Hydrogen engine cleaner that optimizes the operating economy of your fleet


All companies with a fleet know that taking a vehicle out of service is expensive because a particulate filter needs to be cleaned or replaced. With HYDRIVE ProCareTM, which prolongs the life of your particulate filter and lets you run longer on the liter.

HYDRIVE ProCare is a 100 percent environmentally friendly technology that cleans gasoline and diesel engines from the inside with hydrogen. This makes both engines and particle filters more efficient, while the pollution of the vehicle is reduced.

Significantly more traction at Keolis

Keolis, a company based in Denmark, which is the leading supplier of public transport in the country and internationally, initially tested HYDRIVE on 15 of their buses. Especially newer buses need a loving hand because more environmentally friendly engines and filters stop. Workshop Manager Anders Farre Nielsen says:

 "Previously, we replaced two to four filters a month, which is equivalent to thousands of dollars. Since HYDRIVE has started to come here, we have not replaced a single filter. The back pressure in the filters has also improved and drivers report that more vehicles have gained significantly more traction. "

“One of our trucks has gone from driving 2.9 km to 3.4 km per hour. liter on average. In a small year, it has run over 50,000 km without any problems - and so we usually clean or replace particle filters every 20,000 km.”
