Low-emission gases (including biomethane, but also low-emission hydrogen and e-methane) can play a crucial role in decarbonizing the natural gas and energy sectors in general. Biogas<\/strong> is produced from the decomposition of organic materials in the absence of oxygen by bacteria in special installations. Through decomposition, a mixture of gases is released: 45 - 85 vol% methane (CH\u2084), 25 - 50 vol% carbon dioxide (CO\u2082), hydrogen sulphide H\u2082S, etc. The feedstocks used to produce biogas include agricultural waste, food waste, manure, sewage, municipal waste. Biomethane<\/strong> is a purer form of biogas, consisting of about 100% methane, with a quality roughly equal to that of natural gas. Its multiple applications include heat and power for buildings and industry, but also the production of renewable fuels for the transportation sector.<\/p>\n

BIOMETHANE IS PRODUCED FROM BIOGAS,<\/strong><\/p>\n

Biogas is purified by removing CO\u2082 and other compounds, leaving only the biomethane. But there are other methods to produce biomethane: gasification of biomass, electrolysis and methanation, etc. These processes result in methane with a low or zero CO\u2082 footprint. EU annual production<\/a> now stands at 3 bcm (billion cubic meters), but experts estimate that 95 bcm will be needed by 2050.<\/p>\n

But what happens to the carbon dioxide obtained in the process of purifying biogas and converting it into biomethane? This carbon dioxide can be valorized in the food industry or used in greenhouses to enhance photosynthesis.<\/p>\n

...AND FROM BIOMETHANE, BIOGNL IS PRODUCED.<\/strong><\/p>\n

Biogas can be used to power combined heat and power (CHP) engines to produce electricity without having to be converted into biomethane. Excess biomethane production can be fed into the gas grid to replace fossil natural gas.<\/p>\n

Biomethane can be transformed into bio LNG (bio liquefied natural gas): the biomethane is liquefied and delivered to end-users, replacing fossil liquefied natural gas.<\/p>\n

WHY USE LNG AS FUEL?<\/strong><\/p>\n

This renewable substitute for LNG offers the same advantages that LNG offers over diesel:<\/p>\n
