Small Hydrogen Tank (Small grid)
The Hydrogen Tank was added into Space Engineers in Update 01.105 as part of their Hydrogen update.
- In Update 1.194, the Small Hydrogen Tank variant has been added. Both Small and Standard tanks are available for large grid and small grid ships.
- The Heavy Industry DLC adds a spherical large-grid tank as an aesthetic variant with the same functionality.
Usage[]
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.
Tanks are also helpful as a reservoir to recharge the engineer's jetpack from the Medical Room or Survival Kit, or to refill Hydrogen Bottles.
Damage Mechanics[]
Since update 1.200, when Hydrogen Tanks are grinded/damaged below the red line, they slowly leak fuel, and they explode when destroyed.
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[]

You control filling and emptying of tanks in the Control Panel Screen.
- 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.
Capacities[]
| Type | Capacity (litres) | Ice to fill (tons) | Cargo containers to fill |
|---|---|---|---|
| Small Grid small Hydrogen Tank | 15,000 | 0.75 | 2.22 small cargo containers |
| Small Grid Hydrogen Tank | 500,000 | 25 | 2.74 medium cargo containers |
| Large Grid small Hydrogen Tank | 1,000,000 | 50 | 1.18 small cargo containers |
| Large Grid Hydrogen Tank | 15,000,000 | 750 | 17.76 small cargo containers or 0.66 large cargo containers |
| Type of Thruster | Large H2 Tank | Small H2 Tank |
| Large Hydrogen Thruster (Large Grid) | ~52 Minutes | ~3.5 Minutes |
| Small Hydrogen Thruster (Large Grid) | ~311 Minutes | ~21 Minutes |
| Large Hydrogen Thruster (Small Grid) | ~22 Minutes | 38 Seconds |
| Small Hydrogen Thruster (Small Grid) | ~103 Minutes | ~3 Minutes |
Drain times are based on the large/small H2 tank of the same size grid as the thruster.
