Hydrogen storage is essential for ships using Hydrogen thrusters. An O2/H2 Generator needs to constantly melt ice to create hydrogen, and cannot keep up with hydrogen thrusters, that's why you rely on tanks for stockpiling enough gas before a longer flight.
Since update 1.200, when Hydrogen Tanks are grinded/damaged below the red line, they slowly leak fuel, and they explode when destroyed.
(big brain tip: smart people use hydrogen as starter warheads for bombing)
Construction[]
Standard cylindrical Hydrogen Tank (small grid next to large grid variant)
All hydrogen tank variants can be built on large grids and small grids.
The standard Hydrogen Tank is boxy in shape and 3x3x3 Length x Width x Height. Built on large grid, it has six large conveyor ports, one in each of the six directions, in the middle of each side. Built on small grid, it also has six ports, but it's four small ports all around the cylinder, and two large ports on the head and top of the cyclinder.
The canister shaped Small Hydrogen Tank built on a small grid is 1x2x2 Length x Width x Height, and it has two small ports, one on each narrow side. The cylindrical Small Hydrogen Tank built on a large grid is 1x1x2 Length x Width x Height, and it has two large ports, one on top and one on the bottom.
The tank must be powered and connected through a conveyor circuit to be of use.
Emptying and Filling Tanks[]
Small Hydrogen Tank (large grid with small grid variant on top)
Enable Stockpile to have the tank pull available hydrogen from the O2/H2 Generator or from other tanks. Hydrogen thruster and medical rooms' hydrogen recharging will not work while all tanks are on Stockpile.
Disable Stockpile to allow Hydrogen thrusters and the Medical Room to use up hydrogen from this tank, or to transfer hydrogen out of this tank into a stockpiling tank.
A cracked or grinded tank slowly loses all its Hydrogen gas.
Status lights[]
black - empty or below 25%
all red - no power or switched off
Yellow - not connected to complete conveyor line/broken conveyor line
all blue - accepting hydrogen, not providing (Stockpile On)
green - providing hydrogen to e.g. thrusters (Stockpile Off)
The four indicator lights light up one after the other for each 25% filled.
