The global push for decarbonization and the transition to a sustainable energy future has brought biomethane, also known as Renewable Natural Gas (RNG), to the forefront of the renewable energy sector. As a purified and upgraded form of biogas, biomethane is a high-value commodity that can be injected into the natural gas grid or used as a clean vehicle fuel. The successful integration of biomethane into the energy infrastructure, however, requires a reliable and highly efficient storage solution. This is where Double Membrane Gas Holder Roofs play a critical role, providing the ideal technology for safe and effective Biomethane Storage. These innovative systems are not just covers; they are intelligent, flexible components that ensure biomethane is contained, protected, and supplied consistently for downstream energy use.

A Double Membrane Gas Holder Roof is a sophisticated, all-in-one solution that revolutionizes gas containment, particularly for the unique demands of high-purity biomethane. Unlike traditional systems that may use a separate rigid cover and an external gas storage tank, this design combines these two critical functions into a single, cohesive unit installed directly on top of the storage tank. This integrated structure not only simplifies the project structure but also enhances overall performance and safety.
A typical Double Membrane Gas Holder Roofs system consists of a double-membrane structure made from specialized, high-strength, gas-tight membrane material, usually PVC-coated polyester fabric. This material is chosen for its exceptional gas impermeability, superior resistance to corrosive elements (even after purification), and remarkable durability against environmental factors:
Inner Membrane: This flexible membrane serves as the primary gas storage chamber. As biomethane is continuously produced and purified, the inner membrane dynamically inflates to accommodate the increasing volume. This adaptive capacity is crucial for managing the variable gas production rates from the upstream biogas upgrading process. The membrane gracefully deflates as biomethane is drawn off for utilization, ensuring a consistent and uninterrupted gas supply to downstream equipment like grid injection points or vehicle fueling stations.
Outer Membrane: This robust external layer forms a permanently inflated, dome-like shape. It is consistently maintained under a slight positive air pressure, supplied by a low-pressure air blower. The outer membrane acts as a vital protective shield, safeguarding the inner membrane and the stored biomethane from adverse weather conditions, including high winds, heavy precipitation, and damaging UV radiation. The controlled air pressure within the inter-membrane space also provides structural stability and ensures the inner membrane can move freely, maintaining the stable pressure needed for consistent biomethane delivery.
This dual-membrane design is fundamental for modern Biomethane Storage. It ensures absolute airtightness, preventing valuable biomethane leakage and protecting the gas purity from external contamination.
Our Double Membrane Gas Holder Roofs offer a range of significant advantages that make them a superior choice for modern Biomethane Storage:
Exceptional Gas-Tightness and Safety: The double-membrane structure and advanced welding techniques ensure an exceptionally gas-tight system, preventing methane emissions and protecting gas purity. The integrated pressure management features also safeguard the system from over-pressurization or vacuum damage, enhancing overall plant safety.
Cost-Effective and Efficient: By combining the functions of a tank cover and a gas holder, this solution reduces the need for separate gas storage tanks and complex piping, leading to lower material, construction, and installation costs, which is crucial for a competitive biomethane market.
Superior Durability and All-Weather Performance: Made from durable, corrosion-resistant, and UV-stabilized PVC-coated fabric, our roofs can withstand harsh weather and the inherent nature of gas storage. This ensures a long service life with minimal maintenance.
Enhanced Thermal Insulation: The insulating air gap helps maintain a stable temperature for the stored gas, preventing condensation and preserving the gas quality, which is vital for meeting the stringent standards of biomethane.
Low Maintenance Requirements: Unlike rigid covers that require frequent inspection and corrosion protection, our membrane roofs have minimal maintenance needs, reducing long-term operational costs and downtime.
Flexible and Adaptable Design: The modular and lightweight design allows for quick installation and can be custom-tailored to fit a wide range of tank dimensions and gas storage capacities, a necessity for diverse project scales and biomethane production rates.
