Hydrogen Internal Combustion Engine (ICE)


Some vehicles with an internal combustion engine (ICE) are specially designed to run on hydrogen. While hydrogen infrastructure is still ramping up, current hydrogen ICE vehicles are designed to run on either gasoline or liquid hydrogen.


Hydrogen ICE vehicles provide a good transition to fuel cells and result in fewer smog and greenhouse gas emissions than their gasoline counterparts.

Hydrogen Production

Hydrogen can be produced from many domestic feed stocks, such as natural gas and renewable resources like water, using electrolysis. While the most common method of making hydrogen, using natural gas reformation, results in fewer smog-forming and greenhouse gas emissions than traditional vehicles, California is working to increase use of renewable production sources.


Automakers previously conducted demonstration projects with this technology but have no near term plans to market hydrogen ICE passenger vehicles.

California has 13 research hydrogen fueling stations, 9 public stations and an additional 18 that have been funded and are expected to be operational in the next few years. Below are some resources for finding fueling stations for hydrogen fuel cell cars:
