Mekanism Extra
by Lost_Myself
Mekanism Extra, a Forge and NeoForge addon for Mekanism, adds ported machines, a Naquadah Reactor, higher-capacity storage and netherite-only ores.
What it does
The mod is a port of Mekanism Evolution to 1.20.1 with further additions. It needs Mekanism, and it runs on client and server, so the server and every player need it. Files are published for Forge and NeoForge across four game versions, 1.20.1, 1.20.4, 1.21 and 1.21.1, with 1.20.1-1.5.0 as the latest Forge file and 1.21.1-1.4.1 as the latest NeoForge file. The code is released under the MIT License and is open source.
Part of the content comes from Mekanism Matter, changed by the author. Factories were added in later builds and gained more slots and stacks, with an upgrade that lets them process up to 64 items at once. The Naquadah Reactor is a large multiblock power source that takes three fuel types as reactants. Configuration is edited in the mekanism extras.toml file inside the MekanismExtras folder. Mekanism Extra is required by MekanismExtrasPlus.
Key features
Naquadah Reactor
A multiblock reactor with a layout close to a large power plant, fed with fuel recipes built from uranium and a second element.
Naquadah ore generation
Naquadah ore spawns near the Overworld bedrock, one cluster per chunk with up to four ores per cluster.
Netherite-only mining
Naquadah ore, its block and its raw block all require a netherite tool to dig.
Bins, cubes and tanks
Absolute, Supreme, Cosmic and Infinite tiers of bins, energy cubes, fluid tanks and chemical tanks raise storage well above Mekanism's own tiers.
Factory upgrade
A new upgrade lets factories handle up to 64 items at once, with more slots and stacks than before.

Use cases
Late-game power and storage
Players who have reached Mekanism's upper tiers can use the larger bins and energy cubes to hold bulk materials and power.
Reactor-based power
The Naquadah Reactor gives a second large power source built around its fuel recipes.
Who it’s for: Players who already run Mekanism and want larger storage tiers, extra factories and a reactor, along with server owners who add these to a modpack.
How it compares
Mekanism: TrashCube is an open source Forge and NeoForge addon for 1.20.1 – 1.21.1 under the MIT License, and it runs on client and server. Mekanism:MoreCapacity is open source under the MIT License for the same loaders and versions, but it is server-side only, so players join without installing it.
