Biogas and Dimethyl ether are providing water, fertilizer for an intelligent smart soil Buchkatalog

Technischer Bericht aus dem Jahr 2018 im Fachbereich Energiewissenschaften, Note: 1, , Veranstaltung: Erneuerbare Treibstoffe, Sprache: Deutsch, Abstract: Biogas is well known in agriculture and food industry. In Austria we realized a project Hagenbrunn nearby Vienna/ Austria, a biogas plant running on waste food and liquid biogenic waste. The electric power output is given with 1320 kW ele, the thermal heat generation is given with 1800 kW thermal heat realized with warm water (95°C/60°C), the substrate feed is given with 25 000 t/year, and the digestate coming out of the biogas plant is 35 000 t/year. The biogas generation of the different substrates, like waste food, grass, potatoes (e.g.) is done by measurements, testing and calculation and leads to the biogas generated by fermentation in a range of 700 Nm³/h up to 800 Nm³/h, with a methane concentration of 50% up to 65%. The biogas plant Hagenbrunn has a deep influence on the way of irrigation, the way of fertilizing in agriculture and vine culture. The biogas plant Hagenbrunn has a deep influence on the regional jobs, the regional companies, it is acting like a knot and center of competence and initiating a lot of spin offs. The main advantage of the biogas plant is using biogenic waste as input substrate and therefor the communities are glad to have a sink using and converting waste food and liquid biogenic waste to biogas. Biogas from the plant is only an intermediate step. In the first realization step biogas is converted to electricity and heat.
