Manufacture of gas; distribution of gaseous fuels through mains

Notes from sub-category 35.21.00:

• –manufacture of gases other than petroleum gases for the provision of gaseous fuels through a permanent supply network (for example, coal gas, water gas, producer gas, gasworks gas)
• –production of gaseous fuels for energy supply through a gas distribution network (e.g. by carbonation of coal, gasification of lignite, electrolysis or methanisation)
• –production of gaseous fuels for energy supply with a specified calorific value, by purification, blending and other processes from gases of various types, including natural gas or hydrogen
• –production of biogas for the purpose of gas supply (e.g. from sewage sludge, manure, waste)
• –production of gaseous biofuels for energy supply through a gas distribution network
• –cleansing of biogas for energy supply through a permanent network
• –regasification of natural gas for distribution through mains

Notes from sub-category 35.22.00:
