Driving the future of mobility

With state-of-the-art hydrogen fueling technology

Linde Hydrogen FuelTech offers highly efficient fueling concepts according to your individual needs.

Hydrogen FuelTech GmbH

With Linde’s hydrogen fueling expertise under one roof, Hydrogen FuelTech aims to be your trusted partner in providing cutting-edge fueling technology. 

Cutting edge compression technology. The core of every hydrogen fueling station.

With technology from Linde, hydrogen infrastructure projects can be implemented in an efficient, sustainable and professional manner: We are the one-stop shop for hydrogen solutions – offering everything you need, from reliable H2 supply and cutting-edge fueling station systems to customized services, thus ensuring very low total cost of ownership per kilogram of hydrogen fuelled. With more than 160 hydrogen refueling stations worldwide equipped with our technology, Linde is the world leader for hydrogen fueling solutions. Our products provide high performance and reliability with a very low spatial footprint. And naturally, our solutions meet highest safety standards.

We aim to be your trusted partner. Together with our clients, we plan, design and build high-performance plants. We support you when it comes to commissioning, we supply gaseous (GH2) or liquid hydrogen (LH2) or produce it on site. And thanks to a dense network of maintenance and service technicians, we also ensure highest levels of safety and reliability. 

The compressing unit is the key component of a hydrogen fueling station. Here is where H2 stored at low pressure is compressed to up to 100MPa. Apart from hydrogen’s initial state – gaseous or liquid –, the fueling technology also depends on a range of other factors, for example the throughput and the type of vehicle to be fuelled. Linde offers suitable compression systems for the most varied requirements. With the ionic compressor and the cryo pump, we have two cutting-edge, self-developed and patented technologies in our portfolio. Both have impressed customers with outstanding reliability, little need for maintenance and high energy efficiency. Both systems can be optimized to meet your specific requirements. Furthermore, we have advanced our fueling technology to a point where we are now the first company worldwide that can produce small series of H2 fueling technologies.

Our technologies at a glance

The ionic compressor


In five steps, the ionic compressor condenses gaseous stored hydrogen to 100MPa. Its key characteristic is the eponymous ionic liquid, which does not bond with the gas. It acts both as a lubricant and coolant, and thus significantly reduces wear and tear. Additionally, the ionic compressor has fewer moving parts than a classic piston compressor. The liquid also increases the compressor’s energy efficiency due to better cooling and fewer dead spots during the compression process. 

As lubricants are not necessary with the ionic compressor, the hydrogen is not at risk of contamination. High levels of purity, for example as needed in fuel-cell applications, can be ensured. 

The cryo pump


The cryo pump operates with liquid hydrogen (LH2) at -253 °C. At this temperature, however, hydrogen cannot simply be suctioned in, which is why the pump uses a two-chamber system which is completely immersed in the cryogenic liquid. In the first chamber, LH2 from the storage tank is compressed to 0.6 MPa. The compression to 100MPa takes place in the second chamber. Subsequently, the temperature of the cryogenic gas is increased up to the fueling temperature of -40 °C. During all of these process steps, the high purity level of the hydrogen is maintained. 

In addition to its small footprint and high capacity, the cryo pump system minimises the fueling station’s energy consumption. Thanks to the application of cryogenic LH2, only 10–20 % of a gas compressor’s energy are needed for compression; the cooling system within the thermo management is omitted. Furthermore, the low amount of maintenance ensures low costs.

In a move to ready California for the next generation of fuel cell electric vehicles, Linde is outfitting True Zero’s newest retail hydrogen fueling stations with its highly efficient Cryo Pump 90 and the corresponding technology.

Customer quote

"This is a major leap forward in scaling up the adoption of fuel cell electric vehicles and improving our planet,” says Joel Ewanick, CEO of True Zero. “Linde’s technology provides a significant increase of refueling station capacity, and with that we see a path to retailing hydrogen fuel at cost parity with gasoline. This next generation True Zero station will ultimately enhance the customer experience as people refuel with clean hydrogen,” Ewanick says. “It will deliver more hydrogen to drivers of zero emission fuel cell vehicles each day, and it will refuel cars simultaneously to reduce customer wait times."
