Biogas to the grid

Technical Data

Start of operation: September 2005

Capacity: 600 kW el. two-step plant with a retention time of approximately 160 days (digester + post-digester) 

Input: Corn silage, grass silage 

Thermal heat utilization: Company owned residentual buildings, gas refinement plant of 600 Nm³/h.

It all started with a planned expansion of their joint dairy operation. The two farmers from Godenstedt near Zeven came up with a different idea: a joint operation of a biogas plant.

They quit dairy farming – completely focused on the new project. They planned and implemented a plant solely run on energy crops, without the addition of liquid manure or other liquids. Gas necessary to run the CHP is produced by fermenting corn silage and grass silage.

In September 2007, the first MT-Energie large-scale plant for biogas-upgrading was put into operation in Godenstedt. This plant works with pressure-less amine gas treating technology, which allows an extremely economical and environmentally-friendly cleaning of raw biogas. With extremely low methane slippage, the methane content of the upgraded gas is around 99%.
