Abstract
A hydrogen leakage detection device includes a controller configured to receive a first hydrogen consumption amount from each of the hydrogen consumption devices via a communication device; control a pressure regulator such that a first flow amount of hydrogen gas flowing in a hydrogen pipeline corresponds to an amount equal to a first sum of the first hydrogen consumption amounts; in response to a check instruction outputted based on establishment of a particular condition or at a particular timing, receive a second hydrogen consumption amount from each of the hydrogen consumption devices and a second flow amount of the hydrogen gas; determine whether the second flow amount is greater than a second sum of the second hydrogen consumption amounts; and in response to a determination that the second flow amount is greater than the second sum of the second hydrogen consumption amounts, determine that a hydrogen gas leak has occurred.
