Methanation

Basics

• Methanation is the conversion of carbon monoxide and/or carbon dioxide to Methane through Hydrogenation
• Can be used to turn Hydrogen into Methane for fuel applications
  • This has the advantage of no risk of Hydrogen Embrittlement, and more "Conventional Support" (ie there are many OTS vehicles, generators, and tanks designed for CNG usage)

Methods

Biological

• Microbial Methanation wherein organisms are "Fed" hydrogen to produce methane
• The microrganism act as the catalyst, and allow for ambient reactor conditions, unlike the Sabatier Reaction
• Also given Anerobic Digestion produces CO2 as a waste product, they support eachother well
• Need to look up organisms used, bioreactor design etc

Chemical

• Sabatier Reaction
