$16.30 billion in 2025 is expected to rise to $23.53 billion by 2034, with the global automotive fuel tank market projected to grow at a 4.16% CAGR.
Lightweighting and regulation are the main drivers: automakers are shifting to plastic, multilayer tanks to cut weight, improve fuel economy and meet tighter evaporative-emission and safety standards.
Plastic tanks led by material in 2025, while passenger cars accounted for 68.5% of demand and 45-70 liter tanks made up 54.9%, reflecting broad use in mass-market vehicles.
North America held the largest regional share at 27.2% in 2025, supported by strong demand for larger tanks in pickups, SUVs and commercial vehicles.
The outlook is tempered by faster EV adoption and volatile resin costs, even as hybrid platforms and hydrogen storage systems create new niches for suppliers.
