What about hydrogen cars?

Hydrogen fuel cell vehicles (FCVs) are another alternative to internal combustion engine vehicles, but are less than half as efficient as electric vehicles (EVs).  FCVs have some engineering challenges to overcome before they will be widely available in the light duty passenger vehicle market; these include vehicle cost, hydrogen cost, hydrogen storage and delivery, and competition with other technologies such as EVs.  The electrical grid already exists for plug-in vehicles, and current trends show that plug-in vehicles are quickly becoming the dominant alternative to internal combustion engine vehicles.  There are currently approximately 6,500 FCVs on the road as of 2018*, compared to almost one million EVs.
