Hydrogen Line Farming Guide

Read This First: Farming Before Angstrom Opens

Angstrom, the first full universe, opens Friday, November 13, 2026, at 3pm UK, free in your browser, and everyone starts together. An open beta has been running ahead of the full release, and the beta universe stays open after launch. No verified seller market for Hydrogen Line was found during MMODude’s November 2026 review, so do not pay a third party for Hydrogen Line gold or items. Everything below comes from the official site and the launch material — no production rates, prices or trade fees have been published.

Farming in Hydrogen Line is not a mob grind. It is production plus raiding: mines and colonies produce around the clock, fleets raid rivals for what their mines made, and battle wreckage is harvested and grown into moons. Upgrades run while you sleep, so the farm is a schedule you set, not hours you sit. That is the first thing to understand about this economy — it rewards the player who plans the queue, not the player who plays the longest session.

Hydrogen is the bottleneck to plan around. The official site says it plainly: hydrogen is the commonest thing in the universe and still the thing every colony runs short of, and every fleet burns it. Farm metal and silicon to build, but farm hydrogen to move — a fleet with no fuel is a fleet that stays home. The companion Hydrogen Line Leveling Guide covers the progression side — the first planet, the tech tree, colonies, fleets and alliances. This guide covers the money side: the three resources, The Exchange, raiding, wreckage, and how to keep the hydrogen flowing.

The Three Resources: Metal, Silicon, Hydrogen

Your homeworld starts with all three producers: a Metal Mine, a Silicon Mine and a Hydrogen Extractor, and all three need power, so a Solar Plant comes early, per the official site. Metal and silicon feed buildings, ships and research; hydrogen feeds every flight. Balance the three against what you are building next, not against each other in the abstract — a planet that is all metal and no hydrogen can build a fleet it cannot fly, and a planet that is all hydrogen and no metal can fly a fleet it cannot replace.

Resource	Produced by	Spent on	The rule
Metal	Metal Mine	Buildings, ships, research	The building currency — push it when you are building
Silicon	Silicon Mine	Buildings, ships, research	The building currency — push it when you are researching
Hydrogen	Hydrogen Extractor	Every flight	The movement currency — the bottleneck, always
Power	Solar Plant	All three mines	The constraint — mines without power do not produce

The power constraint is the first farming lesson. All three mines need power, so a Solar Plant comes early — and a planet that pushes mines without the power to run them is a planet that spent metal on mines that sit idle. The order matters: power first, then the mine that feeds what you are building next. A new player’s first mistake is usually a mine built before the plant that powers it; the second mistake is usually a third mine built while the first two are still waiting for power.

The second lesson is that the three resources are not interchangeable. Metal and silicon are the building currencies, and they are spent in lumps — a building, a ship, a research project. Hydrogen is the movement currency, and it is spent in a steady drain — every flight, every raid, every scouting run. A lump-sum currency can be stockpiled; a drain currency has to be managed. The player who treats hydrogen like metal — something to accumulate and then spend in one big purchase — will find the tank empty on the day the alliance lands four fleets on one target.

Production: Mines, Power and Queues

Production in Hydrogen Line is a schedule, not a session. Upgrades take minutes at first and most of a day later, and they carry on while you are asleep, per the official site. That is the farming economy in one sentence: the mines produce around the clock, the upgrades finish while you are not at the keyboard, and the skill is in never letting a finished upgrade sit idle while you sleep. A player who queues the next upgrade before bed produces more than a player who queues it in the morning, because the second player’s planet sat idle all night.

The queue is the farm. Keep the lab working and the dock busy, and do not let a finished upgrade sit idle — the same rule the leveling guide gives for progression applies double for production, because production is the thing that compounds. A mine upgraded tonight produces more tomorrow, and the extra production funds the next upgrade, and the next upgrade funds the one after that. The compounding is slow at first — minutes-long upgrades, small gains — and it accelerates as the upgrades stretch to most of a day and the gains get bigger. The players who compound from day one are the players with twice the production by the end of the first week.

Two habits follow from the queue economy. First, set the long jobs before bed. An upgrade that takes most of a day is an overnight job, and an overnight job is free growth — the planet works while you sleep, and you wake up to a bigger mine. Second, match the mine to the build. If the next building needs metal, push the Metal Mine; if the next research needs silicon, push the Silicon Mine; if the next fleet needs hydrogen, push the Extractor. The mines are not a set to be kept level — they are a set to be pointed at the next thing you are building.

