Energy For The Future
Biogas
 versatile source of renewable energy: providing electricity and heat
 reduction of harmful methane emissions
 CO2 neutrality
 environmentally friendly way of preserving resources
Biogas Flow Diagram
Planning and Project Development
Project
 Conception
 Quotation
 Financing Assistance
 Approval planning
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
