Friday/ pump some hydrogen

Here is a hydrogen gas dispenser station that I noticed as I was filling up my rental car with fossil fuel gas on Thursday. Whoah, cool !  Let me take a closer look, I thought.  I’m still on the look-out for catching a glimpse of a FCV (Fuel Cell Vehicle, such as a Toyota Mirai), on the freeways here in California.

A hydrogen gas station near San Francisco airport. ‘True zero’, says the logo on the pump. There are only about 60 hydrogen stations in operation in the USA right now, clustered in and around San Francisco, San Jose and Los Angeles.

H35 and H70 stands for different pressures of the hydrogen gas. For H35, the fuel goes directly into the vehicle. If the driver is dispensing fuel at H70, the hydrogen first goes into another small compressor where the fuel is pre-cooled and compressed even more before dispensing. And the cost? About $16 per kilogram. A Toyota Mirai will take about 5 kg of hydrogen fuel.
