Summary
Hydrogen, the most abundant element in the universe. At first, when a player starts to get Hydrogen, they have very little use for it, and may consider it a nuisance. By late game, however, Hydrogen may very well become your bottleneck. There are many ways to get Hydrogen, including several different recipes, as well as gathering it directly from Gas Giants using Orbital Collectors.

Player Tips & Tricks
Hydrogen can also be stored in storage tanks, since it's a fluid.
In late game, hydrogen can often build up and clog the production process. You can prevent this by either burning it in a thermal power station, and/or craft it into the more energy effective hydrogen fuel rods and then burning it.
You can also use leftover hydrogen to craft it into deuterium, which can either be used as a material in multiple crafting recipies, or burned in a mini fusion power station after crafting it into deuterium fuel rods.
