Traditional steel cylinders often weigh 30-40% more than necessary, inflating shipping expenses. For fleets of 100+ vehicles, this can add $50,000+/year in fuel and transport costs (Source: IEA Global Gas Report 2025).
Non-standard cylinders fail DOT, CE, or ASME certifications, leading to customs rejections or costly rework. In 2024, 12% of CNG cylinder shipments to the EU were delayed due to non-compliance (Source: IRENA Geopolitics of Energy Transformation).
Cheap cylinders corrode within 3-5 years, while premium options exceed budgets. 68% of procurement managers report struggling to find a balance (Source: Fortune Business Insights 2025).
→ Solution: Shijiazhuang Enric’s 20 kg CNG cylinders address all three—see how below.
