Biomass

Biomass: The perfect cycle

The idea is simple and sustainable at the same time: waste that has already been produced and needs to be disposed of is transformed into energy in a completely natural, biochemical process. And that in numerous forms, such as electricity, heat, bio-natural gas, or even alternative fuels. It’s definitely energy with a future.

How biomass becomes pure energy

Natural agricultural byproducts like manure, vegetable waste, and other organic waste form the energy basis for biogas production and are converted in a special fermentation process. EWE further refines the gases produced (e. g., methane) so that they can be used as bioenergy. The recycling cycle ends with the processed residues going back to the soil as a high-quality fertilizer for agriculture. It’s sustainable and makes sense.

Another big advantage: short distances. Biogas is mostly used in the immediate vicinity of the production sites, for example, in combined heat and power plants, which supply customers and businesses with power, who, in turn, are supplied through energy derived by biomass.

EWE operates eight plants for the processing and distribution of biogas. As early as 2002, we began with biomass energy generation in Werlte, Lower Saxony. It was one of the first plants in Germany to distribute biomethane into the natural gas grid. Here, processed biogas is used for electricity and heat generation in combined heat and power plants and can also be used to power natural gas vehicles. Biogas belongs to the renewable energy category because it’s climate-neutral and can even be stored in the natural gas network.

Your partner in biomass energy

Our EWE experts always ensure safe operations and a maximum of efficiency. This includes innovative energy systems such as Power to Gas or Power to Liquid systems from our external partners. They receive CO2 or methane from the EWE biogas plants for the production of synthetic fuels. The fermentation residues used in biogas production can be fused as high-quality fertilizer for agriculture. And that’s a cycle we can all get excited about!
