Pressure Control & Hydrogen Applications

To efficiently create hydrogen as a renewable energy source, researchers and process engineers are constantly exploring the best possible process conditions for an optimal hydrogen production process. Pressure control is an important element in this research. As with all research, reliability and reproducability are important factors that contribute to the efficiency of research projects and the quality of research outcomes. The reliability and accuracy of the innovative products supplied and engineered by the team of Pressure Control Solutions are a very good match for research applications in general and electrolysis applications in particular!

PCS often serves customers in their attempts to optimize their hydrogen application and we are happy to thus play a part in so many sustainable initiatives.

Hydrogen & Electrolysis

A common way to generate hydrogen is electrolysis. While hydrogen emerges at the cathode, oxygen is produced at the anode. Although there would be no life on this planet without it, oxygen in high concentrations can be extremely dangerous. Especially when created at high pressure in combination with high flow velocities and a potential source of ignition. These factors can even cause stainless steel to burn (oxidize), causing hazardous situations. Read also this blog about the dangers of oxygen by Mitch Spronck!

Because of the many possibilities to customize our precision control products and to tailor the instruments to the particular needs of your application, we can always propose an instrument that fits your application best.

Material Options tailored to Electrolysis

Especially in case of electrolysis applications, the choice of wetted parts can make the difference. Copper alloys like brass are known to have a higher resistance to ignition and slower rate of reaction than for example Stainless Steel.

The beautiful brass back pressure regulator shown here is designed to operate at pressures between 2 and 200 bar with flow rates that start at almost zero flow up to hundreds of liters per minute, making it an ideal companion for researchers on their continuous quest to increase hydrogen production in electrolysis applications.
