Hydrogen Fuel Cells in Cars Without a Future? - An Analysis

Anyone still investing in fuel cell cars today has not grasped the seriousness of the situation, says consultant Andreas Radics. He sees no global markets for the technology - not even for trucks.

It is something like the eternal undead among alternative drive systems. For decades, the idea of the fuel cell as a climate-friendly technology of the future has been popping up again and again. Now, for example, Hyundai is once again drawing attention to the mobile power plant with the second generation of the Nexo. This produces electricity for electric motors on board the car from hydrogen in a process known as cold combustion, emitting nothing other than water vapor. Alongside the Toyota Mirai and a small series of the BMW X5, which also uses Mirai technology in cooperation with Toyota, the Nexo is the only passenger car to use this drive system. And there is also little choice in Europe when it comes to commercial vehicles: Hyundai has the Xcient heavy-duty truck in fleet testing, especially in Switzerland, Mercedes at least has prototypes of the converted Actros running and Stellantis has a few vans with built-in hydrogen converters.

The lack of success is not due to the technology itself, as a look at the new Nexo shows: With a tank for seven kilos of hydrogen, it has a range of 700 kilometers, drives at speeds of up to 179 km/h with 204 hp and when the tank is empty, it takes less than five minutes to refill. Even the most powerful e-architecture can't keep up with that. And while previous fuel cell vehicles had a trunk full of technology, the space available in the 4.75-metre-long Nexo is at least as good as an electric SUV, with plenty of knee room in the rear and up to 1,719 liters of storage space. The Koreans can now even offer a trailer coupling.

Lack of infrastructure

Drive far, refuel quickly - at first glance, the fuel cell is therefore a pleasing alternative to battery-electric driving that is suitable for everyday use, because many of the disadvantages of the classic electric car can be overcome. But the first impression is deceptive. The problem for the customer starts with the infrastructure. After more than three decades of research and pre-series production, during which the fuel cell came onto the road, at least in homeopathic numbers, there are only 100 filling stations in Germany. And instead of closing the huge gaps in the network, the first of these are already being dismantled. And even if the price is generally set arbitrarily and in no way reflects the gigantic development costs and the small quantities, fuel cell vehicles are by no means a bargain. Not to mention the loss of value and resale problems.

The problem is even more serious for the manufacturer than for the customer. "In these times of transformation, capital and know-how resources are too scarce for the industry to be able to further develop every alternative drive system," says Andreas Radics from Munich-based strategy consultants Berylls by AlixPartners. "And now that the world has apparently decided in favor of the battery and at best accepts the range extender as a variant, every euro invested in the fuel cell is a waste," judges the expert: "None of the major sales markets has even a rudimentary strategy to drive forward the introduction of this technology in passenger cars."

Anyone who spends money on fuel cell cars today has not yet grasped the seriousness of the situation," Radics is convinced: "The requirements for a nationwide infrastructure are currently no longer affordable, even for Germany. In the current situation, unsettling customers about the future viability of their car drive is certainly the least effective measure.

Millions in subsidies wasted

Radics also advises society to make better use of its resources and stop supporting the fuel cell. With a shake of the head, he talks about the millions of euros in funding that are being spent on barely more than a handful of vehicles. For example, there are 1.8 billion euros in the EU pot for hydrogen infrastructure, of which 455 million was distributed for hydrogen infrastructure projects in Europe in February - with no prospect of this infrastructure ever being used.

Instead of at least slowly increasing, the registration figures for fuel cell vehicles are continuing to fall: while 900 cars with hydrogen technology were sold in 2022, the figure was only 260 in 2023 and just 150 last year. Things are no better worldwide: Global figures have fallen from 15,000 to 8,800 and most recently to 4,800.

Many see better opportunities for the technology in commercial vehicles because there is more space for the fuel cell and the heavy batteries use up the payload of the trucks. But here too, the figures speak for themselves, says Radics: "Not many more than 7,000 new fuel cell trucks and vans are put on the road every year - worldwide.

No hope in China

Not even a look at China gives us hope. Yes, there are also researchers and companies there who believe in the fuel cell. And 4,000 new fuel cell trucks are registered in China every year, Radics admits. But in the same period, 75,000 battery-electric trucks are put on the road, he says, which immediately negates the success of the project.

And as if that wasn't hopeless enough, there is also a lack of fuel. "Because there is not enough green hydrogen to make it worthwhile to build an infrastructure," says the Berylls expert. So it's no wonder that a kilo of hydrogen now costs between 16 and 18 euros. The expert is convinced that even e-fuels are cheaper and better. To be competitive, it should only cost half as much.

It is still far too expensive, hydrogen is not sufficiently available, if it is, then not from renewable energies and too expensive, and there is also no infrastructure to distribute it. "As promising as the fuel cell may have been in the beginning, it has lost the race against the battery in cars," says Radics. The fuel cell is a horse that has long been ridden to death. Anyone who continues to saddle it up these days has not recognized the signs of the times and cannot be successful."
