CGON produce 3 different variants of the ezero range, each with different applications in mind, from the ezero1 aimed at smaller engines, 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.
