According to this agreement, the modular plants, with an output of 10 times 500 KW will be constructed from the middle of 2008 in Energiepark Linthe near Potsdam (southwest of Berlin). Biostrom Energy Group AG is currently constructing 17 plants with total output of 8.5 MW. The gas produced in the ten biogas plants in Linthe will be of natural gas quality and will be fed into the national gas grid.
Biogas is a mixture of gases which result from the anaerobic microbial decomposition of organic substances, of which 50-70% is methane – a top-quality energy source. Additional components are carbon dioxide (CO2) as well as traces of hydrogen sulfide (H2S), Nitrogen (N2), Hydrogen (H2) and carbon monoxide (CO). By upgrading and cleaning these components out of biogas, biomethane of natural gas quality can be obtained. When this renewable and carbon-neutral gas is fed into the main pipelines, it can be used for a range of end-uses, from home use to powering CNG-cars. Germany recently started looking into opening up the country's entire gas grid to accomodate biogas (more here and here).
Biostrom will supply the biogas plants with substrates obtained from dedicated energy crops. For this purpose, the company has taken out long-term leases on agricultural land. The 20-year leases will safeguard the supply of maize silage for the ten 500 kW biogas plants. Supplies for the CarboCompact plants - which include wood chips - will come from third parties:
ethanol :: biodiesel :: biobutanol :: biomass :: bioenergy :: biofuels :: energy :: sustainability :: Africa ::
BKN BioKraftstoff Nord AG has specialized in project development for biogas plants and the production of biodiesel. Thanks to Biostrom Energy Group AG and its operating subsidiaries, which BKN successfully acquired in April, BKN now operates successfully on the market for biogas plants as a prime contractor, covering the entire value chain: from maintaining competitiveness standards for plant locations to project planning, permit acquisition, construction and operation of biogas plants as well as the efficient control of the plants.
Biological process control for biogas plants, supported by Biostrom’s know-how, is one of its particular assets. BKN's subsidiary BioDiesel Bokel GmbH, which stemmed from an agricultural distillery cooperative, currently has a capacity to produce around 50,000 t/year of biodiesel. The company has already substantially increased its revenues and earnings over the past few years.
