What is Coal Liquefaction in Frostpunk 2?

Coal Liquefaction in Frostpunk 2 is a process that can be researched to create Oil directly from Coal and other resources. It is a smart workaround that is necessary to ensure the city’s survival and can help players focus on other activities once it is successfully implemented. However, the solution that is present in the Idea Tree comes in two different types with two different cornerstones - Adaptation and Progress.

How to unlock Coal Liquefaction in Frostpunk 2?

Coal Liquefaction in Frostpunk 2 can be unlocked after upgrading the generator for the first time by utilizing the Heating category of the Idea Tree. While you can choose to research both the Carrion Coal Liquefactor and Pressurized Coal Liquefactor, it is better to take up only one side since each costs a whopping 100 Heatstamps.

Once it is unlocked, the Liquefactor can be built in the Industrial District. Such a massive structure has its upkeep costs and players can choose to scale it up or down depending on the needs of the city. You can control this by using the slider that pops up when clicking on the Industrial District. Once scaled down, it will consume less resources but also produce a smaller amount of Oil.

Why should you use Coal Liquefaction in Frostpunk 2?

The Coal Liquefaction research in Frostpunk 2 is a great mid-game way to help the city defend itself against the Cold while also enabling expansions. However, there are a few items that need to be considered before choosing either the Carrion Coal Liquefactor or the Pressurized Coal Liquefactor research. Here is a quick overview of both paths alongside a short description:

Research Name	Building Cost	Cornerstone	Output	Upkeep Cost
Carrion Coal Liquefactor	200 Heatstamps, 100 Prefabs, and 1 Core	Adaptation	60 Coal to 80 Oil. Increases Disease in the city.	Requires 400 Workforce and 20 Material
Pressurized Coal Liquefactor	200 Heatstamps, 100 Prefabs, and 1 Core	Progress	100 Coal to 80 Oil. Increases Squalor in the city.	Requires 300 Workforce and 40 Material

It is best to research the one that complies with the vision for your city. If you are more capable of pumping out Materials and subduing Squalor in the city, the progressive route is the better way. Alternatively, if you can provide more treatment and healthcare to defeat the onset of Disease, the Adaptation research might be the path to take.

One of the best ways to balance the output and upkeep for this process is by building a single Goods Factory alongside the Liquefactor. This can help the city meet the massive upkeep demands without creating any shortage or obstacles.

It is important to note that Coal Liquefaction in Frostpunk 2 is an expensive process that eats up a lot of resources starting from the research itself. However, it is a great upgrade since the generators can output more heat and work efficiently with Oil instead of Coal.

In case you opt to upgrade the generator to use only Oil, Liquefactors become essential as the abundant Coal becomes useless without them. This can ensure that the generators complete their work without requiring constant supervision.

A niche workaround to get more Coal stockpiles, other than scavenging, is to create Charcoal facilities. These can be used after researching Sawmills that can turn Material into Coal, providing a healthy supply to the Liquefactors. However, this is going to be costly, so it is best to gauge the resources of the city before committing to it.
