That particular BMW effectively one-of-a-kind in that it is 1) internal combustion rather than fuel cell, and 2) stores its fuel as a liquid rather than a compressed gas. The liquid storage is a consequence of being ICE because it is required to get even remotely reasonable range out of something as inefficient as ICE combustion of hydrogen.

fuel cell vehicles like the Mirai still have a number of problems, but they have actually done a very good job with fuel storage and range using compressed hydrogen and don't have any of the limitations of the BMW such as leaking hydrogen or losing massive internal volume to the fuel storage.
