The global energy landscape is undergoing a profound transformation, with an accelerating shift towards renewable natural gas (RNG), or biomethane. As a purified and upgraded form of biogas, biomethane offers a sustainable, carbon-neutral alternative to fossil natural gas, capable of being injected into national gas grids, used as vehicle fuel, or directly for heat and power generation. This high-value, high-purity renewable resource demands equally high-performance storage solutions. The journey from raw organic waste to clean biomethane is a complex process, and the final, critical step—secure and efficient storage—is paramount to maximizing its value and ensuring a consistent supply. This calls for biomethane storage tanks that offer absolute gas-tight integrity, exceptional durability, and unwavering reliability, specifically engineered to contain this refined, valuable gas. This is precisely where Shijiazhuang Zhengzhong Technology Co., Ltd, globally recognized as Center Enamel, stands as a premier China biomethane storage tank manufacturer. We deliver precision-engineered, high-quality tanks that form the indispensable core of efficient, environmentally sound, and highly productive biomethane projects across diverse applications worldwide.
For over three decades, since its establishment , Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) has consistently pioneered advancements and established the highest benchmarks within the bolted steel tank industry. We have firmly positioned ourselves as a global authority in critical liquid and gas containment, particularly for the most demanding industrial and environmental applications where gas-tight integrity, chemical resistance, and structural reliability are paramount. Our distinguished standing as a leading China biomethane storage tank manufacturer is a direct outcome of our profound technical acumen, our unwavering adherence to the most stringent international quality, safety, and environmental standards, state-of-the-art production facilities, and a deep, practical understanding of the precise requirements for high-purity biomethane storage.
As the first manufacturer in China to produce Glass-Fused-to-Steel (GFS) tanks, and holding more than 20 enameling patents, Center Enamel has consistently demonstrated its commitment to innovation and engineering excellence. We don't just supply biomethane storage tanks; we engineer mission-critical containment solutions specifically optimized for the precise requirements of biomethane. This ensures unparalleled gas-tight integrity, minimizing valuable methane loss to the atmosphere, superior operational efficiency, and significant contributions to long-term energy sustainability and carbon emission reduction across the globe. Our extensive track record in supporting complex projects, spanning over 100 countries and across six continents, profoundly underscores our unparalleled capability and unwavering commitment to global clean energy initiatives and environmental stewardship.
Fusion Bonded Epoxy (FBE) coated steel tanks, particularly those utilizing Center Enamel's proprietary, advanced FBE coating technology, represent an optimal and widely adopted solution for safely and efficiently storing purified biomethane. Unlike conventional concrete structures, which are porous and susceptible to gas leakage, or traditional welded steel tanks that require extensive and often hazardous on-site fabrication, our FBE biomethane storage tanks embody unparalleled gas-tight integrity, resilience, and environmental protection—qualities that define their expert status for containing high-purity gas.
Center Enamel's tanks are precision-engineered and meticulously manufactured under the most stringent quality controls within our expansive, 150,000 square meter factory environment. This process has been refined over many years of unparalleled industry experience, continuous research and development, and real-world application insights into the specific challenges of biomethane production and storage. It involves applying a specialized, high-performance epoxy resin powder to flawlessly prepared, high-grade steel panels. Through a precise thermal fusion bonding process, this powder melts and chemically bonds to the heated steel surface, creating an incredibly tough, uniformly applied, and intrinsically impermeable protective layer.
This factory-applied coating is paramount for effective biomethane storage. It forms an inert, exceptionally durable, and non-porous barrier that offers superior chemical and abrasion resistance. While biomethane is significantly purified, the FBE coating provides an extra layer of protection against any trace impurities and ensures the long-term integrity of the tank. Crucially, the FBE coating ensures absolute gas-tight containment, which is vital for preventing valuable methane emissions, maximizing biomethane capture for energy generation, ensuring safety, and maintaining stringent regulatory compliance. This resistance actively prevents tank degradation, ensures the long-term structural integrity of the vessel, and critically minimizes costly downtime and environmental liabilities, solidifying its position as the expert choice for essential biomethane infrastructure. Our FBE tanks are designed to meet the rigorous demands of low to medium pressure storage environments common in biomethane applications, where gas-tightness is key.
