Biogas Storage Domes – Reliable Flexible Gas Holder Solutions
Biogas storage domes are a critical component of modern anaerobic digestion and renewable energy systems. They provide safe, efficient, and flexible storage of biogas generated from organic waste, agricultural residues, industrial by-products, and municipal wastewater. DERFLEX specializes in manufacturing high-performance PVC coated membrane materials used in flexible biogas storage domes, supporting stable operation and long-term performance for biogas plants worldwide.
Overview of Biogas Storage Domes
Biogas storage domes, also known as flexible gas holders or membrane gas domes, are designed to temporarily store biogas before utilization in combined heat and power (CHP) units, boilers, or upgrading systems. Compared with rigid steel tanks, membrane-based domes offer superior flexibility, reduced construction costs, and excellent adaptability to variable gas volumes.
DERFLEX biogas storage dome membranes are engineered to meet the demanding requirements of biogas environments, including continuous outdoor exposure, chemical resistance, and pressure fluctuation.
Why Flexible Biogas Storage Domes Are Essential
In biogas systems, gas production and consumption rarely occur at the same rate. Biogas storage domes act as a buffer, ensuring a stable gas supply and protecting downstream equipment. High-quality membrane domes are essential to prevent gas leakage, reduce odor emissions, and maintain system safety.
- Maintain stable biogas pressure
- Prevent methane leakage
- Improve energy utilization efficiency
- Enhance plant safety and environmental compliance
Types of Biogas Storage Domes
Single Membrane Biogas Domes
Single membrane domes are typically used for low-pressure biogas storage applications. They offer a cost-effective solution for agricultural digesters and small-scale biogas plants.
Double Membrane Biogas Storage Domes
Double membrane systems consist of an inner gas-tight membrane and an outer protective membrane. The space between membranes is pressurized by air, providing structural stability and enhanced safety.
- Higher gas storage capacity
- Improved safety and redundancy
- Better resistance to wind and snow loads
