Oxygen
Concentrated Liquid Fuel 34 
Oxygen is a raw material in No Man's Sky. Integral to the atmospheric filtering technology at the heart of the exosuit life support system. Exosuit material processing allows oxygen to be harvested directly from appropriate planetary flora. Other plantlife may be scanned with the Analysis Visor to reveal alternative oxygen supplies. To craft it, combine Kelp Sac x1 in a Refiner.
