As a gas the H2 will find its way up into the atmosphere where it will ultimately be converted to H2O. Even if it did not there are biological process which result in free H2; it's benign.
Another aside with H2 is that if it is stored as a cryogenic liquid, such as might be the case in a car fuel tank, it is necessary to boil off some of the contents in order to maintain the tank temperature. Your H2 fuel tank must leak, by design.
