Can you store energy in Minecraft?

Quick Summary

Yes, there are a few different ways to store energy in Minecraft. The main methods are:

  • Using Redstone Flux (RF) in machines like capacitors and batteries from mods like Thermal Expansion.
  • Storing fuels like coal, charcoal, lava buckets, etc in containers.
  • Using compressed blocks from mods like Mekanism that store energy.

What is Energy Storage in Minecraft?

Energy storage in Minecraft refers to methods of holding and containing energy in various forms for later use. This allows you to stockpile energy or fuels now to power machines and devices later.

Some key examples include:

  • Storing electricity in batteries and capacitors using Redstone Flux.
  • Stockpiling fuel sources like coal, charcoal, lava buckets, uranium, etc in chests.
  • Compressing blocks of fuels into high-density cubes using mods.
  • Charging tools and items so they have internal energy to use later.

Having robust energy storage is crucial for building complex machinery, automation, and technology in Minecraft. The ability to store energy allows you to transport it from place to place and have reserves on hand when needed.

Storing Electricity with Redstone Flux

One of the main methods for storing electricity in Minecraft is using Redstone Flux (RF). RF is used by many tech mods and can charge items, power machines, and provide energy for various electrical devices.

Here are some key ways to store RF energy:

  • Energy Capacitors: These function like batteries and can be charged up with RF. Capacitors can then discharge electricity when needed to power machines and items. Popular capacitors come from mods like Thermal Expansion, EnderIO, and Mekanism.
  • Energy Cells: Very similar to capacitors, these cells are essentially rechargeable RF batteries. They provide portable power storage for tech mods and can be charged at power sources.
  • Lightning Rods: When struck by lightning during thunderstorms, lightning rods capture and store the electricity in RF. This energy can then be extracted as needed.

Key advantages of using Redstone Flux energy storage:

  • Transportable and rechargable power on demand.
  • Allows you to build up reserves of RF for future projects.
  • Powers a wide range of tech mods and machinery.
  • Items like capacitors can be charged from generators, dynamos, or other power sources.

With the right mods installed, RF energy storage is essential for mid-to-late game play in modded Minecraft.

Charging and Discharging RF Items

Charging up RF storage items is straightforward:

  • Place capacitor or energy cell in generator, dynamo, or other RF power source.
  • Provide input fuel for the power source like coal, lava, fuel oil, etc.
  • RF will automatically transfer from the powered generator into the storage item.
  • Check tooltip on storage item to see RF charge levels.

To discharge RF and use the stored energy:

  • Place charged capacitor or energy cell next to a powered machine.
  • Configure machine input to pull RF from the storage item.
  • As machine runs, it will drain stored RF from the item.
  • Monitor storage item tooltip to see RF levels decreasing.

With some Electricraft wiring and conduits, you can also transport RF power around your base or workshop.

Storing Fuels and Items

In addition to electricity, stockpiling fuels and burnable items is a good way to store energy in Minecraft.

Here are some standard fuels and energy sources that can be stored:

  • Coal/Charcoal: Obtained by mining coal ore or smelting wood. Burns to produce heat and RF energy.
  • Lava Buckets: Can fuel furnaces and other machines. 1 bucket = 1000 fuel units.
  • Blaze Rods: Can be compressed into blaze cake for high energy density.
  • Gunpowder: Can be used to make solid fuel blocks.
  • Wood/Planks: Can be used directly as fuel or charred into charcoal.

Key ways to stockpile fuel sources:

  • Mass produce charcoal by smelting huge amounts of wood.
  • Build tanks and reservoirs to store large quantities of lava.
  • Set up specialized farms, mob grinders, etc to farm fuels.
  • Create a centralized fuel storage room with chests, barrels, crates.

Benefits of amassing fuel reserves:

  • Prepared for future projects that require lots of power.
  • Seldom have to collect and produce fuels on demand.
  • Fuels like lava and charcoal are renewable and sustainable.
  • Stored fuels work for a variety of applications like furnaces, generators, etc.

In general, the more stored fuels and energy sources you have on hand, the more capabilities you will have in Minecraft.

