energy in electric vehicles then using electricity to create hydrogen via electrolysis of water. After the hydrogen is produced it must be compressed in storage tanks requiring more electrical energy.

Battery powered.electric vehicles are 3 to 6 time more efficent at using electrical power in this usage.

Hydrigen is not a fuel it is an energy carrier. It takes energy to create it. Either via electrolysis of water or by reforming fossil fuels like natural gas to convert it to hydrogen and carbon by products
Niether process is efficient or provide a cost advantage over electric vehicle or efficient fossil fuels powered vehicle such as hybrids.

All of these experimental hydrogen fueling stations in states like California are subsidized. The cost of the hydrogen is not the real cost. It is being sold at a loss or given away in these pilot programs.
