We can confirm and assure clients that they will achieve at minimum 10% fuel reduction. In some cases it will be more. Maximum fuel savings will be achieved with driver training, driver attitude and conduct. This is because as hydrogen is injected then the driver will immediately notice the increase in power. If he/she then reduces their diesel output (depress the accelerator pedal less or more as required) then maximum savings are achieved. However, if on the other hand the driver notices the increase in power therefore he accelerates even more, then the savings are reduced. We are guaranteeing that if they don’t achieve the fuel reduction as indicated then we will remove the system, return their vehicle to its’ original form and fully refund the cost.
