Enviroguard Gas Holder Balloons are flexible gas storage and containment systems used for the storage and handling of industrial and process gases. Manufactured using a high-tenacity polyamide fabric matrix with application-specific gas-resistant coatings. Flexible gas storage systems can be customized to suit different gases, capacities, operating conditions and installation requirements.
The biogas storage balloon construction combines mechanical strength, dimensional stability and resistance to demanding environmental conditions, making it suitable for industrial, energy, biogas and gas-handling applications.
A gas holder balloon is a flexible gas storage vessel used to temporarily store, collect or buffer gases generated or used in industrial processes.
Unlike rigid gas storage tanks, flexible gas holders are lightweight, transportable, and manufactured in capacities from 1 m³ to 200 m³. They are particularly useful where flexible, customized or temporary gas storage is required. For liquid storage applications, see our range of flexible liquid storage tanks.
Enviroguard Gas Holder Balloons can be engineered with gas-specific inner coatings and protective outer coatings depending on the gas composition and operating environment.
The gas holder balloon is manufactured using a high-tenacity polyamide fabric reinforcement for mechanical strength and dimensional stability.
The inner surface can be coated with Nitrile Rubber (NBR) or another application-specific polymer selected according to gas composition and service requirements.
CSM / Hypalon-type elastomeric coating options can provide resistance to weathering, abrasion, ozone, UV exposure and outdoor environmental conditions.
PVC-based construction can also be provided where gas composition and operating conditions permit its use.
Not every gas works with every material. The table below shows compatibility with NBR and PVC construction — confirm your specific gas composition with Enviroguard before final selection.

Every gas storage application has different requirements. Enviroguard can customize Gas Holder Balloons according to the gas being stored, required capacity, operating conditions, environmental exposure and installation requirements.
Enviroguard biogas storage balloons are designed for applications where flexible storage and buffering of biogas is required.
Material construction is selected based on biogas composition, concentration, moisture, temperature and operating pressure.
For biogas applications, share your gas analysis with the Enviroguard team and we'll confirm the right material construction.
The required gas holder capacity depends on your gas generation rate, consumption pattern, and how much buffer storage you need between generation and use. We offer standard models from 1 m³ to 200 m³. Custom sizes and configurations are available for larger or application-specific requirements.
For projects requiring capacities, dimensions or configurations outside the standard range, customized gas holder balloons can be engineered to meet the application requirements.

Contact for a Customized Gas Storage SolutionSize your gas holder to your biogas generation rate and consumption pattern. If your digester produces 50 m³ per day and your genset consumes gas continuously, a 10–20 m³ balloon provides enough buffer. If consumption is intermittent, you'll need a larger buffer — typically 30–50% of daily production. Enviroguard stocks models from 1 m³ to 200 m³ with custom sizes available.
Depending on material construction and operating conditions, Gas Storage Balloons can be designed for gases including biogas, syngas, hydrogen, carbon dioxide, nitrogen, oxygen, methane, carbon monoxide and other application-specific gases. Material compatibility should be technically evaluated before final selection.
Yes. Gas holder balloons are used to collect and buffer biogas from anaerobic digesters in wastewater treatment plants. The balloon stores gas between generation cycles and feeds it to flaring systems or gensets on demand. Enviroguard can customise the inner coating based on the specific biogas composition from your digester.
Yes, Enviroguard Gas Holder Balloons are listed for biogas production and storage applications. The final material selection should be confirmed based on the actual biogas composition, moisture, temperature, pressure and exposure conditions.
The construction uses high-tenacity polyamide fabric reinforcement with an application-specific inner coating such as NBR and an optional CSM / Hypalon-type outer coating. PVC-based construction may also be available where suitable.
The CSM/Hypalon-type outer coating provides resistance to weathering, abrasion, ozone, and UV exposure. This makes the construction suitable for demanding indoor and outdoor environments, subject to application-specific evaluation.
The compatibility information provided is intended as preliminary engineering guidance. Actual compatibility may vary depending on gas composition, concentration, purity, moisture, temperature, pressure, exposure duration, polymer formulation and construction.
Final material selection and suitability should be confirmed through technical evaluation and application-specific testing before use in critical or specialized applications.
