I'm not a chemist, but I'm sure there are many here on HN. AFAIK hydrogen mixed with oxygen ranges from 'highly flammable' to 'highly explosive'. Wouldn't hydrogen cars (or any hydrogen power for that matter) be much more dangerous compared to fossil fuels or electricity? Sure, a lithium battery burning in an underground parking garage is dangerous. But having a car leaking hydrogen into an underground parking sounds like a recipe for disaster. Can anyone with chemistry experience shed some light on the dangers if say 10% of cars in an urban environment were to be equiped with high pressure hydrogen tanks?

"wide variety of applications, including mobility such as trucks, buses, trains and ships, as well as stationary generators" Now that lithium batteries have been proven to work well I don't think anyone is still seriously thinking about hydrogen cars. There's definitely a cost/weight/safety/efficiency trade off that makes hydrogen just very unattractive for cars or really any consumer application.
