Biogas plant Ihausen
It was the right decision for us to get into the biogas production business. We produce renewable energy from late grassland cuts, which is biomass that’s sustainable and available without competition. Together with a highly efficient process we bear comparison to any other kind of renewables.
The biomass production from grassland is a sustainable concept since we consider both landscape and soil protection aspects. In the grassland regions we have a lot of biomass available which is not used for food production any more or which is a by-product of the grassland utilization in the second half of the year. Thus we create synergies with the likewise developing milk production.
We produce electricity for more than 1.000 households with only a fraction of the area around the villages!
We decided for to go with BioConstruct because they built the plant exactly the way we needed it for our concept.
Ihausen, June 4th2010
Yes, we have to ungrudgingly acknowledge that you can find the major know-how in the matter of grass fermentation not at BioConstruct but in Ihausen. We’re very impressed by the way Mr. Geveke was able to optimise the grass fermentation in his biogas plant and we’re very pleased to be able to always draw upon his vast wealth of experience. After all we’ve been the ones who designed the solid basement for his key to success. “Small fermenter, big mixers, short ways”, is how Mr. Geveke describes it in the Biogasjournal 02/2008. Since commissioning in the last quarter of 2005 things have changed a lot. Today the Gevekes can intermittently digest up to 100% of grass silage with a capacity utilisation of 92%!
The thermal energy supplied by the biogas plant is used to heat two homes, the in-house work shop and to dry more than 2.500 m³ of high quality firewood. During the summer of 2010 another 15 mor homes will be connected to the heat supply. To get more redundancy and always be able to run the plant with 100% of grass silage a fourth fermenter will be built. Mr. Geveke is further planning a cooperationn with a nearby dairy farm. A manure pipeline from the farm to the biogas plant and the installation of several satellite CHP units at different heat sinks are in planning. In 2007 the plant has already been expanded from 190 to 500 kWel.
It’s good to know that plants from BioConstruct are designed for all future options right from the start.
Are you now waiting to get all the tips and tricks to make grass fermentation successful? Well, we can’t reveal everything in the internet … But we would be pleased to also build your biogas plant. And then we’ll reveal everything we know!
