First major carbon neutral brewery
The brewery has different energy sources: biogas generated by the spent grain fermentation and the anaerobic waste water treatment plant which is used directly for steam production and to produce heat and electricity in a CHP facility. In a nearby sawmill wood is burned in a CHP ORC plant and the heat as warm water is used in the brewery, solar thermal energy providing for up to 5% of the brewery’s energy demand. A storage of 200 m3 is also included to store hot water from the solar thermal plant. The whole energy usage was optimized by a excess heat recovery concept.
Collector area: 1520 m2
Collector type: flat plate
Other energy sources: biogas, district heating, excess heat
Storage: 200 m3 short term water storage
Installation year: 2013
