The hydrogen combustion engine has a peak at high load and can achieve similar efficiency levels as a hydrogen fuel cell. [34] From this, one can deduce that hydrogen combustion engines are a match in terms of efficiency for fuel cells for heavy duty applications. Efficiency decreases for small internal combustion engines.

Hydrogen internal combustion engine cars are different from hydrogen fuel cell cars. The hydrogen internal combustion car is a slightly modified version of the traditional gasoline internal combustion engine car. These hydrogen engines burn fuel in the same manner that gasoline engines do; the main difference is the exhaust product.
Bivalent engines can also use hydrogen fuel, as demonstrated by the BMW Hydrogen 7 using a bivalent V12 H7 Series engine. The engine itself is similar to a regular gasoline combustion engine, except for the fuel injection system. When a BMW Hydrogen 7 is running in gasoline mode, the fuel is injected directly into the cylinders, but when the ...

In December 2023, NamX announced that they would update the HUV design to use a hydrogen internal combustion engine manufactured by Solution F. [11] This combustion engine emits less than 1g of CO 2 per 100 km (mainly through engine oil combustion residue). [12] The engine uses dihydrogen (H 2 or pure molecular hydrogen) as a fuel.
Hydrogen fuel enhancement is the process of using a mixture of hydrogen and conventional hydrocarbon fuel in an internal combustion engine, typically in a car or truck, in an attempt to improve fuel economy, power output, emissions, or a combination thereof.
