Valves for hydrogen production

Emission-free hydrogen production for a greener future

Neles is your valve partner for greener hydrogen processes. Our long experience and comprehensive portfolio cover the majority of applications in the industrial use of hydrogen. Many of the world’s leading industrial gas companies already rely on Neles valves for reliable performance. Also, many downstream end users turn to us when selecting valves for demanding H2 applications.

Hydrogen production

Green hydrogen refers to H2 produced from water utilizing surplus renewable energy by the process of electrolysis. The first step in the green hydrogen process is typically electrolysis, a process where surplus electricity is used to create hydrogen by splitting water. Another promising way to produce hydrogen in a sustainable way is methane pyrolysis where methane is cut either catalytic or by plasma in hydrogen and solid carbon. Our valves perform well under the pressure and temperature requirements present in these processes. Another way to decarbonize emissions in process industries is to capture the produced carbon dioxide. Hydrogen produced in this way is called blue hydrogen.

Today, electrolyzers, the devices used in production typically utilize one of two technologies; low-pressure electrolysis or high-temperature electrolysis. Technological development has already seen us move up to large-scale 20MW electrolyzers, but 100MW units are not too far in the future either. Our valves portfolio already fulfills the requirements of electrolysis applications as for the PEM, AWE or SOEC electrolyzers of both today and tomorrow

Going green with reliable valves

As the significance of responsible and sustainable industrial processes increases, the role of green and blue hydrogen as carbon-neutral fuel produced from surplus renewable energy or through CO2 removal, respectively, will continue to grow. Did you know that Neles offers a wide range of high-quality valve solutions for green and blue hydrogen? Today Ville Kähkönen, Head of Industry, Power to X and Gases, and Taneli Naukkarinen, Director of Core Industries, EMEIA Market Area, talked about green hydrogen and oxygen, and how Neles’ long experience in the industry can help customers on their path to a greener future.

Going green is a global megatrend

Going green is a global megatrend that can be seen in all industries and everyday life in general. The same applies to hydrogen. We are experiencing a shift from the traditional gray and brown hydrogens to new emission-free green fuels. With decades of experience in industrial gas and hydrogen applications, Neles is equipped to serve customers taking the leap into both blue and green hydrogen.

Valve solutions for green hydrogen

Neles produces a wide range of segment, butterfly, globe and other valves that have proven themselves in long-lasting service over many decades. Our valves deliver superior performance in low-pressure electrolyzers as well as in those that are subject to high temperatures reaching up to 700˚C. All Neles products are supported by our comprehensive service offering and service network.

Fast and accurate valve control

Electrolyzers must typically react very quickly to variations in supply when it comes to renewable energy. This means that internal processes require fast adjustment, and the valves need to deliver accurate control with quick response times. Our positioners are excellent for providing fast and extremely accurate valve control.

Addressing the needs of new technologies

New electrolysis technologies are also creating the need for valves that can ensure both high capacity and low-pressure losses respectively. Our segment valve offering and the L-series butterfly valves with their 2-shaft design are particularly strong performers in this area.

Tested and proven performance

All of our valves are designed for long-lasting tightness, minimized fugitive emissions and low differential pressures. We want each of our valves to be environmentally friendly, energy-efficient and reliable in operation. We provide field-proven designs and tested performance in each and every valve delivery.
