More than 12 years of experience in designing, planning and
construction of biogas power plants.
Input of the first plants: organic waste (fats and flotates);
Weser-Ems region: intensive livestock farming
Biogas-boom since amendment of
the EEG (law on renewable energy)
in 2004
More than 250 biogas plants built
Installed capacity over 140 MWel

Plant Construction
Building phase
bwe installation teams set up the agitators, gas storage roofs
and pipelines
Use of low maintenance and energy-efficient agitators
Connection of the high performance CHP units with engines
upward of 190 kW
Technology
Biogas plant
User friendly process control systems
Control of individual plant components and documentation of the control
parameters
Remote access to the control system
Natural Gas From Biogas
Biogas Preparation
Often there are no possibilities to use the heat economically
Upgrading of biogas to natural gas quality
Transportation through the existing natural gas network
Alternative use as fuel for vehicles
Heat use
Transportation of heat
Increasing efficiency by utilizing surplus heat
Use of district heating for nearby houses and stables
Wide variety of possible consumers,
e.g. heat for drying plants (cereals or digestate)
Arbitrary choice of temperature level (default at 85 °C)
Micro-Gas Distribution System
Transportation of biogas
the CHP is placed next to the heat consumer
transport of biogas to the CHP unit through a gas pipeline
lower investment required compared to district heating
more efficient use of thermal energy, no losses during transportation
