Outdoor HydroCab® – Green Hydrogen for District Heating

Do you need green hydrogen to power district heating?

Shown here is a typical solution for a customer requiring 99.9% purity H2, in an outdoor cabinet, which uses surplus PV electricity to generate H2, for later use in a district heating system.

This solution shown uses a high-quality 19″ cabinet system includes a heating, and ventilation system, with five Electrolysers.

The hydrogen production can be specified from 1 kg/24h hydrogen up to 5 kg/24h hydrogen per cabinet.

Other installation modules, such as a water purification system, compressors, a water tank module and fuel cells with different power levels, are also available for the H2 Core System.

The system comes with a cloud based management system, and can be controlled from your laptop, mobile app, via the main panel, Modbus or via external PLC.

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