Leading companies choose Nel.

From research labs to industrial-scale production, Nel’s complete electrolyser range and century of experience ensure your hydrogen project succeeds.

Proven at scale

From NREL's research installations to Ovako's 20 MW steel decarbonization, Nel systems operate at every scale. Our complete range means you work with one partner from pilot to production.

Factory-built speed

Containerized MC Series and modular A-Series reduce deployment timelines vs custom builds. Pre-integrated systems arrive site-ready, minimizing field work and commissioning time.

Global manufacturing

1.5 GW annual capacity with facilities in Europe and the USA ensures supply security. Our scale means parts availability, service network, and confidence in support and after-care.

100 years of excellence

Since 1927, Nel has pioneered hydrogen technology. 7,000+ stacks in 80+ countries prove our commitment to reliable, field-proven solutions.

"This is the very first hydrogen production project using nuclear power in Korea and we needed to have the most reliable electrolysis technology. There is no doubt that Nel's technology can meet our expectation."
Byung Soo Lee
Head of Energy Solution Business Unit, Samsung C&T
