I need an electric engine, so need LUBRICANT so need ... lithium.
Can't get it if i wasn't at Aquilo. Tech is locked. So i stuck here?
Maybe add "electric engine" recipe with "lithium brine" and "ammonium" ?
Also can't void ammonium. This is gas but can't void via "vent stack".

The cryogenic plant can make lithium, and there is lithium brine on the map.

i wasn't as at Aquilo so there is no such recipe. The tech is locked.

The recipe 'lithium' is unlocked in the technology Fulgoran Cryogenics.

The recipe 'lithium' is unlocked after:
1) Fulgoran Cryogenics
AND
2) Lithium processing (which unlocks AFTER "Mine [Entity: big lithium ice formation]")
So the tech is locked.

The technology Fulgoran Cryogenics has the recipe 'lithium' as an UnlockRecipeModifier. This means when you research this technology, the recipe becomes unlocked.

If this is not the case for you, can you please tell me what other mods you have installed?

thousands of them:

That screenshot looks as expected. Compare it to the Factoriopedia entry for Iron Stick.

The tech is gray - locked.

I don’t see what you’re referring to. Is the recipe unavailable when you look inside a chemical or cryogenic plant?

there is no such recipe. It will unlock after i pick up [Entity: big lithium ice formation]

until you thinking, my solution is:
cerys_tech({
science_count = 500,
name = "cerys-lubricant-synthesis",
effects = {
{
type = "unlock-recipe",
recipe = "lubricant-synthesis",
},
{
type = "unlock-recipe",
recipe = "lubricant-synthesis-hack",
},
},
prerequisites = { "cerys-advanced-structure-repair" },
icon = "Cerys-Moon-of-Fulgora/graphics/technology/lubricant-synthesis.png",
icon_size = 256,
}),

data.raw.recipe["lubricant-synthesis-hack"].category = "chemistry-or-cryogenics-or-fulgoran-cryogenics"

merge(data.raw.recipe["lubricant"], {
name = "lubricant-synthesis-hack",
always_show_made_in = true,
icon = "Cerys-Moon-of-Fulgora/graphics/icons/lubricant-synthesis.png",
icon_size = 64,
subgroup = "cerys-processes",
order = "e-a",
enabled = false,
energy_required = 3,
ingredients = {
{ type = "fluid", name = "light-oil", amount = 50 },
{ type = "fluid", name = "lithium-brine", amount = 50 },
{ type = "fluid", name = "ammonia", amount = 50 },
{ type = "item", name = "carbon", amount = 10 },
{ type = "item", name = "holmium-plate", amount = 1 },
},
results = {
{ type = "fluid", name = "lubricant", amount = 50 },
},
auto_recycle = false,
}),

To clarify what is going on here:
a) There is an incompatibility between Cerys and another mod which causes the recipe to be disabled even though the Cerys tech for it is unlocked. If you would like to identify the minimum set of mods that causes the effect, that would help the investigation.
b) Separately, you are misreading the Factoriopedia UI as meaning ‘AND’ rather than ‘OR’. I mentioned the iron stick UI since in the base game iron sticks can be unlocked by any single one of those technologies.
