The first human use of methane dates
The first human use of methane dates back to 3000 BC, when the Assyrians used it for washing.
Biogas is a renewable fuel that can be used for various purposes including electricity and heat generation and as a clean air friendly transportation fuel.
In the United States, biogas is mostly extracted from landfills where it is produced and from the anaerobic treatment of animal waste in livestock farms.
By 2020, about 90 percent of the biogas produced in the United States will come from landfills. However, in the United States, biomethane also comes from agricultural waste from large farms. In fact, livestock carbon emissions account for one-third of the US nation’s methane emissions.
Due to state and federal support, the United States is the global leader in the use of biomethane for transport.
Biomethane is an energy-rich gas that is created during the anaerobic decomposition of organic matter. It is composed primarily of methane and carbon dioxide. In its raw form, biogas may contain between forty and sixty percent methane and only small amounts of water vapour and other gases. After refining, biogas can be used to replace natural gas.
Although biogas and biomethane have similar properties, there are some differences between them. Biogas generally contains more hydrogen than biomethane, but is not generally considered compatible with natural gas due to other impurities.
Biogas has the same methane molecule as natural gas and can therefore be used in LNG engines. Because it is 99.9 percent methane, biogas is considered cleaner than LNG and is made from organic matter. Biogas also emits less greenhouse gases.
Biogas has many advantages as a raw material for biomethane production. But biomethane wins because experienced biomethane plant owners can help prevent outages anywhere.
Biogas occurs naturally in atmospherically controlled environments. In addition to reducing the use of fossil fuels, biomethane can also produce biofertilizers that provide organic carbon to the soil. That process also helps reduce the need for mineral fertilisers. These are all positive steps in a sustainable energy supply chain.
