Double Membrane Biogas Holder

The Efficient, Low-Maintenance Gas Storage Solution for Industrial & Environmental Applications 

High-Performance Industrial Gas Storage

A cost-efficient, reliable solution for diverse gas storage needs

A double membrane biogas holder is a cost-efficient industrial gas storage system comprising a bottom membrane, an inner membrane, and an outer membrane. The inner membrane securely contains the gas, while the space between the outer and inner membranes forms a pressure regulation chamber. A constant-pressure control cabinet automatically manages this space by inflating or exhausting air, maintaining system pressure for safe, continuous, and stable gas supply.

This robust biogas storage system is ideal for neutral gases like biogas and air, offering significant storage capacity, excellent corrosion resistance, and straightforward maintenance.

Large Storage Capacity

The flexible membrane design provides substantial volume, effortlessly meeting the high gas storage demands of large-scale industrial operations. 

Quick & Easy Installation

Featuring highly modular components, our double membrane gas storage tank solutions allow for rapid on-site assembly with flexible foundation requirements, significantly shortening project timelines. 

Efficient & Reliable Operation

The integrated constant-pressure control cabinet automatically adjusts the inter-membrane pressure, ensuring stable gas input and consistent output for dependable system performance. 

Low Maintenance & Long Life

Constructed from materials with superior corrosion and aging resistance, the structure requires minimal inspection. Fully automated operation further reduces long-term operational and maintenance costs. 

Biogas & Renewable Energy

Used in landfills, wastewater treatment plants, and agricultural biogas projects to store anaerobic digestion gas (methane). 

Industrial Gas Handling & Recovery

Suitable for chemical, food & beverage, and steel industries to buffer or store process gases like CO₂, O₂, or N₂. 

Environmental & Carbon Management

Serves as a critical buffering or transfer unit in CCUS and waste gas treatment projects for temporary storage of captured CO₂.

Distributed Energy & Emergency Storage

Provides a flexible, reliable gas storage solution for biogas/natural gas-powered energy stations and industrial backup reserves.  

Uses an inner membrane for storage (automatically expanding/contracting) and an outer membrane for pressure balance and protection, ensuring stable pressure.

Includes a complete control system (sensors, valves, panels) and undergoes rigorous leak testing. Designed with a 1.5x safety factor over working pressure.

Features quick installation with prefabricated components and simple upkeep (leak checks, monitoring), leading to low operational costs. 

Operates in temperatures from -40°C to +70°C. Ideal for large biogas projects, landfills, food processing, wastewater treatment, and agriculture.
