Produces massive amounts of proliferated graphene and hydrogen even for post first dyson stage. Has proliferated hydrogen L1 cache for slightly faster supply injection during demand peaks or short term graphene oversupply. If placed on planet with huge hydrogen demand you could use it as an imported hydrogen proliferator through the caching system, just be mindful not to let it fill entirely, otherwise graphene production will stall and can be a headache until you track the issue down later.

This is very resource hungry. I don't recommend using this if resource scarcity is a concern. Also recommend putting this only on systems with fire ice for stable supply, otherwise it will oscillate production.

You could trim the outer edges to scale this down, and/or use normal chemical plants to halve the throughput. Should still work fine. If you're especially broke you could probably figure out a way to use only one ILS for whatever reason, but it also helps importing more fire ice quickly. You can play around with it, I'm not smart enough to make some ultra fancy system. This isn't the most space efficient build you'll find, but it's not needlessly big and it will shred as much fire ice you can throw at it.

Takes around a quarter of a planet's equatorial circumference, for scale. Around 37 squares wide.

Inputs:
Fire ice - 21.600/min
Mk.III Proliferators - more than 1/min

Outputs (Tested with ideal supply):

Hydrogen - 13.500/min

L1 Cache:
Hydrogen - 38.000

Total hydrogen storage: 48.000
