The fuel consumption of an Astrahus in the online spaceship game EVE Online depends on the modules used. Astrahus is a medium-sized citadel, a type of Upwell structure meant to be used as an operations base. Citadels do not consume fuel, but the service modules installed in them do. The fuel cost depends on the modules used, such as reprocessing, clone bay, and citadel modules. The lowest fuel consumption service for an Astrahus is the Standup Cloning Center I, which has a fuel reduction bonus.

Fuel usage depends on the modules used, e.g. reprocessing, clone bay
The fuel usage of an Astrahus depends on the modules used. For example, reprocessing, clone bay and citadel modules all impact fuel usage. Citadels, such as Astrahus, do not consume fuel, but the service modules installed in them do. The fuel cost is based on the modules used and the number of modules. Each module has a different fuel cost, so the total fuel cost for an Astrahus will depend on the specific combination of modules being used.
The Standup Cloning Center I is a low fuel consumption service for an Astrahus, with a 25% reduction in fuel consumption. However, there is no reduction for the cloning service on engineering complexes and refineries, as it is a citadel-class module. EC and refineries have different fuel reduction bonuses.
If you are using citadel modules with citadels, you will get a slight decrease in fuel cost. The same goes for engineering modules with engineering complexes. Engineering complexes are structures used for research and manufacturing, and they consume less fuel.
To calculate the exact fuel cost of an Astrahus, you can use the in-game fitting tool to simulate the Astrahus/EC fit and see the fuel usage. This will allow you to determine the fuel cost of each module and calculate the total fuel cost based on the modules you plan to use.

Fuel reduction bonuses are available for certain modules
The fuel consumption of an Astrahus depends on the modules used. While the Astrahus structure itself does not consume fuel, any installed service modules will. There is an initial onlining cost of three days' worth of fuel, which is taken from the fuel bay when a service is put online. Once online, the service module requires fuel to remain active, which is also drawn from the fuel bay hourly.
Different services use different amounts of fuel, and the fuel usage of a service module may be affected by structure bonuses. For example, the Citadel structures have a bonus that reduces fuel use for any Citadel-specific service modules fitted to that citadel. Similarly, when using citadel modules with citadels, there is a slight decrease in fuel cost, and the same goes for engineering modules with engineering complexes.
Other modules for Upwell structures do not consume fuel, and structure rigs can be used to improve certain aspects of structure usage. Larger structure rigs can improve a larger number of attributes at once, providing the same rig bonuses as multiple medium structures.
The lowest fuel consumption service for an Astrahus is one for which it also has a fuel reduction: the Standup Cloning Center I (10 bph base, 720 blocks to online = standard 3-day cost for all services). It is believed that the reduction makes it CCP_ROUND(10 bph * (1 - 25%)) = 8 bph.

Citadels don't consume fuel, but their service modules do
In the game EVE Online, Citadels are Upwell Structures meant to be used as operational bases. They come in three sizes: Astrahus (medium), Fortizar (large), and Keepstar (extra-large). While Citadels themselves do not consume fuel, their Service Modules do. These Service Modules, such as cloning, market, and reprocessing modules, require fuel to function and have associated fuel costs.
The fuel consumption of a Citadel depends on the modules installed and utilized. For example, the Standup Cloning Center I offers a low fuel consumption service with a base consumption of 10 bph and a standard 3-day cost for all services. Certain citadel modules, engineering modules, and citadel-class modules like cloning services on engineering complexes and refineries can provide a slight reduction in fuel cost.
The fuel usage of a Citadel can be simulated using the in-game fitting tool, which allows players to estimate fuel consumption based on the intended use of the structure. The "My Structures" tab in the game also provides valuable information, displaying the remaining fuel levels and the current state of vulnerability of the Citadels.
To manage the fueling process, a player must assume control of the Citadel by docking and clicking the "Take Control" button. They can then access the fuel bay by opening the cargo hold and navigating to the appropriate hangar in the dropdown menu. It is important to note that fueling a Citadel adds an additional timer, indicating the structure's vulnerability.
By understanding the fuel requirements of different modules and utilizing tools like the in-game fitting tool and the \"My Structures\" tab, players can effectively manage their Citadels' fuel consumption and maintain their operational status in EVE Online.

Quantum Cores are required to bring structures online
In the game EVE Online, Quantum Cores are an integral part of the structure deployment process. The first step in deploying a structure is the 24-hour anchoring phase, during which the structure is vulnerable to attack. Once this phase is complete, the structure becomes dockable, and a Quantum Core must be installed into the Core Room, which is the most central and heavily protected location within the structure.
The installation of the Quantum Core initiates a 15-minute repair timer, after which the structure transitions to the shield vulnerable state. If no Quantum Core is installed, the structure remains in the onlining vulnerable stage, where the hull HP layer is exposed, and it is susceptible to destruction. The Quantum Core is designed to survive the destruction of the structure and will drop 100% of the time upon the structure's explosion.
Each structure requires a specific variant of the Quantum Core, which can be purchased from NPC corporations on the market. These cores are only available through the PLEX store and cannot be manufactured. They serve as an additional fuel requirement, temporarily removing ISK from the game as structures are built and destroyed.
The fuel consumption of an Astrahus, a type of structure in EVE Online, depends on the modules used, such as reprocessing or clone bay. While it is possible to have an Astrahus without any service modules, it will remain in a low-power state, skipping the armour timer if reinforced. The Standup Cloning Center I service offers the lowest fuel consumption for an Astrahus, with a 25% fuel reduction bonus.

Citadels have the shortest vulnerability durations and strongest combat options
Citadels, such as Astrahus, Fortizar, and Keepstar, are Upwell structures in EVE Online meant to be used as operational bases. They come with several advantages, including bonuses to combat rig effectiveness, market service fuel usage, and cloning bay fuel usage.
Citadels have the shortest vulnerability durations and the strongest combat options, making them easier to defend. Their vulnerability is linked to their fuel consumption, which is determined by the modules used, such as reprocessing and clone bay. Citadels themselves do not consume fuel, but the service modules installed in them do. The fuel cost depends on the specific modules utilised, and using citadel modules within citadels offers a slight decrease in fuel cost, similar to using engineering modules with engineering complexes.
The Standup Cloning Center I is an example of a low-fuel consumption service for an Astrahus. It has a base consumption of 10 bph, and the standard three-day cost for all services. Additionally, citadels can be in different power states depending on their service modules. When at least one service module is online, a citadel is considered to be in "Full Power" mode, gaining an additional reinforcement cycle if attacked.
Citadels offer a range of services, including cloning, market, and reprocessing, which were introduced with the Citadel expansion in 2016. They are versatile structures that provide strong defensive capabilities and efficient fuel usage, making them valuable assets in the world of EVE Online.
