HXB-V1 SYSTEM BOUNDARY

HXB-V1 produces hydrogen
and connects to the equipment your site requires.

HydroXpand supplies HXB-V1 and helps review its connections to site utilities and downstream equipment. A modular dryer is in development; for immediate needs, we can recommend a suitable partner product. Compression, storage and end-use equipment remain within the customer or integration partner scope.

Choose your supply boundary

Choose HXS-2 when your team
will build the BoP.

Start with HXB-V1 for an integrated system, HXS-2 when your team will build the BoP, or research cells and electrodes when the project begins with evaluation.

01
Will your team build and integrate the BoP?

Integrated system or stack: where the supply boundary sits

HXB-V1 reduces the equipment your team must integrate. Choose HXS-2 when power, circulation, separation, controls and safety are already in your scope.
