Hydrogen tanks after 15 years: a real issue, not a death sentence

As the first generation of hydrogen cars ages, a new question comes into focus. The concern is not the fuel cell, but the high-pressure hydrogen tank. Under the international UN/ECE R134 standard, these tanks are currently approved for 15 to a maximum of 20 years. After that, the operating approval lapses and the tank must be replaced to keep the car on the road. For early models such as the Toyota Mirai, the Hyundai ix35 Fuel Cell and the Honda FCX Clarity, that replacement can run into the tens of thousands of euros, sometimes more than the car's residual value. It is a genuine issue that the sector takes seriously.

What the coverage makes of it

Dutch outlet AD headlined that many hydrogen cars are "written off" after 15 years. The core is factually correct: the standard exists, the timeframe is right, and replacement is expensive. But the framing is misleading. The article presents a temporary, solvable regulatory issue as a fundamental death sentence for hydrogen, which it is not.

Three things are missing from that story. First: the earliest tanks only reach their end date around 2030-2035, as the Mirai launched in 2014. There are years to get regulation and processes in order. Second: the numbers are small. It concerns a few thousand cars across Europe, not a mass problem. Third, and the biggest omission: recertification of pressure vessels is not science fiction, but established practice in other sectors.

Recertification has existed for a long time

Pressure vessels do not automatically have to be scrapped when an inspection term expires. In sectors such as CNG vehicles, diving cylinders and industrial gas cylinders, tanks are periodically re-inspected and recertified, after which they may continue in service. Such re-inspection includes, for example, a pressure test and a thorough inspection. In the United States, certain composite vessels already have recertification at fixed intervals.

For hydrogen passenger cars in Germany and most EU countries, however, a certified recertification process is still lacking. That is precisely the point: not that it is technically impossible, but that the procedure has not yet been established. As long as it does not exist, replacement is legally the only option, and that makes it needlessly expensive. Mobility experts recently flagged the same on LinkedIn: the industry must look beyond vehicle sales and address total cost of ownership across the full lifecycle.

The context the coverage leaves out

Despite the small numbers, global fuel-cell vehicle registrations grew by more than 24 percent in 2025. Manufacturers such as BMW and Hyundai continue to invest in hydrogen mobility; BMW will bring a series-production hydrogen model to market from 2028. The technology is not standing still.

Moreover, the lifespan question applies more broadly than to hydrogen alone. Battery-electric cars also experience wear, in their case degradation of the battery pack. Every drivetrain has its own lifecycle question; that is no argument against hydrogen, but a normal part of a maturing technology. Alongside battery-electric, hydrogen remains a zero-emission solution, with fast refuelling and long range as strong points.

What needs to happen

The solution is clear and achievable: a standardised recertification programme that keeps healthy tanks in service longer after inspection. That lowers total cost of ownership, keeps hydrogen cars affordable in their second life, and prevents valuable materials such as carbon fibre from being written off unnecessarily. Using resources sparingly argues precisely for reuse and recertification rather than replacement.

The tank lifespan question deserves attention, but not the conclusion attached to it. It is a solvable regulatory issue in a young market, not proof that hydrogen has no future. Regulators and manufacturers now have both the time and the technical basis to get it right.
