Biogas supplyPhoto gallery
Pioneering in renewable energies through innovative and future oriented marketing is a continuous endeavour within EWE. Besides wind and solar, biomass plays a central role in shaping the future energy supply regime. On 8th November 2007, EWE inaugurated, in Werlte, a city in the Lower Saxony (Rural district of Emsland), the first biogas upgrading plant in Northern Germany. The plant brings biogas to the quality of natural gas before feeding it to the local gas network. The plant is coupled to the biogas power plant which was in operation since 2002, but which EWE took over in 2006. Thus the incoming biogas is upgraded in the plant attaining the quality of natural gas and the gas is directly fed to the gas grid. Therefore, biogas can now be used on a wider scale.

Important data about the purification plant
|
Manufacturer: |
Carbo Tech Engineering (Essen) |
|
|
| Principle: | Alternating Pressure Adsorption | ||
| Flow rate: | 500m3/h input biogas | ||
| Feeding: | Up to 3.6 MW HS (HS = 9.9 kWh/m3) | ||
| Problem: | Not always possible to feed into the distribution net work (At P=0.8 bar, the gas must alternatively be used in a CHP unit) |
