ES #152: SpaceX Gas Demand

Energy Shots #152

This Friday, Elon Musk’s Space Exploration Technologies Corporation (SpaceX) is expected to see the largest IPO in history, with a planned Nasdaq listing under the ticker SPCX at an expected valuation of ~$1.75 trillion.

Backing up that record offering are SpaceX’s bold ambitions for an integrated platform across space, connectivity (Starlink), and artificial intelligence (xAI).

Dissecting these ambitions further, however, reveals the “muscle” of the system—a reusable launch vehicle standing 407 feet tall and nearly 30 feet wide, with a designed payload capacity of over 100 metric tons:

Starship.

And in an energy market characterized by myopic focus on data centers, a dedicated fundamental analysis of SpaceX’s latest workhorse highlights why the space industry represents a severely under-appreciated source of natural gas demand growth.

Quantifying Starship-Driven Demand Growth

According to SpaceX’s Starship V3 specifications:

• Super Heavy Booster: First stage of the Starship launch system powered by 33 Raptor engines, with total propellant capacity of 3,650 metric tons

• Starship (Spacecraft): Upper stage spacecraft of Starship system powered by 3 Raptor engines and 3 Raptor Vacuum engines, with total propellant capacity of 1,600 metric tons

• Propellant Mixture: Sub-cooled liquid methane and liquid oxygen in an approximate 3.6:1 oxygen-to-methane ratio for a total Starship propellant capacity of ~1,140 metric tons methane and ~4,110 metric tons liquid oxygen.

Adjusting for liquefaction, each Starship launch consumes ~55 million standard cubic feet of natural gas.

While relatively nominal in isolation, the magnitude of Starship-driven gas demand growth becomes more consequential in the context of medium-term launch frequency expectations stated by Musk or SpaceX President/COO, Gwynne Shotwell.

Using figures like Musk’s “>1000 Earth orbit flights per year by 2028” or the 10,000 per year by 2031 touted by both executives, Starship’s natural gas demand from launches alone expands to ~0.2 Bcf/d and ~1.5 Bcf/d, respectively.

In other words, Starship’s ~five-year launch cadence increases U.S. natural gas demand by roughly the same amount as a mid-sized LNG facility.

Long-Term Potential

While medium-term plans to scale Starship to ~10,000 launches per year are notable, SpaceX’s long-term ambitions for extraterrestrial data centers warrant a closer look.

Extending Musk’s math for the 100 GW and 1 TW per year scenarios to the requisite Starship launch cadence results in natural gas demand of ~0.8 Bcf/d and ~7.6 Bcf/d, respectively.

And when we look further into the future at SpaceX’s long-term target of launching each Starship three times per day across a fleet of 1,000 Starships, the program’s natural gas consumption balloons to over 150 Bcf/d—nearly 65% more than the average daily gas demand of the entire United States in 2025 or ~37% more than total Lower 48 dry gas production last month.
