The cost of rocket fuel is a significant factor in the overall cost of launching payloads into space. The type of rocket fuel, its volume, and density all play a role in determining the overall cost. For instance, liquid hydrogen (LH2) is priced at approximately $6.1 per kilogram, while RP-1, a refined form of kerosene, is more cost-effective at around $2.3 per kilogram. SpaceX's Falcon 9 rocket burns around $200,000-$300,000 in propellant, and with a payload capacity of 16,000 kg, this equates to about $20/kg. The price of rocket fuel is influenced by production methods, refinement, and market dynamics, and it is an important consideration in the economics of space missions.

What You'll Learn
Liquid hydrogen (LH2) costs $6.1 per kg
The cost of rocket fuel varies depending on the type of fuel used. Liquid hydrogen (LH2) costs $6.1 per kg according to moving average US defense prices, though standard prices by the Defense Working Capital Fund indicate a much higher price of $30.5/kg. LH2 is a popular choice for rocket fuel due to its high performance and relatively low cost compared to other options. It is also more efficient in terms of storage and requires less space compared to gaseous hydrogen (GH2) systems.
LH2 fueling systems offer a significant cost advantage, with an average of 40% less expense than GH2 systems while maintaining similar performance. This is because LH2 storage is more cost-effective per kilogram. Additionally, LH2 systems have fewer components, resulting in fewer potential failures and lower maintenance costs. The heat exchanger process in LH2 systems also eliminates the need for mechanical refrigeration, further reducing utility and maintenance expenses.
However, it is important to consider the losses associated with the LH2 supply transfer process, which can result in a 15% product loss. There are also transportation and storage costs to factor in, as hydrogen liquefaction requires a significant amount of energy, contributing to the overall per-kilogram pricing. Despite these considerations, LH2 remains a cost-effective option for rocket fuel, especially when compared to other propellants such as solids, which cost around $5/kg, or hydrazine, which can reach prices of up to $75.8/kg.
The overall cost of rocket fuel is just one factor in the economics of space exploration and satellite launches. While fuel prices may vary, the dominant costs in the space industry tend to come from hardware and personnel expenses, with launch costs heavily influenced by salaries rather than fuel prices.

RP-1 costs $2.3 per kg
RP-1 is a type of rocket fuel that costs $2.3 per kg. It is a hydrocarbon rocket fuel that has been used in the first-stage boosters of many rockets, including the Electron, Soyuz, Zenit, Delta I-III, Atlas, Falcon, Antares, and Tronador II. RP-1 is also known as rocket propellant 1 and is a refined form of kerosene. It is cheaper than other rocket fuels such as LH2, which costs around $6.1 per kilogram, and is a more standard, widely distributed petroleum product.
The cost of rocket fuel can vary depending on the type of fuel and the launch vehicle. For example, the Indian Space Research Organization (ISRO) is developing an RP-1-fueled engine for its future rockets, while SpaceX has used sub-cooled RP-1 for its Falcon 9 rocket. The price of rocket fuel may also be influenced by supply and demand, as the launch vehicle industry is relatively small compared to other consumers of petroleum.
In addition to RP-1, other types of rocket fuels include LOX, CH4, solids, and hybrid propellants. LOX, or liquid oxygen, is a common oxidizer used in rockets and costs around $0.27 per kg. CH4, or methane, is another type of rocket fuel that is used by the Starship and is purchased in volume at an estimated cost of $500k per launch. Solids are a less expensive option at around $5 per kg as of 2008, while hybrid propellants can be significantly more expensive.
The cost of rocket fuel is just one factor in the overall launch cost of a rocket. According to Henry Spencer, a founding member of the Canadian Space Society, "fuel is cheap – it’s the hardware and people that cost you." The average launch cost is around $450 million, which includes salaries and other expenses. Therefore, the few hundred thousand dollars for propellant are considered relatively low in the space industry.

CH4 costs $8.8 per kg
The cost of rocket fuel varies depending on its type. According to moving average US defense prices, LH2 costs around $6.1 per kilogram, though standard prices by the Defense Working Capital Fund indicate a much higher price of $30.5 per kg. RP-1 presents a cheaper option at $2.3 per kg. CH4 costs $8.8 per kg, while LOX comes in at $0.27 per kg. Solids cost around $5 per kg as of 2008, while hybrid propellants are significantly more expensive. HTPB costs $8 per kg, and hydrogen peroxide costs $10.36 per kg. Hydrazine tops the chart at up to $75.8 per kg.
The cost of rocket fuel is just a small fraction of the total launch cost. The overall budget for one launch can reach up to $1.5 billion, while the propellant cost is only about $4 million.
The price of rocket fuel also depends on the launch system being used. For instance, the Falcon 9 burns somewhere around $200,000-$300,000 in propellant, and for non-expendable launches, it puts about 16,000 kg into orbit, resulting in a cost of about $20 per kg. On the other hand, the Starship burns cheaper methane fuel, and the propellant cost is estimated at about $500,000 per launch when purchased in volume.
A photon rocket, which is a hypothetical concept, would require far less fuel to lift a payload. It could theoretically lift 1kg of payload with just 0.03 grams of fuel. However, this would require an extremely powerful laser consuming an enormous amount of power.
In conclusion, while CH4 costs $8.8 per kg, the overall cost of rocket fuel depends on various factors, including the type of fuel, the launch system, and the total launch budget.

LOX costs $0.27 per kg
The cost of rocket fuel varies depending on the type of fuel used. LOX, or liquid oxygen, is one of the cheapest options, costing around $0.27 per kg. LOX is the preferred oxidizer for large space launchers due to its safety, stability, and low cost. It has no characteristic odor and is transparent, with a light blue color. While LOX is cryogenic, it is not suitable for military applications that require quick launches.
The price of LOX is significantly lower than other rocket fuels such as LH2, which costs around $6.1 per kilogram, and RP-1, which costs $2.3 per kilogram. Solids are also more expensive, costing around $5 per kilogram as of 2008. Hybrid propellants can be even more costly, with HTPB priced at $8 per kg and hydrogen peroxide at $10.36 per kg. The most expensive fuel mentioned is hydrazine, which can cost up to $75.8 per kilogram.
The overall cost of propellant for a rocket launch can vary depending on the type of rocket and the amount of fuel required. For example, the Shuttle used a combination of liquids and solids, with a total propellant cost of approximately $4.6 million in 2008 prices. In comparison, the average launch cost was $450 million, highlighting that fuel costs are a small fraction of the total expenses.
The cost of LOX is also relevant for industrial applications, where high-volume oxygen users may consider installing a permanent, on-site LOX tank. This option comes with additional costs, such as a price per 100 CF, delivery fees, and equipment expenses, which can add up to significant amounts. However, it can also lead to substantial savings in the long run, as indicated in a sample calculation for a 120 SLPM HVO system.
While the exact prices may vary, it is clear that LOX is a cost-effective option for rocket fuel, with its low price per kilogram contributing to its popularity in the space industry.
