BIOGAS/BIOMETHANE COMPRESSION SOLUTIONS

For 75 years, BAUER has been a global leader in the development and manufacturing of compressor systems for a wide range of applications. 

Our systems are internationally recognized for extreme durability and reliability – a reputation we have earned through consistent quality and engineering excellence. 

What sets BAUER apart

• Lifetime support for all systems 
• Global presence: 35 locations in 20 countries, over 600 distribution partners worldwide 
• Unlike many manufacturers, BAUER delivers more than just compressors.We provide the complete compression solution from a single source – from engineering to final system integration. 
• While many providers rely on external system packagers, BAUER takes on the entire manufacturing process and responsibility for the complete system. 
• This means: highest quality, seamless processes, and maximum operational safety for our customers. 
• Industry expertise: Biogas & Biomethane 
• BAUER possesses extensive experience in the field of biogas and biomethane purification. 
• Over 500 successful plant installations in biogas upgrading 
• More than 2,000 CNG systems in operation worldwide 
• Our systems prove their value even in demanding applications through efficiency, longevity, and uncompromising quality – from single components to complete solutions. 

Methane (CH₄) is an extremely potent greenhouse gas with an atmospheric lifespan of about 12 years. 

Although it is shorter-lived than carbon dioxide (CO₂), it has more than 80 times the global warming potential over a 20-year period, as it traps heat in the atmosphere much more effectively. 

In Germany, over 75% of total methane emissions come from agriculture. The main sources are: 

• Enteric fermentation: Methane is produced in the digestive systems of ruminants such as cattle and sheep. This process contributes significantly to emissions. 
• Manure management: The storage and spreading of liquid and solid manure also causes substantial amounts of methane. 
• Other contributors include waste management, wastewater treatment, and the energy sector – particularly due to gas infrastructure leaks.  

Given methane’s high climate impact, the gas is increasingly becoming the focus of legal regulations. The European Union has introduced new directives, particularly obligating the energy sector to monitor and reduce emissions. 

Germany also faces the need for action – especially in agriculture.  The federal government has committed to significantly reducing methane emissions by 2030. To achieve this, comprehensive measures are necessary, including both technical solutions and structural changes in livestock farming and manure management. 

Complete solutions for the recovery and purification of biogas directly on site 

Producing biomethane from landfills, dairies, and wastewater treatment plants via anaerobic digestion not only reduces methane emissions into the atmosphere – it can also represent an attractive additional income stream for plant operators: 

• Feeding the purified gas into the grid and selling it to energy suppliers 
• Cost savings through using self-produced biomethane for fueling vehicle fleets 
• In-house electricity generation via combined heat and power (CHP) 

BAUER is globally recognized for its expertise in the manufacturing of gas compressor systems. To offer our customers complete turnkey solutions for biomethane upgrading, BAUER works with selected partners who specialize in specific technologies and processes in biogas production. 

• Biogas feed compression 
• Compression for grid injection 
• Compression for virtual pipeline/CNG filling stations
