Commercial Mobility First

H2ONE's first vehicle programme targets a three-wheeler engineering demonstrator.

Why three-wheelers

A practical first proving ground.

Compact power requirementKnown electric drivetrainHigh commercial utilisationRepeat-route operationDepot-return behaviourLower integration complexity than larger vehicle classes

The objective is to validate the complete DAFC power system under a realistic commercial duty cycle before considering larger vehicle platforms.

Vehicle architecture

Different primary energy source.

12 V Battery→Controls / Startup

Target The 10 kW net power system and 10 kg NH₃ storage are design targets. What "10 kW net" means → The inverter/motor controller, PMSM and drivetrain are carried over from the reference vehicle.

Power requirement

Cruise demand is not peak demand.

DC-bus power to hold a steady speed on a flat road Simulated
30 km/h~1.74 kW
40 km/h~2.73 kW
55 km/h~4.89 kW

A 10 kW architecture is intended to support more than steady flat-road cruising. Additional power is needed for:

accelerationgradientspayloadauxiliariestransient reserve
Gradients

Gradient demand explains the additional power capacity.

Hills are where the 10 kW goes.

Maximum sustainable speed at 10 kW DC-bus power Simulated
0° grade55 km/h
3° grade47.5 km/h
6° grade30.9 km/h
9° grade22.3 km/h
12° grade17.4 km/h

Steady-state equilibrium speeds from the calibrated 791 kg GVW road-load model. The 10 kW line is an available DC-bus power reference, not proof of sustained gradeability. No road test yet.
