Reasons to implement HRX


Utilising state of the art hydrogen fuel cells to combine the best elements of both hydrogen and battery technology


Modular buildup allows for changes in battery and hydrogen storage capacity allowing range to be increased.


Fuel cell power system can be scaled to match the needed application


Always drawing down the battery first, the system only uses stored hydrogen when you need the range.

Cost Efficient

Installing HRX significantly reduces weight costs compared to an equivalent battery pack.
