Biogas plant tailor-made by Krieg & Fischer Ingenieure GmbH

Krieg & Fischer operate independently of subcontractors and can develop and implement the best technical and economical solution for your application. We place emphasis on the fact that there is no specific K&F procedure. Here we primarily focus on the input material and the conditions on site. This is the only way to develop an optimized system for your biogas plant.


Krieg & Fischer Ingenieure GmbH: Methanation - Bio SNG from biogas plants

„Currently, our renewable electricity production is limited during periods of low demand. Instead of shutting off wind and solar plants, we can convert this excess energy into gases that can be stored and used flexibly. By this, we can increase the share of renewable energies in our overall energy supply.” Tobias Eckhof, Project manager ‚Hydrogen‘ at Krieg & Fischer Ingenieure, evaluates this key technology.
Synthetic natural gas (SNG) is methane produced from biogenic carbon dioxide and hydrogen. This green and emission-free alternative is produced using the power-to-gas process. It is of natural gas quality and can be used like natural gas or fed into the gas grid. By linking the energy sectors of electricity, heat, mobility and industry (energy sector coupling), synergies are efficiently exploited.
This sustainable technology strengthens the economy and contributes to the achievement of climate targets.
From technology consulting and concept development, studies and approval procedures to plant planning and commissioning; Krieg & Fischer Ingenieure GmbH supports both the realization of new power-to-gas plants and the expansion of existing plants with its know-how.

Biogas plant DINTELOORD/ Netherlands

The owner and operator of the biogas plant is SUIKER UNIE GREEN ENERGY. In the biogas plant with an annual biogas production of 18.4 million m³ per year, residues from the sugar industry and vegetable waste are used. In the gas treatment by means of pressure water washing (DWW), the resulting biogas is treated to natural gas quality. This makes the biogas plant the largest biomethane producer in the Netherlands.

Bioethanol: An interview with Biogas Channel

Why can the integration of biogas and bioethanol production help to achieve the climate goals? Rio Cuarto biogas plant in Argentina is a successful proven of these synergies. Here more about this solution.

Krieg & Fischer Ingenieure GmbH: Successful for 10 years in the fermentation of sugar beets

An interview with Andreas Krieg on the advantages of fermenting sugar beet waste (sugar beet pulp) year-round in biogas plants as a solution for energy generation and CO2 compensation for the sugar industry. Surplus CNG is fed into the natural gas network, while fermentation residues are used as fertilizer.

"Krieg & Fischer Ingenieure GmbH is a planning office with more than 30 years of experience in the design and construction of biogas plants. We offer our services worldwide and are pleased to be able to talk directly to our international customers here at IFAT."

Biogasanlage  BELGOROD/ Russia

Energy from waste - a biogas plant for Russia. Built in 2011 by Krieg & Fischer Ingenieure GmbH and the video was broadcast on "Deutschland Welle" on 10.04.2013. The BELGOROD waste fermentation plant was commissioned in 2012 and uses, among other things, slaughterhouse waste, corn silage and sewage sludge.

First agricultural biogas plant with energy crops in Argentina

The first biogas plant in Argentina using energy crops is in operation since 2014. Already in 2017/2018 the biogas plant was extended. An additional digester and a second gas engine were added. The reason was that on top of the energy crops and manure, thin stillage and material from ethanol production are used as input substrate.