No production rates, upgrade costs, or research times have been published. The developers have not said how much metal a mine produces per hour, what an upgrade costs, or how long a technology takes to research, and this guide does not invent those numbers. The shape is documented — minutes at first, most of a day later, running while you sleep — but the numbers are not. Plan around the shape (queue before bed, power before mines, never idle) rather than around a rate nobody has published.

Colonies Multiply Everything

Colonies multiply the whole picture. A Colony Ship settles a second world — one of 15 planet kinds, from deserts to gas giants — and each new colony adds its own mines to the empire. A second colony doubles the mines and the hydrogen income, so the colony race is the first real farming milestone as well as the first leveling milestone: the player with two worlds out-produces the player with one, and the player with three worlds out-produces the player with two.

The multiplication is the compounding made concrete. One planet’s mines produce a certain amount; two planets’ mines produce twice that, and the extra production funds the third colony faster than the second colony was funded. The launch carousel describes five galaxies of 499 systems to colonise across, so the long game is more worlds, more mines, and more hydrogen to move fleets between them. That figure comes from the October 18 carousel, not the official site — the site says one galaxy shared by every player — and this guide attributes it as such. Whichever figure is right, the practical point is the same: the map is big, and the empire that keeps settling is the empire that keeps growing.

The 15 planet kinds are the choice that makes the second colony interesting. Deserts to gas giants is the range the official site gives, and it implies — without stating — that different planet kinds suit different things. This guide does not invent a per-kind bonus table, because none has been published. What can be said is that the choice exists, that a settled world is a settled world, and that the right move is to scout before you settle. A colony is a commitment of a Colony Ship and the time to build it; settling the wrong world, or settling a world next to a rival who will raid it, is a mistake that costs days of production.

Rival colonies are not marked for you: the official site says you have to find them, with Espionage Probes or by noticing where fleets come and go. That matters for farming as well as for leveling, because a colony’s mines are only safe if the colony is not found — and a colony that is found is a colony that gets raided. Scout the neighbourhood before you settle, settle where the traffic is thin, and keep a probe or two in the fleet rotation, because a neighbourhood changes and the map you made on day one is out of date by day seven.

The Exchange: Trader, Players, Broker

In-game trading runs through a system called The Exchange. The October 19 launch post shows it directly: “Everything has a price. Trade with the Trader, other players, or the Broker.” Three counterparties, one market — the Trader, fellow players, and the Broker — and the name to look for in game is The Exchange.

That is, in full, what has been published about trading. The launch graphic shows a broker at an exchange window with holographic scales weighing metal, currency, and energy vials, and the caption is the whole mechanic: everything has a price, and there are three ways to pay it. The Trader is presumably the game’s own buyer and seller; other players are the player market; the Broker is the intermediary. This guide does not assign roles beyond those names, because the developers have not published what each counterparty does differently, what the Broker charges, or whether the Trader’s prices are fixed.

Beyond that, nothing about trading is published: no rates, no fees, no price lists and no limits could be verified, and this guide will not invent them. Use The Exchange to cover the resource you are short on and sell the one you have in surplus, and check the actual prices in game on launch day before planning an empire around a trade. The farming logic is the same as in any market: sell the surplus, buy the shortage, and let the market do the matching — but the prices are unknown until launch, and the first week’s prices will be wild, because a launch economy has no history to anchor it.

No Exchange rates, fees, price lists, or limits have been published. This is the single most important unknown in the game’s economy, and this guide states it plainly rather than filling it with a guess. Do not trust any guide that quotes an Exchange price, fee, or rate before launch — the only published facts are the name, the three counterparties, and the tagline. Check the live Exchange on launch day.

Raiding and the Frigate

Raiding is the second income stream, and it is the one that does not wait for a mine to finish upgrading. The launch carousel lists raiding foes to steal resources, and the official site’s ship list backs it up: the Frigate is built for catching cargo traffic, with a hold to carry home what it takes. A raid that lands is production you did not have to wait for — and a raid against you is production you lose.

The Frigate is the raiding ship, and it deserves its own paragraph because it is the ship that turns a fight into income. It is built for catching cargo traffic, which means it hunts the ships that carry resources between planets — the Transports, the slow haulers, the cargo runs that keep an empire fed. And it has a hold to carry home what it takes, which means the raid does not only destroy the target’s cargo — it brings the cargo home. A Frigate fleet that catches a cargo run has farmed the target’s production without building a mine.

The counter chain matters for raiding as much as for war. Cruisers have three quick guns against Scouts, transports and probes — which means a Cruiser screen protects cargo traffic, and a Frigate that runs into a Cruiser screen is a Frigate that does not come home. The raiding game is therefore a scouting game first: find the cargo traffic, check its escort, and only then launch. A raid launched blind is a raid that meets the wrong ships, and a raid that meets the wrong ships is a loss of hydrogen as well as a loss of ships — hydrogen spent on a flight that brought nothing home.

