Water electrolysers / hydrogen generators

With 3,500+ electrolysers installed worldwide, Nel is a leader in both alkaline and PEM water electrolysis. Since 1927, our R&D-driven innovations have set industry benchmarks for reliability, efficiency, and performance.

Our scalable, modular electrolysers deliver flexible solutions for industrial, transport, and Power-to-X applications.

PEM Electrolyser – PSM Series

MW-class PEM Stack Module (PSM) for on-site hydrogen generation utilizing a modular containerized design for ease of installation and integration with the balance of plant

PEM Electrolyser – MC Series

In situations where plant space is at a premium, customers may want to site their electrolysers outside. At other times customers may want to configure an electrolyser for a more turnkey operation. MC electrolysers deliver the M Series platform in a containerized form for easy outdoor installations. Typical applications include renewable energy storage, industrial process gas, and hydrogen fueling.

Atmospheric Alkaline Electrolyser

Elevate your industrial processes with one of the world's most energy-efficient electrolysers, designed to meet the demands of the future.

PEM Electrolyser – C Series

The C Series electrolysers are ideal for a variety of industrial applications. Producing up to 30 Nm³/h of hydrogen gas at 99.999+% purity, these units replace the need for hydrogen tube trailers or liquid hydrogen storage.

PEM Electrolyser – H Series

H Series electrolysers offer turnkey solutions for small-scale applications requiring up to 6 Nm³/h of hydrogen gas at 99.9995% purity. These units make a minimal impact to facility floor space, are easy to maintain and can be installed within hours.

PEM Electrolyser – S Series

Producing high purity hydrogen of 99.9995% at up to 1.05 Nm³/h, S Series electrolysers replace the need for pressurized hydrogen cylinders in a variety of industrial processes. Each unit is low maintenance, compact, quiet, and can be installed within hours virtually anywhere in a facility.
