Methane sourced.

Methane is a much worse greenhouse gas than CO2.

Blue overlaps with grey hydrogen which used both methane as the feedstock but differ in production.

Add to that they both still need the entire carbon rich transport sector to work so neither are really carbon neutral despite the attempts at carbon capture for blue.
