Using "..improved technology to produce the fuel using electrolyzers—devices that split water into hydrogen and oxygen using electricity from renewable sources—is shaking up the clean energy world. "

Forbes (11/17/2022)

"Researchers at Ben-Gurion University of the Negev in Beersheba (BGU) and the Technion-Israel Institute of Technology in Haifa may have identified a way to improve the process and reduce costs" using photoelectrochemistry.

How is the hydrogen stored? Is it just as a compressed gas, or is there more to it?

Since the tanks are not insulated for cryogenic storage the hydrogen is still in its gaseous state at ambient temperature. All hydrogen tanks are regulated worldwide, and the regulations significantly restrict the leak rate to miniscule levels. The tanks are engineered using three separate layers. One layer is a plastic inner lining, the next is a sheet of carbon fiber, and finally an outer layer of glass fiber completes the seal.

It's my understanding that one could fill a tank designed to contain H2 (g) in your garage and if you measured the pressure after a decade of simply letting the tank sit in place the pressure gage wouldn't record any significant loss of gas. I am also confident that engineers have mitigated the Joule-Thomson effect that very effectively chills the filling nozzles as one fills up a tank for 5 minutes.