The defense side is the mirror image. Your cargo traffic is someone else’s raid target, and your mines’ production is only yours until someone takes it. The official site’s line about rivals watching your fleet coming applies to raiders too: a rival can watch your fleet coming, and the question is whether they are awake. Keep a Cruiser screen on your cargo runs, keep your hydrogen tank from emptying on defense flights, and remember that every raid against you is production you lose — the best defense is a fleet that is already home when the raider arrives.

Wreckage, Collectors and Moons

Every fight leaves something behind. Ships fire in rounds, and the battle report lists what each side brought, what it lost, what was looted, and the wreckage left floating for anyone with a Wreckage Collector. That is the official site’s combat economy in one sentence, and it is the third income stream: the fight is not only about who wins, it is about what the winner — and anyone else with a Collector — can take from the wreckage.

The Wreckage Collector is the ship that harvests it, built at the Dock alongside the warships. A battle’s wreckage is left floating for anyone with a Collector, which means the harvest is not limited to the winner — a third party with a Collector can take wreckage from a fight it did not fight in. That makes the Collector the most opportunistic ship in the game: it does not need to win a battle, it needs to arrive after one. The player who keeps a Collector near a war zone is the player who harvests other people’s fights.

And what is left can become a moon. A moon seed forms in big wreckage. Defend it while it grows, then build up to seven moon buildings on it, from the Mass Driver to the Slip Gate. The moon is the game’s long-term prize: a second base that grows out of a battle, defended while it grows, and built up with as many as seven buildings. The Mass Driver and the Slip Gate are the two buildings the site names — the first and the last of the seven — and the five in between are not named anywhere this guide could read. Do not plan around a building list that has not been published.

The moon mechanic changes how you think about big fights. A big fight is not only a risk — it is a moon seed, and a moon seed is a base. The player who wins a big fight and collects the wreckage is the player who grows a moon; the player who loses a big fight has still created a moon seed that someone else can defend and grow. The leveling guide covers moons as progression; the farming point is that a moon is an income asset as well as a base — seven buildings’ worth of whatever the moon buildings do, grown out of wreckage that would otherwise have drifted away. Send the Collector, defend the seed, and build the moon.

Pirates and Trader Convoys

Temporary pirates and trader convoys also appear in open space, per the launch carousel — moving targets worth watching for. They are the only part of the game that is explicitly temporary: they appear, they can be caught, and they go away. A trader convoy is a cargo run that is not yours and not a rival’s — a moving pile of resources with an escort, waiting to be raided. A pirate is a moving threat that is also a moving target — a fight that pays, if you can catch it.

No spawn rates, no rewards, and no mechanics have been published for pirates or convoys beyond their existence in the carousel. This guide does not invent them. What can be said is structural: they are moving targets in open space, which means they reward the player who watches the starmap and the player whose fleet has hydrogen to spare for a chase. A convoy that appears while your tank is empty is a convoy you watch sail past. A pirate that appears while your fleet is home is a pirate you cannot catch.

The practical advice is to keep a fast fleet ready and a hydrogen reserve for it. The Frigate is the raiding ship, the Interceptor is the fast skirmisher, and the two together are a convoy-hunting pair: the Interceptor catches what runs, the Frigate carries home what it takes. Keep them fueled, keep them crewed, and watch the open space — because the temporary targets are the ones that pay the players who are ready, and they do not wait for the players who are not.

Managing the Hydrogen Bottleneck

Hydrogen is the bottleneck, and managing it is the farming skill that decides whether the rest of the farm works. The official site says it plainly: hydrogen is the commonest thing in the universe and still the thing every colony runs short of, and every fleet burns it. Every colony runs short of it because every fleet burns it, and every flight is a spend from a budget that refills slowly. The management rules follow from that one fact.

First, keep the Extractor working. The Hydrogen Extractor is the third mine, and it is the one that is easiest to neglect, because its product is not spent in lumps like metal and silicon — it is spent in a steady drain, and a drain is easy to ignore until the tank is empty. Push the Extractor when you are planning flights, not after you have already launched them. A fleet that is already flying cannot wait for an upgrade to finish.

Second, spend hydrogen like it is the scarcest thing you own — because, per the official site, it is. Do not fly a fleet to scout a system you have already probed. Do not raid a target whose cargo is worth less than the hydrogen the flight burns. Do not send a Frigate after a convoy that is already gone. Every flight has a hydrogen price, and the price has to be less than the flight’s return, or the flight is a loss even if it wins the fight.

