NASA Challenge - CO2 Conversion

Click For Summary
SUMMARY

NASA is initiating a challenge to develop a process for converting CO2 into carbon sources on Mars, with a prize of $50,000. The challenge is open to U.S. citizens, permanent residents, and U.S. business entities, requiring all work to be conducted in the U.S. Key processes discussed include Fischer-Tropsch synthesis for producing hydrocarbons and the potential use of electrolysis, electrical discharge, or radiolysis for CO2 decomposition. The challenge emphasizes the need for purification of CO2 from Martian dust and gases, while allowing the use of additional reagents and catalysts.

PREREQUISITES
  • Understanding of Fischer-Tropsch synthesis and its applications in hydrocarbon production.
  • Knowledge of electrolysis and its role in chemical decomposition processes.
  • Familiarity with the Sabatier process and its relevance to CO2 conversion on Mars.
  • Basic principles of chemical engineering and catalysis.
NEXT STEPS
  • Research the Fischer-Tropsch synthesis process and its industrial applications.
  • Explore advanced electrolysis techniques for CO2 decomposition.
  • Investigate the Sabatier process and its limitations in extraterrestrial environments.
  • Study methods for purifying CO2 from Martian dust and other contaminants.
USEFUL FOR

This discussion is beneficial for chemical engineers, researchers in extraterrestrial resource utilization, and innovators focused on sustainable fuel production from CO2.

NASA is looking for a process to use CO2 as a Carbon source on Mars; ultimate goal is to use the Carbon in the synthesis of other products.

$50,000 prize.

Open to U.S. citizens, permanent residents, and U.S. business entities, work must be done in the U.S.,

Looks like Navy might have a head start. They can make jet fuel out of the CO2in seawater.

I'm not enough of a chemist to assess difference between hydrocarbons and carbohydrates though.

Seems right out of Science Fiction's Golden Age, doesn't it ?

Look into Fischer-Tropsch synthesis.

"Liquid transportation hydrocarbon fuels and various other chemical products can be produced from syngas via the well-known and established catalytic chemical process called Fischer-Tropsch (FT) synthesis, named after the original German inventors, Franz Fischer and Hans Tropsch in the 1920s," and it was industrialized in the 1930s.

CO2 can be decomposed in a hydrogen environment with electrolysis, or electrical discharge, or radiolysis. One can produce methylene, and even carbon black. That's been known for decades.
 
So the Sabatier process, researched for Mars Direct project, is no longer a valid option?

Apparently, they like sugars as outcome.
 
I would expect that the synthesis steps (=this challenge*) are the easier parts - you can use well-established processes from Earth. Cleaning the CO2 from dust and the other gases is a challenge unique to Mars.

* according to the rules you can use a source of pure CO2.
Other consumable reagents/catalysts are of course allowed as part of the conversion process (e.g., acids/bases/metals).
That is interesting (highlight from me).
