In Starfield, look for Alkanes (HnCn) on planets and moons such as Kreet in Narion and several bodies in Ixyll. Scan the planet before landing, then gather a deposit or build an outpost gas extractor for a repeatable supply. You can also check resource vendors, but their stock varies.
What Alkanes are used for
Alkanes is an uncommon inorganic resource, shown in-game as HnCn. The Starfield Wiki resource entry lists Monopropellant as a crafting use and Mixology 1 as a research requirement.

How to gather Alkanes
Find a surface deposit
- Open the system and planet views and select a world listed with Alkanes. Kreet in Narion is one option; Ixyll I, Ixyll II, and Ixyll VI-C are others.
- Scan the planet and choose a landing region with the resource. After landing, use the scanner to look for resource areas and approach a deposit to gather it.
Bethesda’s resource-gathering guidance explains that surface resources can be gathered at visible points and that outposts can extract and store resources.
Set up an outpost for recurring supply
Alkanes is categorized as a gas resource, and the listed outpost tool is a gas extractor. Place an outpost on an Alkanes deposit, then provide the extractor with the required power and storage. This takes more setup than gathering a small amount, but supports ongoing production while the outpost operates.

Rank #3
- TELL YOUR STORY - In Starfield the most important story is the one you tell with your character. Start your journey by customizing your appearance and deciding your Background and Traits. Will you be an experienced explorer, a charming diplomat, a stealthy cyber runner, or something else entirely? The choice is yours. Decide who you will be and what you will become.
- EXPLORE OUTER SPACE - Venture through the stars and explore more than 1000 planets. Navigate bustling cities, explore dangerous bases, and traverse wild landscapes. Meet and recruit a memorable cast of characters, join in the adventures of various factions, and embark on quests across the Settled Systems. A new story or experience is always waiting to be discovered.
- CAPTAIN THE SHIP OF YOUR DREAMS - Pilot and command the ship of your dreams. Personalize the look of your ship, modify critical systems including weapons and shields, and assign crew members to provide unique bonuses. In deep space you will engage in high-stakes dogfights, encounter random missions, dock at star stations, and even board and commandeer enemy ships to add to your collection.
- DISCOVER, COLLECT, BUILD - Explore planets and discover the fauna, flora, and resources needed to craft everything from medicine and food to equipment and weapons. Build outposts and hire a crew to passively extract materials and establish cargo links to transfer resources between them. Invest these raw materials into research projects to unlock unique crafting recipes.
- LOCK AND LOAD - Space can be a dangerous place. A refined combat system gives you the tools to deal with any situation. Whether you prefer long-range rifles, laser weapons, or demolitions, each weapon type can be modified to complement your playstyle. Zero G environments add a chaotic spectacle to combat, while boost packs give players freedom to maneuver like never before.
Which method should you use?
| Method | Best fit | Trade-off |
|---|---|---|
| Gather a surface deposit | A small amount when you are already visiting a listed world | Requires scanning and finding a deposit at a suitable landing area |
| Outpost gas extractor | A supply you want to produce repeatedly | Requires an outpost, power, storage, and a deposit |
| Buy from a vendor | A convenient top-up if a shop has Alkanes in stock | Availability varies, so a listed shop may not have it |
The available sources do not establish a measured time-to-gather or guaranteed vendor inventory, so no method is universally fastest.
