What's the point of producing fuel gas in such a costly way? Just for fun?🙂

Late game you can make diesel via co2 and trade it for gold, that gold can be used in microchip production or traded for uranium for nuclear or for many other things like bauxite for aluminium. Lots of options using waste products.

In the current update, Fuel Gas can be obtained in huge volumes for any purpose simply by selling dirt during ore mining or terraforming — no need to wait for cheap hydrogen from FBR 🙂

Yes, it can but this is a much more long term solution since eventually you will run out of dirt to trade, whilst this uses co2 from all the exhaust you make from trash, smelting and co2 from production of aluminium so it's always there and uses a waste product and it is meant for late game with all the late game tech whilst the dirt solution can be used when this is not available so early-mid game and this can be used late or super late game to provide a solid and constant amount of gold for your factory.

The supply of dirt will never truly run out, since your population constantly produces waste that can be cheaply converted into dirt using mid-game technologies. Well, unless you somehow run out of rock — but that’s hard to imagine, as you can keep digging endlessly deep! 🙂

Pretty sure, all the exhaust you make will give you more gold than the bio-mass they make made into dirt then fuel gas since the settlment makes very little bio-mass whilst you make a ton of exhaust so that means more diesel/ gold from that exhaust and late game you will have that hydrogen available.

Well, there’s also slag and sulfur, both of which can be sold for sludge — and from sludge, you can get fuel gas using two cheap conversion methods.

Yes, that's true but slag is production is lower because of recycling and with sulphur production being nerfed you have less spare so even if you trade it you will have a lot amount of diesel but you could use those methods and this co2 plant to ensure you always have enough diesel to cover both general needs and gold needs.

I have a blueprint where 750 per minute of fuel gas is simply burned into the atmosphere. That could’ve been 500 diesel instead 😂
