How do I craft Deuterium in No Man's Sky?

To craft Deuterium, you need Di-hydrogen x1, Tritium x1. Use the Refiner to combine them.

What ingredients do I need for Deuterium?

You need: Di-hydrogen x1, Tritium x1.

Deuterium is a high energy substance in No Man's Sky. The best yield: refine Di-hydrogen x1, Tritium x1 in a Medium Refiner.

1 batch: 1 Di-hydrogen + 1 Tritium in a Medium Refiner makes 1, about 0.24s in one refiner.

Best yield per input first

Times are approximate, per batch (one run of the recipe). In-game refiner timers are often off.

A stable hydrogen isotope used heavily in both small-scale fusion reactors and neutron-scattering shield technology.

Deuterium very rarely occurs naturally. Most of the galaxy's supply comes from the processing of Di-hydrogen and Tritium in Refiners.
