M Series Containerized

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.

A Series

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

M Series

The M Series provides fast response times and production flexibility making it ideal for hydrogen generation utilizing renewable power sources. With minimal maintenance and siting requirements, M Series electrolysers can produce up to 4,920 Nm³/h of hydrogen gas at 99.9998% purity on-demand. Featuring a scalable modular design that can be containerized, these systems offer solutions that are well-suited for a variety of industrial, fueling and renewable energy applications.

C Series

The C Series electrolysers are ideal for a variety of industrial applications. Producing up to 30 Nm³/h of hydrogen gas at 99.9998% purity, these units replace the need for hydrogen tube trailers or liquid hydrogen storage.
