Reliable Biogas Storage for Continuous Energy Supply
A biodigester does not always produce gas at the exact moment it is required. A flexible gas storage balloon creates a buffer between production and use, allowing biogas to be collected, stored and released according to demand.
Dominion Biogas Services sizes each storage balloon according to daily gas production, peak consumption, desired reserve period, operating pressure and available installation space. The storage system can be integrated with gas purification, pressure regulation, condensate control and distribution equipment.
Store Energy When Produced. Use It When Needed.
Stores gas during low-use periods for later consumption.
Reduces interruptions when demand rises temporarily.
Helps create smoother low-pressure gas delivery.
Reduces unnecessary gas accumulation within the digestion system.
Makes stored gas available during heavy cooking or operating periods.
Additional storage can be added as gas production increases.
Suitable for Multiple Biogas Projects
Typical Storage Capacities
Final storage capacity is calculated from actual gas-production and consumption data. The following ranges are general planning guides.
| Storage Volume | Typical Application |
|---|---|
| 1–3 m³ | Small household cooking systems |
| 4–10 m³ | Large homes, apartments and small restaurants |
| 10–30 m³ | Hotels, schools, hospitals and farms |
| 30 m³ and above | Commercial and institutional projects |

Daily production, peak demand and use patterns are reviewed.
Capacity Selection
The storage volume is sized to the required buffering period.
Site Preparation
A clean, protected and ventilated location is prepared.
System Integration
The balloon is connected to purification, regulation and distribution equipment.
Leak Testing
Connections, valves and storage membrane are checked.
Handover
Operating, inspection and maintenance procedures are explained.
Build a Complete Gas Management System
Storage Sized for the Whole Biogas System
A storage balloon should not be selected from digester size alone. Correct sizing considers actual gas yield, daily consumption, peak demand, pressure, purification and the desired reserve period.
Dominion Biogas Services integrates the storage balloon with the digester, purification system, pressure regulator and end-use network to create a complete and reliable gas-management solution.
✓ Professional Sizing
Capacity is based on production and demand.
✓ Complete Integration
Storage is coordinated with purification and regulation.
✓ Safe Installation
Location, ventilation and protection are considered carefully.
✓ Testing and Training
The system is inspected and users receive guidance.
✓ Long-Term Support
Maintenance and system-expansion services are available.
Important Safety Notice
Biogas is flammable and may contain toxic hydrogen sulphide. Storage balloons must be installed in protected, ventilated locations away from flames, sparks, excessive heat and sharp objects. The gas system should include suitable valves, pressure control and leak testing, and installation should be carried out by qualified personnel.
Questions Clients Frequently Ask
Why do I need a gas storage balloon?
It stores gas produced when demand is low and makes it available when demand increases, improving the reliability of the overall system.
How is the correct capacity determined?
Capacity is based on daily gas production, consumption pattern, peak demand and the number of hours or days of reserve required.
Can it be installed outdoors?
Yes, but it should be placed inside a suitable protective enclosure and protected from weather, sharp objects, flames and unauthorised access.
Does the balloon create gas pressure?
Flexible balloons store gas at low pressure. Additional regulation or controlled weighting may be used where more stable delivery pressure is required.
Should gas be purified before storage?
Moisture and hydrogen-sulphide reduction are generally recommended to protect the balloon, piping and downstream equipment.
Can several balloons be connected together?
Yes. Multiple balloons can be arranged as a modular storage system when larger capacity or operational flexibility is required.
How long does a storage balloon last?
Service life depends on membrane quality, gas quality, installation conditions, protection from sunlight and damage, and maintenance.
Why is there no fixed price?
Price depends on storage volume, membrane specification, enclosure, valves, pressure-control equipment, piping and installation requirements.
