What Could Go Wrong? Elon Musk Announces Plan to Take CO2 out of Atmosphere and Convert It Into Rocket Fuel

MSN:

Elon Musk announced on Monday that his company is working on a program to take carbon dioxide (CO2) out of the atmosphere and convert it into rocket fuel, claiming that it will be important for his future missions to Mars.

Musk announced the news on Twitter and invited people to participate in the program, writing: “SpaceX is starting a program to take CO2 out of atmosphere & turn it into rocket fuel. Please join if interested.”

“Will also be important for Mars,” he added.

The Tesla chief executive did not elaborate further on the new sustainable fuel program but as per the company’s website, the SpaceX Falcon 9 rocket uses rocket-grade kerosene (RP-1) propellant as fuel.

According to Tesla, Falcon 9 is the world’s first orbital-class reusable two-stage rocket designed to safely transport people and payloads into Earth orbit and beyond. Tesla says its reusability allows SpaceX to re-fly the most expensive parts of the rocket, lowering the cost of entering space.

The kerosene used in the SpaceX Falcon 9 rocket emits carbon dioxide, carbon monoxide, carbon soot, and a small number of sulfur compounds, among other chemicals, into the atmosphere.

Carbon dioxide, mainly emitted from the combustion of fossil fuels such as coal, oil, and natural gas, is the largest contributor to greenhouse gases.

In 2019, CO2 accounted for roughly 80 percent of all U.S. greenhouse gas emissions from human activities, according to the United States Environmental Protection Agency.

According to Champion Traveler, the Falcon 9 burns 29,600 gallons (112,184 kilograms) of highly refined kerosene, while 3.0 kilograms of CO2 goes into the atmosphere per kilogram of kerosene burned, meaning that roughly 336,552 kilograms of CO2 is added into the atmosphere per Falcon 9 launch.
