1.1 What is biogas?
Nowadays hydrocarbons are one of the biggest energy bases of our society, but it is not renewable energy, and once they are exhausted they cannot be replenished. (but as it is not a renewable energy once they are exhausted they cannot be replenished) Therefore, scientists from around the world have researched the use of other energy resources to continue moving the world, such as solar and nuclear energy, which are two main areas of research. However, there are other energies, less known and therefore less used, like biogas.
Biogas is a renewable (source of) energy that belongs to the category of biofuels. It typically refers to a gas produced by the biological breakdown of organic matter in the absence …show more content…
It typically refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. The fermentation of biodegradable materials such as biomass, manure, sewage, municipal waste, green waste, plant material and crops produces biogas. The whole process works like a big concrete stomach would: Organic materials like manure, food scraps, crop residue, or wastewater sludge (known as feedstock) are fed into the digester, where it’s heated to 38-40 degrees Celsius (temperature of a cow’s stomach) and stirred for 30-60 days, slowly producing a combination of methane, carbon dioxide and other gases (known as biogas).
There are two key processes: mesophilic and thermophilic digestion which is dependent on temperature.
A mesophile is an organism that grows best in moderate temperature, neither too hot nor too cold, typically between 20 and 45 °C (68 and 113 °F).[1] The term is mainly applied to microorganisms. Organisms that prefer extreme environments are known as extremophiles.
Generally anaerobic digestion in the thermophilic range provides a number of advantages in relation held in mesophilic …show more content…
Injections includes? biogas until the breakthrough of micro combined heat and power two-thirds of all the energy produced by biogas power plants was lost, using the grid to transport the gas to customers, the electricity and the heat can be used for on-site generation resulting in a reduction of losses in the transportation of energy. La frase es largisima y no se entiende muy bien, poner puntos para hacerlo mas entendible.
1.4.3 Biogas in transport
If concentrated and compressed, it can be used in vehicle transportation. Compressed biogas is used increasingly more in Sweden, Switzerland, and Germany. For example, a biogas-powered train, named Biogaståget Amanda, has been in service in Sweden since 2005.
1.4.4 Measuring in biogasenvironments biogas environments
Biogas is part of the wet gas and condensing gas category that includes fog in the gas stream. The fog is predominately water vapour that condenses on the sides of pipes or stacks along the gas flow. Biogas environments include wastewater digesters, landfills, and animal feeding operations.
