A hydrogen highway is a chain of hydrogen-equipped public filling stations, along a road or highway, that allows hydrogen powered cars to travel.[1] It is an element of the hydrogen infrastructure that is generally assumed to be a pre-requisite for mass utilization of hydrogen cars. For instance, William Clay Ford Jr. has stated that infrastructure is one of three factors (also including costs and manufacturability in high volumes) that hold back the marketability of fuel cell cars.

Supply issues, cost and pollution

Hydrogen fueling stations generally receive deliveries of hydrogen by tanker truck from hydrogen suppliers.[2] An interruption at a hydrogen supply facility can shut down multiple hydrogen fueling stations.[3] A hydrogen fueling station costs between $1 million and $4 million to build.[4]

As of 2019, 98% of hydrogen is produced by steam methane reforming, which emits carbon dioxide.[5] The bulk of hydrogen is also transported in trucks, so pollution is emitted in its transportation.[2]
