@Xeph you can make jelly in refiner, which costs 30, but takes a really long time

Just now tried this, it costs 40 DiHy to make a jelly, and you get 50 back in the refiner (I used the freighter refiner), so it's half as efficient as this guide is currently. You may want to update.

buy the jellys from space station they cost like 5 units and fill you hauler you can refine a whole hauler in minutes

Just mining it is way easier now since the updates from three years ago. You can have several multitools, so you can fix one up with a beefier mining rig and then everything you shoot disappears in ususally a half second. You can gather a great amount of critical resources by just shooting a lot while exploring, with no boring special tasks. Take advantage of those cable and metal planets in your discovered systems. It is also beneficial to have a base where what you seek is plentiful.

You don't need a big base, just a small building with a teleporter, a save unit, and one or two storage units from your freighter and your favorite exocraft. I sometimes pass by the little ones and just mine the big crystals. I never let those go. When I come to a field I line them up in a row and go straight up the line. It goes faster that way. Before the later updates you could aim for the last one in a line and all of them would pop like ballons. Now you must go uo or down the line.

Don't forget that you need tritium for the frigate fuel as well which i just fly around space every once and awhile and chew up some astroids for. alot of the smaller rocks seem to be tritium

Just buy Dihydrogen jelly, it's pretty cheap and you can easily buy around 60 of them for ~12k. Refining a stack of 20 gives you 1000. No time needed.

I used to craft frigate fuel, I got pretty efficient at di-hidrogen cycling.

Now i just steal it from frigates in space, way more efficient

I just use Minotaur/Car to mine a heck ton of di-hidrogen on a planet. It's generating everywhere. 10-20 minutes on a planet and you're good to go

Not many people use mining grenades (I forgot the actual name, just getting back into the game for 4.0) but let me tell you something: You can blast the hecc out of a dihi patch in mere seconds. So just going for a walk on a planet where it's in abundance will net you many stacks in a short time, especially /w a good tool.

frigate fuel needs are why the Di hydrogen is needed most. You can use other resources to power your other devices. Not frigate fuel. Must have the Di-Hydrogen to make the fuel. You can also buy Di-Hydrogen jelly and refine it into Di Hydrogen. That's how I eventually get my resource to make the fuel.