Automated Fuel Production

To take your fuel production and storage to the next level, consider automating some renewable energy sources:

  • Wood Farm -> Charcoal: Use an automated tree farm to constantly produce wood, then auto-craft into charcoal.
  • Mob Farm -> Gunpowder/Blaze Rods: Grind mobs to collect massive amounts of gunpowder and blaze rods for future energy needs.
  • Lava Fabricator: Use buildcraft or other mods to generate infinite lava for storage and use.

Automated renewable energy production lets you stockpile huge reserves with little effort. You can build up to tens of thousands of units of charcoal, gunpowder, lava buckets and other energy resources.

Energy Compression in Modded Minecraft

Many mods add ways to take base fuels and compress them into ultra high-density energy blocks and items. This allows for extremely compact storage.

Some key examples include:

  • EnderIO Capacitor Banks: Can store millions of RF and provide massive energy reserves.
  • Mekanism Fuel Blocks: Compress charcoal, coal, etc into cubes worth 10x their normal value.
  • Draconic Evolution Energy Storage: Multiblock spheres can store trillions of RF.
  • Extra Utilities Quantum Tanks: Store absurd amounts of hot lava for extreme power needs.

With the right set up, you can produce mind-boggling amounts of energy and store it long term in a very compact space. Think stockpiles of diamond blocks, but for energy!

Risks of Energy Compression

While compressing fuels has advantages, there are some risks:

  • Potential for devastating explosions if storage items are damaged or fail.
  • Requires very advanced and expensive machines from end-game mods.
  • Easy to accidentally discharge all your power if not cautious.
  • Can unbalance gameplay by providing almost infinite energy.

As with many ultra-tech Minecraft projects, compressed energy storage rewards planning and forethought. Make sure your compressed energy is well protected!

Storing Charge in Items

Some key tools, weapons, and items in Minecraft can hold electric charge as energy:

  • Mekanism Jetpack/Gas Mask: Build up charge which is drained during flight or oxygen generation.
  • IndustrialCraft Tools: Chainsaw, mining drill etc use EU charge.
  • Thermal Series Tools: RF-powered tools from Thermal Expansion and related mods.
  • Draconic Evolution Armor and Tools: Items store millions of RF for massive feats.

To charge energy items, place them in RF generators/chargers:

  • Input fuel like lava or coal to produce RF.
  • Configure generator to transfer RF into the item.
  • Check item tooltip to see stored charge increasing.
  • Remove item when fully charged.

Now these charged up tools and items can be used on demand for mobility, mining, combat and more. The stored energy gets depleted over time or usage.

Items with electric charge are extremely useful portable energy reservoirs for Minecraft.

Storing Energy in World Mechanics

Aside from tech mods, there are some interesting ways to leverage Minecraft’s base mechanics to store energy:

  • Water Reservoirs: Store water in dams and tanks at high elevations, then let it flow down through turbines to produce kinetic energy as needed.
  • Silo Batteries: Use sand, gravel, etc pushed up into towers to store potential energy, then release to drive clockwork generators when needed.
  • Compressed Sponges: Absorb water into dried sponges for compact hydration storage to be squeezed out later.
  • Dispenser Batteries: Load dispensers with projectiles then trigger them with redstone as needed to fire weaponry.

These methods take some creativity and thought, but allow for unique energy storage without any mods required.

Energy Storage Applications

Why go to the effort of storing energy in Minecraft? What are the practical applications?

  • Powering Machines: Smelters, crafters, factories, and more require steady energy input best provided from storage.
  • Charging Items: Keep a stock of charged tools and weapons ready for use without waiting.
  • Emergency Reserves: Store backup energy to tap into if main grid fails.
  • Transporting Power: Move stored energy around base to different machines.
  • Supporting Large Projects: Massive builds and automation require huge energy reserves.
  • Nighttime/Cave Power: Discharge stored energy when main solar/wind production is low.

Smart use of energy storage helps create self-sustaining bases and smooths out intermittent generation from sources like solar, wind, etc. It enables complex machinery, charged gear, massive projects and more.


There are many great options for storing energy in Minecraft including Redstone Flux, compressed blocks, charged items, stockpiled fuels and more.

Key takeaways include:

  • RF devices like capacitors allow portable electricity storage and transport.
  • Stockpiling fuels/items in containers enables on-demand power reserves.
