Agricultural Biogas

A highly efficient and profitable alternative for power generation

XLS Energy offers durable and reliable solutions for the use of biogas. This gas, a by-product of many agricultural, food processing and industrial processes is used today as a fuel for power generators with gas engines.

Biogas from renewable energy sources and biogas plants

Energy from biomass can make a tremendous contribution towards sustainable power supply. Currently biogas offers the highest user benefits and the best use of the energy potential of biomass. Biogas is produced from the anaerobic fermentation of organic material in the fermenter of a biogas system. Biogas, consisting primarily of methane and carbon dioxide, is created during the anaerobic decomposition of organic waste materials. This gas has a methane CH4 content from 45 to 70 percent. During its combustion, it only releases as much CO2 as the plants absorbed during their growth. Cogeneration power plants that produce electricity from biogas prevent emissions that would otherwise be released by fossil fuels.

Instead of allowing uncontrolled decomposition of these wastes and the release of gases into the atmosphere, they are contained in an oxygen-deprived environment such as a covered lagoon or above ground steel tank. From there, methane is extracted and burned to generate electricity or heat.

Because of the impurities and inconsistencies in biogas, pretreatment is generally required. However, using a gas engine specifically designed to operate on biogas can reduce the amount of investment in pretreatment.

Our gas engines (generator sets) are engineered to handle fuel with variations in methane content typical of biogas operations.

XLS Energy’s technology includes gas engines that are specially designed for the combustion of biogas:

  • A crankcase ventilation pump to eject potentially acidic blow-by gases
  • Specially designed after-cooler cores, cylinder heads, main bearings and connecting rod bearings that are hardened against corrosive elements
  • Differentiated cooling systems to operate at elevated jacket water temperatures to prevent condensation of contaminants

XLS Energy offers gas engines specially matched to biogas, complete systems as well as containers for combined heat and power. These systems achieve the highest levels of efficiency in the various power segments. What’s more, XLS Energy also provides the required system components for gas treatment and purification. For installation of the generator in remote areas, the generated energy can also be used exclusively by the system.
