Definition:
An internal combustion engine designed or modified to burn hydrogen gas as fuel, producing power through the ignition of hydrogen in air.
Key Components:
- Hydrogen injectors
- Spark ignition system
- Engine control unit (ECU) tuned for hydrogen
- Modified intake/exhaust systems
Use Cases/Industries:
- Heavy-duty transportation
- Marine applications
- Off-road machinery
Advantages:
- Zero carbon emissions at point of use
- Potential retrofit of existing ICEs
- Rapid refueling
Challenges:
- NOx emissions due to high combustion temperatures
- Hydrogen storage and delivery complexity
- Lower energy density per volume
Related Terms:
Internal Combustion Engine, Hydrogen Fuel, NOx Emissions
Example:
A logistics company retrofitted diesel engines with hydrogen combustion technology, reducing CO₂ emissions without replacing entire fleets.
