Meaning and Definition
The chemical process of producing methane (CH₄) from a mixture of carbon monoxide, carbon dioxide, and hydrogen.
A catalytic industrial process, crucial in energy technology and synthetic fuel production, where syngas is converted into methane, often as a step in creating substitute natural gas or managing carbon dioxide emissions.

FAQ
Frequently Asked Questions
The Sabatier reaction is a specific, well-known type of methanation (CO₂ + 4H₂ → CH₄ + 2H₂O). 'Methanation' is the broader term for any process producing methane from carbon oxides and hydrogen.
It's a key technology for energy storage (converting excess renewable electricity into storable methane) and for carbon capture and utilisation (CCU), turning CO₂ into a useful product.
Yes, in anaerobic environments like landfills or the digestive systems of ruminants, microorganisms produce methane via biological pathways (methanogenesis). Industrial methanation typically refers to accelerated catalytic chemical processes.
Managing the highly exothermic (heat-releasing) reaction to prevent catalyst damage and maintain high methane selectivity, especially when using CO₂ as a feedstock, which requires more energy than CO methanation.
The chemical process of producing methane (CH₄) from a mixture of carbon monoxide, carbon dioxide, and hydrogen.
Methanation is usually technical / scientific / industrial in register.
Methanation: in British English it is pronounced /ˌmeθəˈneɪʃ(ə)n/, and in American English it is pronounced /ˌmɛθəˈneɪʃən/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: METHANE + ACTION = Methanation. It's the action/process of making methane.
Conceptual Metaphor
CLEANING/CONVERSION: Often framed as 'cleaning' syngas by converting poisonous carbon monoxide into usable methane, or 'converting' waste CO₂ into a fuel.
