Beyond These Stars Coal — Fix Your Soot Shortage Fast

Why Beyond These Stars Coal Keeps Your Colony Alive

If your settlement on Kewa has stalled because half your production buildings are sitting idle waiting on fuel, you've hit the same wall many new players do. In Beyond These Stars, coal and its byproduct soot are the quiet bottleneck that decides whether your Peeps thrive or freeze in place. Unlike lumber or stone, you can't just plant more of it — you have to engineer the supply chain deliberately.

This guide breaks down where coal and soot actually come from, which buildings consume them, and the workarounds the community has found for the notorious early-game soot drought. Whether you're fresh off the tutorial or already terraforming your second district, you'll walk away knowing exactly how to keep the burners fed without drowning in surplus iron and copper.

One note up front: Beyond These Stars launched in 1.0 on October 16, 2026, and balance values are still shifting with hotfixes. Treat any specific number here as a starting point, not gospel.

Coal vs. Soot: Understanding the Two Resources

New players often use "coal" and "soot" interchangeably, but the game treats them as related yet distinct. Coal is the raw fuel you mine or produce; soot is the residue that accumulates as a byproduct of burning and smelting. Several mid-game buildings demand soot directly, which is why a colony can have plenty of ore and still choke on a soot shortage.

Here's the practical distinction:

The key insight: soot is a byproduct, not a primary output. You can't build a "soot factory" — you generate it by running the very buildings that also flood you with metal.

How the Soot Shortage Became the Community's Biggest Complaint

On the Steam community hub, one of the most active discussion threads is simply titled "Not Enough Soot." The original poster describes spending large stretches of the game just waiting for soot to trickle in, noting that many buildings need it while few of the buildings they want to construct actually produce it. Their workaround — running burners and ore smelters hard — creates a second problem: a flood of surplus iron and copper.

Community reports suggest this is a reversal from the pre-release demo, where soot was reportedly overproduced. The 1.0 balance pass swung the pendulum the other way. That's a useful lesson: if a guide written during the demo tells you soot is plentiful, it's outdated.

A few practical takeaways from player experience:

• Don't over-build smelters just for soot. You'll cap out on metal storage and waste Peep labor.
• Bank soot before you need it. Queue a burner run ahead of any construction push that requires soot-heavy buildings.
• Watch for chemical unlocks. Multiple players note that the soot crunch eases once you reach the chemical production tier, so prioritize that tech line if soot is stalling you.

Which Buildings Actually Consume Coal and Soot

Knowing your consumers helps you plan production ratios instead of guessing. Based on the game's building descriptions and player discussion, here's a rough map of the fuel economy:

That last row matters more than it looks. Players have asked on Steam whether huts can be upgraded to houses without bulldozing, and the answer at launch appears to be no — you rebuild manually. Every rebuild is another soot sink, so plan your housing layout to minimize teardowns.

Step-by-Step: Building a Stable Coal and Soot Supply

Here's a repeatable workflow for keeping fuel flowing without wrecking your metal economy.

Step 1: Map Your Deposits Before You Build

Before placing a single burner, survey the terrain around your starting green patch. Coal deposits are finite on Kewa's back, and the land is fragile — over-mining shrinks your habitat. Note deposit locations and plan roads to minimize Peep travel time, since long hauls quietly eat your labor budget.

Step 2: Pair Burners With Storage, Not Just Smelters

Run burners for soot, but build storage adjacent so surplus soot banks instead of halting production. Avoid stacking ore smelters purely for soot — that's the trap the "Not Enough Soot" thread describes.

Step 3: Time Your Construction Pushes

Batch soot-heavy construction (housing, advanced buildings) right after a burner cycle rather than spreading demand thin across the whole game. This smooths the feast-or-famine curve.

Step 4: Use Pollution as a Resource — Carefully

One reviewer noted that pollution can be repurposed as a resource, and that this conversion happens quite early. Lean into it, but don't rely on it as a soot substitute; it solves a different problem (waste management) than fuel supply.

Step 5: Chase the Chemical Tech Tier

Community consensus points to chemicals as the point where soot pressure finally releases. If you're stuck, redirect research toward that branch instead of grinding burners.

Terraforming and Fuel: The Hidden Connection

Coal isn't the only thing you'll reshape on Kewa. The terraforming system lets you dig canals, add topsoil, and plant forests — and forests do double duty. Trees provide a renewable raw material stream and help spread atmosphere, which supports city expansion.

That matters for fuel because a larger, healthier habitat means more room for production districts and more Peeps to staff them. A common mistake is tunneling all effort into burners while neglecting the ecosystem; when the habitat shrinks, your fuel infrastructure loses the land it sits on.

For a full walkthrough of these systems, the official Beyond These Stars Beginner's Guide on Steam covers building, Peep care, terraforming, and perks — a solid companion to this resource-focused article.

Common Coal and Soot Mistakes to Avoid

Even experienced colony-sim players stumble on a few specific traps in Beyond These Stars:

• Over-smelting for soot. You'll cap metal storage and stall smelters, wasting coal in the process.
• Ignoring Kewa's mood. Outposts and expansion depend on your relationship with the Space Whale. If Kewa decides to leave a system, your outpost-based resource plans evaporate — so don't put all your coal eggs in an off-world basket.
• Bulldozing housing carelessly. Since huts don't upgrade in place at launch, every rebuild costs soot. Design housing clusters you won't need to tear down.
• Skipping the tutorial checkbox. A hotfix specifically addressed the tutorial toggle resetting when you visit Difficulty Settings — a small but real quality-of-life fix worth knowing about.
• Assuming difficulty fixes balance. One critical reviewer argued that higher difficulty doesn't meaningfully change expansion ease, so don't expect a difficulty bump to solve a supply-chain design problem.
