Storage

Storage exists as a reserve of fossil fuels in case of a deficit. However, they are different depending on fuel...

Oil

Oil Storage Tanks are connected to pipelines, and either sit en-route between the Refineries and the Oil Power Plant, or are adjacent to the Refinery.

Coal

Actual lumps of Coal are stored at the power plant in Coal Storage Facilities, a module for the plant in the form of a lot outside the buildings.

Coal Gas is stored in Coal Gas Tanks placed adjacent to a Gasworks.

Natural Gas

Natural Gas must be stored at the Refinery in Natural Gas tanks.

Uranium

Nuclear material must be stored in a Nuclear Storage Building. These buildings must be placed at the mines, the processing plants and the power plants.

In addition, you must ship spent fuel to Nuclear Disposal Sites every 1 year of in-game time (1 hour of play time).
