Swagelok Hydrogen Applications

Why is Hydrogen vital for a greener future?

Reducing harmful emissions is a topic that is growing, and is not going away anytime soon. The usage of hydrogen has already started and is gradually increasing. The versatility and environmental benefits is widely recognized, and is gaining traction towards a greener future.

So far hydrogen is used in several industrial processes. Hydrogen is a fundamental building block for the manufacturing of ammonia, hence fertilizers, and methanol and of many polymers. In addition, it is used in the manufacturing of intermediate oil products in refineries, blending into natural gas, and as an alternative fuel. 

In energy, most hydrogen is used through Fuel Cells (FCs). A fuel cell is an electrochemical device that combines hydrogen and oxygen to produce electricity, with water and heat as by-products. In its simplest form, a single fuel cell consists of two electrodes - an anode and a cathode - with an electrolyte between them. At the anode, hydrogen reacts with a catalyst, creating a positively charged ion and a negatively charged electron. The proton then passes through the electrolyte, while the electron travels through a circuit, creating a current. At the cathode, oxygen reacts with the ion and electron, forming water and useful heat.

Customer Success

Our Customer Successes

Here is a collection of our customer's testimonials related to hydrogen applications and how Swagelok was able to help with their operations, and provide high quality, reliable fluid system components.



Infrastructure applications include the dispensers, storage cylinders, compressors, separators, and pressure control devices that make up the station, as well as the hydrogen tube trailers that bring the hydrogen to the stations. Components in these locations must be hydrogen-compatible but may not require specific certifications. 


On-Vehicle Applications

On-vehicle applications include light-duty (car and van), heavy-duty (bus and truck), rail, ship, and aerospace. Specific testing is required to achieve this certification, including corrosion resistance, endurance, hydraulic pressure cycle testing, and external leakage testing.
