Currently, biomethane plants emit approximately one-third of the carbon in biogas into the atmosphere in the form of carbon dioxide. Since this CO2 is of biogenic origin, it does not pose a problem in environmental inventories, as it would have been emitt anyway in the natural decomposition of organic matter. However, the use of CO2 as a renewable source of carbon could be relevant in the future . Many industrial processes, such as methanol production, are beginning to replace fossil carbon with biogenic carbon. Upgrading plants could offer their high-quality carbon dioxide, superior to that obtain from other sources such as capture in biomass combustion processes or directly from the air. In this sense, the valorization of this byproduct could improve the economic viability of upgrading plants .
Measures are underway
Another technological alternative to the separation and subsequent conversion of CO2 into products of interest is the production of biomethane by combining it with hydrogen , known as the Sabatier reaction. This process converts CO2, which how to write article titles to effectively attract customers, increase click-through rate and search rankings when doing foreign trade seo is normally reject at upgrading plants , into more biomethane. Since it is the same product that is already being generat, efforts are unifi in the injection, distribution, and marketing stages. However, the key advantage of this option is that the previous stage of CO2 separation can in fact be avoid, eliminating the ne for upgrading, since methane does not negatively interfere with the Sabatier reaction process, making it an efficient alternative for increasing biomethane production.
Renewable energies essential to combat climate change
The temporary combination of hydrogen and biogas addresses some of hydrogen’s main limitations, such as the ne to store it at high quickly create beautiful emails pressures or in cryogenic conditions, and ruces investment in new specializ infrastructure.
An additional benefit of this process is that it opens the door to hydrogen production in rural areas , where land is more available for installation and where renewable energy sources such as wind and photovoltaic can supply them with green electricity. Furthermore, the temporary combination of hydrogen with biogas overcomes agb directory some of hydrogen’s main limitations, such as the ne to store it at high pressures or in cryogenic conditions, and ruces investment in new specializ infrastructure. This combination, although temporary, represents a strategic synergy for both renewable gases.
