Applications

Pressure vessels are widely used in hydrogen fuel-cell vehicles, CNG-powered cars, onboard air-brake systems, air suspension systems, and thermal management loops in electric vehicles. In hydrogen and CNG applications, these vessels function as primary storage tanks, ensuring safe energy delivery to the powertrain. In EVs, they support cooling operations, heat pumps, and refrigerant handling systems, contributing to improved vehicle performance and reliability.

Trends

Key market trends include rapid advancements in lightweight composite pressure vessels, driven by the need to improve vehicle range and reduce emissions. Hydrogen mobility is emerging as a major growth driver, leading to increased demand for high-pressure (700 bar) storage systems. Innovations in manufacturing—such as filament winding, nano-reinforced resins, and automated quality testing—are improving vessel performance and production efficiency. Regulatory focus on safety and sustainability is encouraging development of recyclable and high-integrity pressure vessel designs.
