Hydrogen Internal Combustion Engine Vehicles (HICEVs) are another type of hydrogen vehicle that utilizes hydrogen as a fuel source for an internal combustion engine, like traditional gasoline-powered vehicles.
One of the advantages of HICEVs is their ability to use existing infrastructure. Unlike FCEVs, which require dedicated hydrogen refueling stations, HICEVs can be refueled at traditional gasoline stations. It makes them a more convenient option for consumers as they can easily find a refueling station.
In addition, HICEVs produce significantly fewer emissions compared to conventional gasoline-powered vehicles. While they still emit greenhouse gases, the emissions from a HICEV are lower due to the combustion of hydrogen, which results in water vapor as the main byproduct. It makes HICEVs a cleaner alternative to traditional gasoline-powered vehicles, helping to reduce air pollution and mitigate climate change.
However, there are some disadvantages to consider. One drawback is the lower energy efficiency of HICEVs compared to FCEVs or BEVs. Converting hydrogen into mechanical energy in an internal combustion engine is less efficient than using a fuel cell or electric motor. HICEVs may have lower fuel economy and require more hydrogen to achieve the same driving range.
