What 35.21Y includes

• Production of gaseous fuels to provide energy through a gas distribution network (for example, by distillation of coal, gasification of lignite, electrolysis or anaerobic digestion)
• The production of gaseous fuels to provide energy to a calorific value determined, by purification, blending, or other treatment of gases of various origins, including the natural gas or hydrogen
• Production of biogas for the needs of the gas supply (e.g. from sewage sludge, manure, waste)
• The production of biofuels, gas for the supply of energy through a gas distribution network
• Cleaning of the biogas for energy provision via a permanent network
• The regasification of natural gas for distribution via pipelines
