The shift from fossil fuels to hydrogen, CNG, and renewable gases requires advanced storage technologies. Epoxy resins, when used as the matrix in composite pressure vessels, provide the necessary mechanical integrity, leak prevention, and lightweight properties needed for alternative fuel adoption.

According to Stratview Research, the epoxy resin market in pressure vessels for alternative fuels is likely to grow at a healthy CAGR of 16.9% during 2021-2026 to reach USD 49.7 million in 2026.
