Hydrogen engine cleaning
Give your combustion engines a new lease of life

At H2CCM, we offer a 100% hydrogen-based engine decarbonisation service.
Why descale an engine?
When fuel is burned, the engine generates carbon deposits.
These deposits act like ‘cholesterol’: they reduce power, increase fuel consumption and accelerate wear and tear.
Our process
We inject hydrogen into the engine’s air circuit. The carbon deposits are dissolved and evacuated through the exhaust.
Zero chemicals
No dismantling required
Compatible with petrol and diesel
Suitable for all types of engines (500cc to 75,000cc)
The result? Your engine breathes better, consumes less fuel and pollutes less.

The tangible benefits
Immediate financial savings
Reduce your fuel consumption by 6% to 15% with an optimised engine.
For a commercial fleet, this represents thousands of pounds saved each year.
Performance restored
Your engine regains its original torque, flexibility and power.
Reduced smoke, smoother operation, easier starting.
Less pollution
Less CO₂, fewer fine particles, reduced environmental impact.
An ideal solution for incorporating your company into a concrete CSR approach.
Preventive maintenance
Less clogging = fewer breakdowns.
The treatment protects your engine and extends its service life.
How does an H2CCM intervention work?
Discover our hydrogen engine decarbonisation process, designed to revitalise your engine efficiently and ecologically.
1
Rapid diagnosis (optional)
We assess the condition of your engine, carry out a test and analyse the symptoms to determine the appropriate treatment.
2
Hydrogen decarbonisation
We inject a mixture of hydrogen and oxygen for 45 to 180 minutes (depending on the engine capacity), without the need for dismantling.
3
Personalised assessment
We explain the results obtained, provide recommendations and offer personalised follow-up.
