Storage tanks will only be filled to the same percentage of capacity as pipes that lead to it. Pipe that always carries about 50 water will fill the tank to about 50% of its capacity. [[Pump]]s can be used to fill the entire tank from a low pressure source (such as distant [[pumpjack]]s).

There are several advantages to storing energy in storage tanks compared with storing it in an accumulator:
=== Calculations ===
* The energy density of a storage tank tile is much higher than it is with accumulators.
** For 165°C steam (produced with [[boiler|boilers]]), a single storage tank stores as much as 15 accumulators: <code>750MJ / 5MJ = 150</code>
** For 500°C steam (produced using [[Heat exchanger|heat exchangers]]), a single storage tank stores as much as 48 accumulators: <code>2400MJ / 5MJ = 480</code>
* A  [[nuclear reactor]] always fully burns a fuel cell, releasing 8GJ (or more with the multiple reactor bonus) even if power demand is lower. The excess energy can be stored as steam.
* A single [[accumulator]]'s maximum discharge rate is 300kW. On a very heavy load (e.g. laser turret firing), a small accumulator array may not discharge fast enough, causing power disruptions. A steam engine can produce 900kW of energy from the stored steam (3 times faster discharge rate), and a turbine can produce 5800kW (6.4 times faster discharge rate). In other words, a number of turbines or steam engines with steam storage can cope with much higher bursts than the same number of accumulators.
* Steam can be transferred via trains and then consumed remotely via turbines or steam engines. This essentially "transports electricity" using trains.
 


* 1 '''Storage tank''' can store 25,000 units of 500ºC steam.
* 1 '''Storage tank''' can store 25,000 units of 500ºC steam.

The storage tank is a building that can store up to 25,000 units of a fluid. It is a passive storage — it has no input and no output, depending on pressure to fill it, essentially acting as a large pipe.

Usage

Storage tanks will only be filled to the same percentage of capacity as pipes that lead to it. A pipe that carries about 50 water will fill the tank to about 50% of its capacity. Pumps can be used to fill the entire tank from a low pressure source (such as distant pumpjacks).

The storage tank is often used to store raw materials and excess products from oil processing, allowing a refinery to run without interruptions. It can also be connected to the circuit network, sending the fluid contents as a signal to the network.

The fluid inside the storage tank can be destroyed by flushing the storage tank or the whole fluid system in the GUI, or by mining and rebuilding the storage tank. The storage tank can be emptied without destroying the contained fluid by draining it with a pump. Mining a storage tank will send its contents to the next nearest storage tanks, if the fluids match.

Storage tanks can also be used as a replacement for accumulators. If steam consumption by steam engines or turbines changes a lot over a daily cycle (for example due to solar panels or laser turrets), storage tanks can be filled with steam during low power usage and then emptied during heavy load.

A storage tank filled with heat exchanger 500°C steam stores around 2.4GJ; a storage tank filled with boiler 165°C steam stores 750MJ.

Calculations

  • 1 Storage tank can store 25,000 units of 500ºC steam.
  • 1 Steam turbine can output 5,820kW = 5,820kJ/s using 60 units of 500ºC steam/s.
  • 1 Storage tank can keep 1 steam turbine working at full capacity for 25,000 ∕ 60 ≈ 416.6667s
  • A Storage tank can store up to 25,000 ∕ 60 × 5,820 = 2,425,000kJ using 500ºC steam.


  • 1 Storage tank can store 25,000 units of 165ºC steam.
  • 1 Steam engine can output 900kW = 900kJ/s using 30 units of 165ºC steam/s.
