Use the "Carbon separation" recipe in the Chemical Plant. That will separate "Carbon dioxide gas" into "Carbon gas" and "oxygen gas". That will craft you the "carbon gas" you need to progress. I see you're playing Bob's/Angel's, maybe that might be messing with some things? The planet hasn't been tuned around Bobs/Angels yet.

Got it, thanks for the answer, maybe Bob's has some effect. I tried to separate Carbon dioxide gas, but it didn't help.

From what I saw in the Factoropedia, "Technology" requires creating liquid carbon, but there is no way to make it, there is only gaseous carbon.

Also getting this issue, no Bobs/Angel's mods installed. 2.0 Recipes and Independent Gases are set.

Poked around in the code to see if I could find the issue myself and I suspect you have a duplicate "carbon" entity. You define your version of the gaseous carbon produced in the chemical plant as: 'vesta_carbon', however the technology is requesting 'carbon' directly. Perhaps you meant to wrap it in your get_gas_name(name, alternative) function?

It's called "Carbon gas" but it is still treated as a fluid as in Factorio you only have two major prototypes of ingredients in recipes: "items" which are fed by inserters/loaders, and "fluids" which are fed by pipes. There is no difference between "gases" and "fluids" except for the graphical representation in pipes/storage tanks.
There is no duplicated carbon either, the issue is with the independent gases: I didn't write in a detection for if it was on or not, it just wants "carbon" which the independent gases always puts out "vesta_carbon" fluid instead of the global "carbon" fluid. The issue is fixed now though.

Got it, thank you very much!
