Indoor & Outdoor Hydrocab® –
Green hydrogen for heating

Do you want to convert surplus electricity, from a wind or PV plant into green hydrogen for heating?

We have customized solutions based Indoor or Outdoor HydroCab® with optional compressors and storage.

Shown here is our Indoor HydroCab®, a plug and play solution for small and medium sized H2 demands. It integrates up to five Enapter Electrolysers 4.0, no dryer is included in this configuration as most burners only require 99.9 % purity.

Each Enapter Electrolyser 4.0 is capable of producing up to 0.5 Nm³/h. The output volume of each Electrolyser can be set between 60 % and 100 %. The Indoor HydroCab combines up to 5 modules to a single plug and play cabinet.

The configuration shown uses Liquid Cooled Electrolysers which can be used for combined heat solutions.

A Water Tank Module can be installed which stores 38 l of deionized water. The WTM takes the space of one electrolyser and is needed when no direct water supply can be provided.

The solution is available in indoor and outdoor cabinets.

The system comes with a cloud based management system, and can be controlled from your laptop or phone

Do you need a bigger system? No problem, the system is scalable, ask us for a customized solution.
