If you were to convert gas stations to hydrogen stations, you'd have to change out all the tanks and fluid handling equipment.

Equipment to handle fluid at atmospheric pressure is very different from that which handles high pressure gas/fluid.

You'd have to replace the underground tanks, all of the associate plumbing, and the pumps on the surface. That's going to cost just as much as building the gas station in the first place.

That's assuming you're trucking in liquid hydrogen. If you want to put it in underground pipes, you're going to have an even worse time. You need heavily insulated pipes running at extreme pressures. Those pipes also need special coatings to prevent the hydrogen atoms from leaking out.

This is far from a simple case of "just reuse gas stations". Hydrogen presents an order of magnitude more problems than gasoline. Gasoline's main benefit is that it's pretty stable at room temperature and atmospheric pressure. It's easy to handle and store, and vanishes into the air at a much slower rate.

True, but it is not much different than gas stations selling CNG or LPG. It's doable since the land is there and you are still dealing with flammable chemicals. There is a lot of common expertise. Many hydrogen stations are in fact converted gas stations in California.