Third, keep a reserve. The alliance landing is the moment the reserve matters: four fleets launch at different times so they land together, and the fleet that cannot launch on time is the fleet that does not land with the others. A player who spends their hydrogen down to zero on a raid the day before an alliance operation is a player who watches the operation happen without them. Keep enough in the tank for the landing, and treat the reserve as untouchable until the operation is over.

Fourth, remember that hydrogen is visible. A fleet burning hydrogen shows on the line long before anyone sees it, which means your spending is a signal as well as a cost. A big burn tells the galaxy you are moving, and a big burn tells the galaxy where you are going. Spend quietly when you can — small flights, short hops, no wasted burns — and spend loudly only when the loudness is the point, because a fleet that is meant to be seen is a fleet that is meant to deter.

Highscores and the Long Game

The launch carousel ends on highscores, with the tagline “Keep growing. Everyone else is.” That is the long game in one line: the galaxy is shared, the growth is visible, and the player who stops growing falls behind the players who do not. No highscore categories have been published — the carousel does not say whether the board ranks empires by size, by fleet, by colonies, or by something else — and this guide does not invent them. What can be said is that the board exists, that it is public, and that it is the game’s scoreboard.

The long game in Hydrogen Line is the compounding game: more worlds, more mines, more hydrogen, more fleets, more moons. The compounding is slow at first and accelerates as the colonies multiply, and the players who compound from day one are the players at the top of the board by the end of the first month. The highscore is not a prize to be won in a week — it is a record of who kept growing, and the tagline is the warning: everyone else is.

One more thing the official site documents that belongs in the long game: every big change goes to a player vote before it goes live. The game is run by two developers, and the players vote on the big changes. That means the economy you are farming in is an economy the players can change — a vote can move a rate, a cost, or a rule, and the farm that works today can work differently after a vote. Watch the votes, join the Discord, and be ready for the economy to move. A launch-watch guide cannot predict the votes; it can only tell you they exist.

Trading Without Prices: How to Use The Exchange on Day One

The Exchange is the one part of Hydrogen Line’s economy where the launch-watch guide has to be most careful, because it is also the part new players will ask about first. Everything has a price, the launch post says, and there are three counterparties — the Trader, other players, and the Broker. But no rates, no fees, no price lists and no limits have been published, so the honest answer to “what should I trade?” is: find out on launch day, and until then, trade on principles rather than prices.

The first principle is the surplus principle. Sell what you have too much of, and buy what you are short of. A planet that has pushed its Metal Mine hard will have metal to spare and hydrogen to miss; a planet that has pushed its Extractor will have hydrogen to spare and metal to miss. The Exchange exists to fix exactly that mismatch, and the trade is worth making whenever the resource you are selling is worth less to you than the resource you are buying. You do not need a price list to know that a stockpile of metal you cannot spend is worth less than the hydrogen that lets your fleet fly.

The second principle is the three-counterparty principle. The Trader, other players, and the Broker are three different ways to make the same trade, and they will not all give you the same deal. The Trader is presumably the game’s own buyer and seller — always there, always trading, probably at a fixed or slowly moving price. Other players are the player market — better prices when someone is in a hurry, worse prices when no one is selling what you need. The Broker is the intermediary — and an intermediary usually charges for the service, though no fee has been published. The smart move on day one is to check all three before you trade, because the best price for the same resource may be at a different counterparty than the one you checked first.

The third principle is the launch-week principle. A launch economy has no history, so the first week’s prices will be wild. The first sellers set the prices, the first buyers set the demand, and both will be wrong by the end of the week as the economy finds its level. Do not build your empire around a price you saw on day one. Trade small, trade often, and let the market teach you what things are worth — because the market on day seven will be a different market from the one on day one, and the player who traded small all week will have learned the prices while the player who bet everything on day one is still holding the bag.

The fourth principle is the one this guide repeats everywhere: do not trust a price you read in a guide. The only published facts about The Exchange are the name, the three counterparties, and the tagline. Any guide that quotes an Exchange price, fee, or rate before launch is quoting a guess. Check the live Exchange on launch day, check it again the next day, and keep checking until the prices settle — because in a game where every big change goes to a player vote, the Exchange itself can change, and the prices you learn this week may not be the prices next month.

Your Launch-Week Farming Plan

Angstrom opens Friday, November 13, 2026, at 3pm UK, and everyone starts together. That sentence is the whole launch race: a single start time, a single galaxy, and every empire beginning on the same day. The players who produce the most in the first week will not be the ones who play the most hours — they will be the ones whose queues never sit idle, whose power comes before their mines, and whose second colony lands before their neighbours’ second colony does.

