You make very good points that I have not seen "shared mobility" advocates address. The idea that people will give up owning cars... well, it presumes a whole lot of other lifestyle changes have happened beforehand. Cars must be very valuable. In a blog explaining why hydrogen will never be a transport fuel,[1] the author mentioned in passing that cars average well under 4% utilization, and the average fill frequency is once per month. To have something so expensive and little used, the option of being able to use it on demand must be highly valuable. And as you say it's secure storage and portage. 1. In a month, a steel-walled 200 bar hydrogen tank with 10 mm (0.4 inch) thick walls will lose over 80% of its hydrogen through its walls.
