CGON produce 3 different variants of the ezero range, each with different applications in mind from the ezero1 aimed at smaller engines, with the ezeroH1 targeted at larger vehicles such as small coaches and light goods vehicles in the 7.5 tonne range, all the way up to our ezeroH2 model for the HGV and bus market.

Each system comprises a tank with internal electronics control and a separate driver notification unit that keeps a check on the cell’s performance. The size of unit required depends on the amount of hydrogen required for the application.







A smart and compact wireless device which monitors your system. With just one push of a button, it will connect and inform you of your system’s operational status. Easy to use, easy to monitor.

The only maintenance required for the unit, is to top up with CGON’s electrolyte solution, when indicated on the wireless device. Each top up costs £8.40.

How we fit it


1. Test Emissions

Before we fit the ezero1, our installer will check your vehicle emissions to establish a baseline prior to fitting the unit.


2. Fit Unit

The installer will then mount the unit to the vehicle and attach the tubing and the sophisticated electronics.

Post testing

3. Tune & Test

After checking the system is completely functional, the installer will re-test emissions and optimise the amount of hydrogen being produced for your vehicle.

Here is a typical example of where the box fits in an engine.

Why it works

Once tuned the unit provides just enough hydrogen to generate an efficient combustion phase, burn all the fuel, rather than just a part of it and subsequently you get more power from fuel you actually use.

No ECU Adjustment

Here at CGON we do not adjust the vehicle's ECU (Electronic Control Unit). It has been found that if you edit ECU software it will increase emission levels. This was found during many hours of R&D and emissions testing. The by-product of lower engine emissions is increased fuel efficiency.

100% Recyclable

The ezero1 is 100% recyclable – the body is designed to be fully reused and since the precious metals do not degrade, they are fully reclaimable. Even the supply packaging is 100% recyclable.
