What kind of safety issues are to be expected with this tech? I mean... it's hydrogen gas...

Safety is important! Compressed hydrogen isn't like a bomb, the hydrogen needs oxygen to ignite. So if one of these cars crashes or gets rear ended it's not like an explosion will take out a city block or anything like that. Testing shows that hydrogen cars are generally as safe or safer than gasoline or diesel vehicles because escaped hydrogen floats into space at 45 MPH, whereas gasoline or diesel forms a puddle and if it ignites, there's a serious fire.

Article on a test done some years ago comparing gasoline and hydrogen leaks:

EV World: Hydrogen Car Fire Surprise
Video documents results of hydrogen and gasoline car fires.

On a dark Florida night in 2001 an unusual and revealing experiment took place. Dr. Michael Swain with the University of Miami at Coral Gables attempted to simulate two car fires, one created by a 1/16th inch puncture in a gasoline fuel line, the other by a leaking hydrogen connector. He video taped the experiment to document what would happen if the leaks ignited. As the photos below clearly demonstrate, consumer fears about hydrogen as a transportation fuel would seem to be pretty much unfounded.more: http://evworld.com/article.cfm?storyid=482

Hydrogen is safer than propane, if propane leaks it sinks and collects, waiting for a spark.

Awesome, thank you!!

This tech seems... well... entirely reminiscent of water powered cars, Stan Meyer I think was his name? Isn't this literally the water powered car tech? Are they just bypassing the splitting of water in the vehicle itself in favour of pure hydrogen gas fueling stations?

Stan Meyer was using hydrogen generated on board the vehicle in the vehicle's internal combustion engine. There is more to exactly what he was doing that involved resonance but I don't know very much about it.

Most of today's hydrogen tech uses hydrogen in fuel cells, which have no moving parts (except fans to blow air and H2 through the stack). No combustion with fuel cells, just a chemical reaction.

Greek physicist Petros Zografos is doing something like Stan Meyers did, PBS broadcast a segment on him and then pulled it, saying they should have been more "skeptical".

These guys are (or were, in Stan's case) on to something, I'm convinced. The Wiki page on Stan's death is interesting. This tech will disrupt a huge chunk of the status quo so it isn't surprising that there are shenanigans going on.