Before launch: read the site, join the community, and be ready at 3pm UK. The official site is the whole manual — three mines, a Solar Plant, a Technology Lab, a Dock, and a Colony Ship — and the launch graphic is the whole schedule. Join the Discord, the Reddit, or the X account linked from the official site, because the two-developer team and the player-vote system mean the community is where changes are discussed before they go live. If you played the beta, remember that the beta universe stays open after launch — your beta progress is not the launch, and the launch is a fresh start.

Day one: mines, power, lab, dock — in that order. Start with the three mines, get the Solar Plant up early, and open the Technology Lab and the Dock as soon as you can. Keep the lab working and the dock busy from the first hour. Do not spend your first day building ships before your mines are running — a fleet with no economy behind it is a fleet that cannot be replaced. Queue the long job before bed on the first night, because the first night’s queue is the first day’s growth.

Days two to four: push the mines, and build the first raiding ships. Push the mine that feeds what you are building next, keep the lab researching, and build a Frigate or two — the raiding ship is the second income stream, and the first week is when cargo traffic is busiest, because everyone is building. Start probing the systems around your homeworld, because the colony decision is coming and the scouting should be done before it, not after.

First weekend: settle the second colony. The colony race is the first real farming milestone, and the player with two worlds out-produces the player with one. Scout before you settle, settle before your neighbours do. A second colony doubles the mines and the hydrogen income, and the doubling is the compounding that separates the first week’s leaders from everyone else.

First week: check The Exchange, and do not plan around it. The Exchange will be live, and the prices will be wild, because a launch economy has no history to anchor it. Use it to cover the resource you are short on and sell the one you have in surplus — but do not build your empire around a price you saw on day one, because the price on day seven will be different. The Exchange is a tool, not a plan.

After the first week: reassess from the live game. By then the launch will have happened, the first balance changes will have landed, and the community will have measured the things nobody has published — production rates, research times, ship costs, Exchange prices. This guide will be out of date the moment those numbers exist, and that is fine: a launch-watch guide’s job is to get you to launch day with a sound plan, not to pretend the numbers were known all along. Check the official site before planning around any figure you read here.

Common Mistakes

Building mines without the Solar Plant power they need, then wondering why production stalls. Power first, then the mine that feeds what you are building next.
Spending hydrogen on flights you do not need when every colony already runs short of it. Every flight has a hydrogen price, and the price has to be less than the flight’s return.
Leaving wreckage uncollected after a fight instead of sending a Wreckage Collector. A battle’s wreckage is left floating for anyone with a Collector — including your rivals.
Planning trades around prices, rates or fees that have never been published for The Exchange. Check the live Exchange on launch day before planning an empire around a trade.
Settling a second world without scouting, when rival colonies have to be found first. A colony next to a rival’s fleet is a colony that gets raided.
Letting upgrades sit finished and idle while you are asleep, when they run on their own. Queue the long job before bed.
Building one ship type when each class is tuned against particular targets. A fleet is a set of answers, and the Frigate that meets a Cruiser screen does not come home.
Paying a third party for Hydrogen Line gold or items when no verified seller market exists. No Hydrogen Line listing was verified on any checked marketplace during MMODude’s November 2026 review.

Frequently Asked Questions

What is The Exchange in Hydrogen Line?

The in-game trading system. The launch post says: “Everything has a price. Trade with the Trader, other players, or the Broker.” No rates, fees or price lists have been published.

What resource runs out first in Hydrogen Line?

Hydrogen, per the official site: it is the commonest thing in the universe and still the thing every colony runs short of, and every fleet burns it.

How do you get resources without mining in Hydrogen Line?

By raiding rivals to steal resources, and by collecting battle wreckage with a Wreckage Collector. Big wreckage can also grow a moon seed into a moon with up to seven buildings.

When does Hydrogen Line fully release?

November 13, 2026, at 3pm UK, when Angstrom, the first full universe, opens. It is free in your browser, and everyone starts together.

How many galaxies are there in Hydrogen Line?

The official site says one galaxy shared by every player. The October 18 launch carousel describes colonising across five galaxies of 499 systems — that figure comes from the carousel, not the official site, and this guide attributes it as such.

Can you buy Hydrogen Line gold or items?

Not from a verified seller. No Hydrogen Line listing was verified on any checked marketplace during MMODude’s November 2026 review, so do not pay a third party for Hydrogen Line gold or items.
