquid Alcohol is a versatile room-temperature liquid only fuel that can be produced using the new Fermenter. It will irreversibly evaporate into Methane, so be sure to maintain its temperature and pressure properly to keep its form.

Ozone is a highly energetic oxidiser. Like Nitrous Oxide it will create faster combustion, compared to oxygen, when burned with a fuel. It is liquefiable and has a broader liquid range and lower latent heat making it easier to work with compared to NoS.

Coolant & Heat Storage


Silanol is the premium refrigerant for phase-change heat pumping. It has an extremely high heat capacity and a wide liquid range, making it more capable than Pollutant as a working fluid. Liquid Silanol is also available.

Liquid Sodium Chloride remains in liquid form at extremely high temperatures, making it an excellent medium for storing heat energy. At room temperature it exists as a solid. Sodium has no gas form and will decompose into Pollutant if heated too high, or if exposed to too low of pressures. It is best processed in a hot furnace, and tapped off via the liquid connection, to prevent 'low' temperature salts from freezing in pipes.

Inert


Helium is a fully inert gas. It will neither freeze nor condense into liquid, making it a useful working gas in atmospherics systems where phase-change needs to be avoided.

Hazardous


Hydrochloric Acid is a highly toxic gas that is liquid at room temperature and pressure. It has been added to the global atmosphere of Venus.

Ice prefabs and gas filters have been added for all new substances. A small amount of Hydrogen has also been added to Vulcan's global atmosphere, and to volatile ice ore.



Combustion Overhaul


Combustion has been fully refactored to be data driven. This allows each fuel and oxidiser to have its own unique reactions, rather than all combustion following a single shared model. The H2 Combustor has been updated to use the standard combustion code, with output products depending on the input gas mix. This means producing your own water is now different, and you'll want to look at all the combustion methods to find the best source of water for your world and setup.



To help make sense of the new chemistry, the Stationpedia gas pages now include a Combustion Info Panel. This shows the input ratios, auto-ignition temperature, and output products for any gas that will combust with the one you are currently viewing.



Fermenter


The new Fermenter converts plants into Alcohol. Different plants give different yields, so it is worth considering what you grow if Alcohol production is a priority. Sugar Cane, Corn, and Switch Grass are among the higher-yielding options. Seeds can also be fermented directly, and even decayed food will produce a small amount rather than going to waste.

The fermentation process produces a small amount of Polluted Water as a byproduct, which feeds naturally back into a hydroponics loop.



Ore Detector


The Ore Detector is a new handheld tool that replaces the basic Cartridge Ore Scanner, which has been deprecated. It has been added directly to the Mining Supplies box.





Liquid Filtration


The Liquid Filtration Machine is now available. It works similarly to the standard filtration machine but can handle liquids as well as gases.





Getting the New Gases


All of the new gases and liquids are available through traders and space mining, so you have options for how you source them depending on where you are in a run. These new gasses will open lots of gameplay possibilities, and we're eager to get feedback on if your happy with how you can use them, if you can get them easily enough, and in high enough quantities.

Traders


The Gas Trader has been expanded significantly to accommodate the new gases. World-specific bulk gas purchases now accept gas at or near the temperature of the world atmosphere. On Vulcan, for example, the Gas Trader will now buy Methane and Hydrogen at up to 140 degrees C. Buy prices have been adjusted to reflect this.

Helium, Hydrogen, Silanol, and Ozone have been added to Medium and Large Gas Trader sells. Hydrochloric Acid has been added to the Bulk Dirty Volatiles sell. Liquid Hydrogen, Liquid Hydrazine, Liquid Ozone, and Liquid Hydrochloric Acid are now available from the Liquid Trader. Salt has been added to the Ore Trader's selling items, and a Bulk Carbon Dioxide buy has been added for Mars.

Large Traders now carry more bulk goods, with the bulk multiplier raised from 1.5x to 2x.

Space Mining


The new gases have also been added to the space map as mineable gas cloud nodes, giving you a way to source them directly once you have a rocket up and running. Some minor tweaks have happened across all the planets' maps, as we tried to integrate the gasses, while still maintaining the purpose and lore of existing sites. The space map widgets have been update slightly to allow for better readability of sites with multiple ices/gasses.
