Renewable Gases, Biogas, Biomethane: What Are We Talking About?
Renewable gases represent one of the relevant solutions to accelerate the transition towards a carbon-neutral world. That's why ENGIE is committed to expanding their production.
But what exactly are renewable gases? Biomethane, synthetic methane, renewable hydrogen, and e-fuels. These gases are produced from various types of waste or renewable electricity.
Renewable gas can be produced in three ways. Biomethane is produced after the purification of biogas derived from the anaerobic digestion of organic waste. Through pyrogasification of solid waste or hydrogasification of liquid waste, we obtain what is known as synthetic gas. Renewable hydrogen, on the other hand, is primarily produced through water electrolysis using renewable electricity and, through a process of methanation, can also yield synthetic methane.
