Electric vehiclesBattery electric vehicle (BEV)Battery electric vehicles (BEVs), also known as electric cars, are powered solely by electricity. They use rechargeable battery packs to store the energy, which is then used to power the electric motor that drives the vehicle. BEVs have zero tailpipe emissions and can provide significant fuel economy benefits over gasoline-powered vehicles. However, they do require a source of electricity to recharge, which can limit their range and convenience for long-distance travel.Plug-in hybrid electric vehicle (PHEV)Plug-in hybrid electric vehicles (PHEVs) combine gasoline and electric power sources to provide increased fuel economy over traditional gasoline-powered vehicles. The vehicle can operate in all-electric mode for a limited distance, depending on the size of the battery pack, before the gasoline engine kicks in. This allows PHEVs to have a longer range than pure BEVs while still offering zero tailpipe emissions.Hybrid electric vehicle (HEV)Hybrid electric vehicles (HEVs) combine gasoline and electric power sources but do not require external charging. The electric motor and gasoline engine work together to provide motive force, with the electric motor assisting the gasoline engine under certain conditions to improve fuel economy. HEVs do not have the range limitations of BEVs or PHEVs but still offer improved fuel economy over traditional gasoline-powered vehicles.Hydrogen fuel cell vehiclesFuel cell electric vehicle (FCEV)Fuel cell electric vehicles (FCEVs) use a fuel cell stack to convert hydrogen into electricity, which is then used to power an electric motor that drives the vehicle. The only emission from the vehicle is water vapor, making it a zero-emission vehicle (ZEV). FCEVs have a longer range than battery electric vehicles and can be quickly refueled at a hydrogen fueling station, although hydrogen fueling infrastructure is currently limited in most areas.Hydrogen internal combustion engine vehicle (HICEV)Hydrogen internal combustion engine vehicles (HICEVs) use hydrogen as a fuel for a traditional internal combustion engine, rather than gasoline or diesel fuel. The primary benefit of HICEVs is their ability to emit only water vapor as exhaust, making them a ZEV. However, they still emit carbon dioxide and other greenhouse gases during the production of hydrogen from natural gas, which is currently the primary source of hydrogen.
