The production of biomethane, or Renewable Natural Gas (RNG), has become a cornerstone of the global renewable energy transition. As a high-purity, carbon-neutral fuel, biomethane offers a direct path to decarbonizing natural gas grids and transportation. The conversion of raw biogas into this high-value product is a complex process, and at the end of this chain, secure and reliable storage is paramount. A dedicated Biomethane Storage Tank provides the final, crucial buffer, ensuring a consistent supply of RNG for injection or utilization. This technology is vital for the economic viability and operational stability of any modern Biogas Plant. As a leading China Biomethane Storage Tank Manufacturer, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) is at the forefront of providing these advanced, durable, and reliable storage solutions.
With over 30 years of specialized expertise in providing advanced containment systems, Center Enamel has established itself as a trusted global authority. Our reputation as a premier China Biomethane Storage Tank Manufacturer is built on a deep understanding of the unique demands of biogas and biomethane projects.

By offering a proven, robust storage solution, we provide a streamlined and highly cost-effective path toward a more sustainable and profitable future.
A modern Biogas Plant that produces biomethane is a multi-stage facility. Raw biogas is first produced in anaerobic digesters, then sent to a purification and upgrading system to remove carbon dioxide, hydrogen sulfide, and other impurities. The final product is high-purity biomethane. However, the upgrading process may not always align perfectly with the gas grid's injection schedule or a fleet's fueling demands. This is where the Biomethane Storage Tank plays its critical role.
The primary functions of a biomethane storage tank are:
Buffering Production and Demand: The tank acts as a final buffer, storing the upgraded biomethane until it is needed. This allows the biogas upgrading equipment to run continuously and at peak efficiency, independent of the external demand for the final product.
Providing a Continuous Supply: The tank ensures that a consistent, high-pressure supply of biomethane is available for injection into the natural gas grid or for use in a vehicle fueling station. This reliability is crucial for meeting contractual obligations and ensuring uninterrupted operations.
Securing High-Purity Gas: The tank's leak-proof design and corrosion-resistant materials ensure that the high-purity biomethane is not contaminated or lost. This protects the quality of the final product and its market value.
Ensuring Operational Stability: By providing a stable buffer, the storage tank protects the entire plant from downstream disruptions, such as grid maintenance or unexpected drops in demand. This ensures the plant's economic viability and operational safety.
By providing this crucial buffer, a Biomethane Storage Tank is an indispensable component that enables a Biogas Plant to operate with maximum efficiency and profitability.
Center Enamel's Biomethane Storage Tank is engineered using our signature Glass-Fused-to-Steel (GFS) technology. GFS tanks are recognized globally as a superior storage solution for the demanding conditions of the biogas industry. The core of this technology involves fusing a proprietary enamel coating to steel plates in a high-temperature furnace, creating a material that combines the strength of steel with the chemical resistance of glass.
The key features of our GFS tanks that make them ideal as a Biomethane Storage Tank are:
Unmatched Corrosion Resistance: The smooth glass coating is inert and provides a hermetic barrier against the corrosive compounds found in biogas, such as hydrogen sulfide, and the acidic conditions of the digester itself. This ensures an exceptionally long service life with minimal maintenance.
Rapid, Safe Installation: GFS tanks are built using a modular design. The prefabricated plates are bolted together on-site, a process that is significantly faster and safer than traditional welded tanks. This reduces construction time and costs, and allows the tank to be installed in remote locations.
Leak-Proof Integrity: The tank's bolted construction, combined with a specialized sealant, creates a robust and leak-proof structure, which is essential for storing high-pressure biomethane and preventing valuable gas losses.
Low Maintenance: The durable, non-porous glass surface is highly resistant to abrasion and requires virtually no maintenance, eliminating the need for periodic repainting or recoating.
This proven technology guarantees that a Center Enamel Biomethane Storage Tank provides a reliable, long-term asset for your Biogas Plant.
Our Biomethane Storage Tank offers a range of significant benefits that make it an essential investment for any facility producing RNG:
Exceptional Longevity: The Glass-Fused-to-Steel technology provides a service life of over 30 years, far exceeding that of conventional steel or concrete tanks. This longevity translates into a low life-cycle cost and a superior return on investment.
Optimized for Safety: The GFS tank's robust construction and precise engineering ensure a safe containment solution. They can be equipped with safety features and are designed to withstand the pressures and stresses of storing biomethane.
Cost-Effective Installation: The modular design of our GFS tanks allows for a smaller construction footprint, requiring less heavy machinery and labor. This significantly reduces overall project costs and streamlines the construction timeline.
Versatility and Customization: GFS tanks can be custom-engineered to meet specific volume and height requirements, ensuring a perfect fit for any Biogas Plant layout. They can be expanded or relocated in the future, providing unparalleled flexibility.
Proven Performance: Our GFS technology is internationally recognized and has been implemented in thousands of projects worldwide, demonstrating its reliability and effectiveness in a wide range of climates and applications.
