Reply by Baptiste Usquin, Waga Energy:

Biomethane is a renewable gas that substitutes fossil natural gas. When there are different to produce renewable electricity (solar, windmills), biomethane is replacing directly a fossil energy that is imported in Spain from foreign countries. On an environmental point of view, it makes much more sense producing biomethane than producing electricity out of biogas (it generates nearly 3 times more energy).
